본 명세서 내에서 '유입수(inflow)' 라는 용어는 포괄적인 의미로 사용된다. 즉, 어떤 처리조나 배수관 내로 유입되는 물을 포괄적으로 의미하는 것으로 사용된다. 예를 들어, 유입수는 초기 우수, 하수, 중수(예컨대, 건물로부터 유출되는 구정물), 또는 하수의 생물학적 처리 후 재이용을 위한 하수처리수 등일 수 있다. 또한, 본 명세서 내에서 단지 '물' 또는 '유입수'라고만 기술되어 있으나, 여기서의 '물' 또는 '유입수'는 오염물질(조대물질, 유기물질, 입자성 오염물질, 부유물질(SS), 중금속, 질소, 인 등)이 함유 또는 혼합된 물을 의미하는 것으로 기술되었다.As used herein, the term 'inflow' is used in a generic sense. In other words, it is used to mean the water flowing into any treatment tank or drain pipe. For example, the influent may be initial stormwater, sewage, heavy water (eg, old water flowing out of a building), or sewage treatment for reuse after biological treatment of sewage. In addition, although only 'water' or 'influent water' is described herein, the term 'water' or 'influent water' refers to contaminants (coarse material, organic material, particulate contaminants, suspended solids (SS), heavy metals). , Nitrogen, phosphorus, etc.) have been described as meaning water containing or mixed.
유입수를 저장하는 저장조(110)는 전술한 바와 같이, 초기 우수, 하수, 중수 또는 하수처리수 등의 유입수를 유입시켜(화살표 a1), 이로부터 오염물질을 침전시킨다. 저장조(110)의 바닥(116)은 오염물질이 용이하게 응집되어 침전 슬러지를 생산하여 용이하게 외부로 배출해 낼 수 있도록 경사진 구조로 형성되는 것이 바람직하다. 여기서 침전되는 오염물질은, 예를 들어, 조대 물질 또는 비교적 고 비중의 입자이다. 따라서, 이와 같은 고 비중의 입자는 1차적으로 유입조(120) 이전 단계에서 저장조(110)에서 1차적으로 침전된다. 저장조(110)의 바닥(116) 상에 침전된 슬러지는 외부에 설치된 석션 펌프(suction pump)(미도시)를 통해 외부로 배출된다(화살표 a2). 저장조(110) 내에는 유입조(120) 내로 물을 펌핑할 수 있도록 저장조 펌프(112)가 마련된다.As described above, the storage tank 110 storing the inflow water introduces inflow water such as initial rainwater, sewage water, heavy water, or sewage treatment water (arrow a1) to precipitate contaminants therefrom. The bottom 116 of the reservoir 110 is preferably formed in an inclined structure so that contaminants can be easily aggregated to produce precipitated sludge and easily discharged to the outside. The pollutants precipitated here are, for example, coarse matter or particles of relatively high specific gravity. Therefore, such high specific gravity particles are primarily precipitated in the storage tank 110 in the step before the inlet tank 120. The sludge precipitated on the bottom 116 of the reservoir 110 is discharged to the outside through a suction pump (not shown) installed outside (arrow a2). The reservoir 110 is provided with a reservoir pump 112 so as to pump water into the inlet 120.
유입조(120)는 저장조(110) 또는 침전조(140)로부터 물을 펌핑하여 유입시켜 이로부터 바닥(126)에 오염물질을 침전시켜 슬러지를 생산해 낸다. 침전 슬러지는 비교적 고 비중의 오염물질이다. 침전 슬러지는 석션 펌프(미도시)를 통해 외부로 배출된다. 유입조(120)는 저장조(110)로부터 유입되는 물(114를 통해) 또는 침전조(140)로부터 유입되는 물(124를 통해)로부터 오염물질을 침전시켜 침전 슬러지가 생산되기에 유리하도록 바닥부(126)가 경사지게 형성된다. 또한, 유입조(120)는 침전된 오염물질 또는 침전 중에 있는 오염물질이 상 방향으로 역행하지 않도록 경사지게 배치된 경사판(128)을 포함한다. 경사판(128)은 도 1에 도시된 바와 같이, 서로 마주하는 유입조(120)의 두 개의 측벽(1201, 1202)을 따라 길게 형성되어 있으며(도 3의 참조부호 128 참조), 이 두 개의 측벽(1201, 1202)에서부터 중앙으로 뻗어나와 소정의 간격으로 교대로(alternately) 배치되며, 그 중앙이 주변보다 낮도록 경사지게 설치된다. 이러한 구조를 통해, 경사판(128)은 아래로 들어간 오염물질이 다시 위로 상승하지 않도록 할 수 있다. 유입조(120)의 바닥부(126)에 침전된 슬러지는 외부에 설치된 석션 펌프(미도시)를 통해 외부로 배출될 수 있다(화살표 a3 참조).The inflow tank 120 pumps water from the storage tank 110 or the settling tank 140 to precipitate the contaminants on the bottom 126 to produce sludge. Precipitated sludge is a relatively high specific gravity pollutant. The settling sludge is discharged to the outside through a suction pump (not shown). The inflow tank 120 precipitates contaminants from water (through 114) coming from the reservoir 110 or from water (124) coming from the sedimentation tank 140 to advantageously produce the sludge from the bottom ( 126 is formed to be inclined. In addition, the inflow tank 120 includes an inclined plate 128 disposed to be inclined such that the precipitated contaminant or the contaminant in the sedimentation does not return upward. As shown in FIG. 1, the inclined plate 128 is elongated along two sidewalls 1201 and 1202 of the inflow tank 120 facing each other (see reference numeral 128 of FIG. 3). It extends from 1201 and 1202 to the center and is alternately arranged at predetermined intervals, and is installed to be inclined so that the center thereof is lower than the periphery. Through this structure, the swash plate 128 can prevent the contaminants entering the bottom from rising upward again. The sludge deposited on the bottom 126 of the inflow tank 120 may be discharged to the outside through a suction pump (not shown) installed outside (see arrow a3).
침전조(140)는 제2 배수관(133)의 내부를 통해 유입(도 2의 화살표 a8 참조)되어 침전조(140) 내부로 유입되는 물과 함께 존재하는 오염물질을 침전시킨다. 그뿐만 아니라, 침전조(140)는 역세 배수관(137)으로부터 월류수를 더 공급받을 수 있다. 즉, 후술하는 바와 같이, 여과 및 역세부(130)의 작용에 의해 월류하는 경우, 그 월류수가 역세 배수관(137)을 통해 침전조(140) 내로 유입된다. 따라서, 침전조(140)는 제2 배수관(133)의 내부를 통해 유입되는 물과 역세 배수관(137)으로부터 유입되는 월류수로부터 오염물질을 침전시키는 부분이다. 침전조(140)는 산소가 거의 없는 상태에서 침전 반응이 이루어지므로, 다르게는 무산소조로 일컬어질 수 있다. 침전조(140)는 그 내부로 유입되는 물로부터 오염물질이 침전되어 그로부터 침전 슬러지가 생산되기에 유리하도록 바닥부(146)가 경사지게 형성된다. 따라서, 침전조(140)의 경사진 바닥부(146)의 구조로 인해, 침전 슬러지의 응집이 잘 이루어질 수 있다. 또한, 침전조(140)는 전술한 유입조(120)의 구조와 유사하게 침전된 오염물질 또는 침전 중에 있는 오염물질이 상 방향으로 역행하지 않도록 경사판(148)을 포함한다. 경사판(148)은, 서로 마주하는 침전조(140)의 두 개의 측벽(1401, 1402)을 따라 길게 형성되어 있으며, 이 두 개의 측벽(1401, 1402)에서부터 중앙으로 뻗어나와 소정의 간격으로 교대로 배치되며, 중앙이 주변보다 낮도록 경사지게 형성된다. 이러한 구조를 통해, 경사판(148)은 침전한 슬러지가 다시 위로 부상하지 않도록 할 수 있다. 침전조(140)의 바닥부(146)에 침전된 슬러지는 외부에 설치된 석션 펌프(미도시)를 통해 외부로 배출될 수 있다(화살표 a4 참조). 또한, 침전조(140) 내에는 유입조(120) 내로 침전조(140) 내의 물을 펌핑할 수 있도록 침전조 펌프(122)가 마련된다. 전술한 저장조 펌프(112)와 이 침전조 펌프(122)는 서로 번갈아가며 동작한다. 이에 관하여는 전체적인 동작 설명에서 함께 구체적으로 기술될 것이다.The settling tank 140 is introduced through the inside of the second drain pipe 133 (see arrow a8 in FIG. 2) to precipitate the contaminants present together with the water flowing into the settling tank 140. In addition, the settling tank 140 may be further supplied with the overflow water from the backwash drain pipe (137). That is, as will be described later, in the case of overflowing by the action of the filtration and the backwashing unit 130, the overflowed water flows into the settling tank 140 through the backwashing drainage pipe 137. Therefore, the settling tank 140 is a portion for precipitating contaminants from the water flowing through the inside of the second drain pipe 133 and the overflow water flowing from the backwash drain pipe 137. Precipitation tank 140, because the precipitation reaction is made in the state that there is almost no oxygen, otherwise it may be referred to as an anoxic tank. The sedimentation tank 140 has a bottom portion 146 formed to be inclined so that contaminants are precipitated from the water flowing into the sediment and sludge is produced therefrom. Therefore, due to the structure of the inclined bottom portion 146 of the settling tank 140, aggregation of the settling sludge can be made well. In addition, the settling tank 140 includes an inclined plate 148 to prevent the settled contaminants or contaminants in the settling in the upward direction similar to the structure of the inlet 120 described above. The inclined plate 148 is formed along two side walls 1401 and 1402 of the settling tank 140 facing each other, extends from the two side walls 1401 and 1402 to the center, and are alternately arranged at predetermined intervals. It is formed to be inclined so that the center is lower than the surroundings. Through this structure, the inclined plate 148 may prevent the precipitated sludge from rising upward again. The sludge precipitated at the bottom 146 of the settling tank 140 may be discharged to the outside through a suction pump (not shown) installed outside (see arrow a4). In addition, in the settling tank 140, a settling tank pump 122 is provided to pump water in the settling tank 140 into the inlet 120. The above-described reservoir pump 112 and the sedimentation tank pump 122 alternately operate with each other. This will be described in detail together in the overall operation description.
여과 및 역세부(130)에서, 여재층(131)은 유입조(120) 측에서 유입되는 물을 여과 및 역세 과정을 통해 호기성 미생물 및 혐기성 미생물로 수처리하는 부분이다. 여재층(131) 재료로서는, 예를 들어, 마사토, 제올라이트, 섬유로 제작된 부직포 판 부재의 일종으로서 여과 효과를 갖는 사란 락(saran lock) 생물막 여재 또는 스펀지 등 재질의 담체 등이 사용될 수 있다. 또한, 여재층(131)은 입자 크기에 따라 수직으로 적층될 수 있다(예를 들어, 하부는 큰 입자로 구성하고 상부는 작은 입자로 구성할 수 있음). 여재층(131)에서는 이하에서 더 상세히 설명되는 바와 같이 여과 및 역세 과정이 수행되는데, 이 여재층(131) 내에서 하향류와 상향류의 반복적인 흐름에 따라 호기성 미생물 및 혐기성 미생물의 작용에 의해, 오염물질 내에 포함된 암모니아성 질소(NH3-N)가 질산화 과정에 의해 질산성 질소(NO3-N)로 되고, 이후 아질산성 질소(NO2-N)로 된 후, 최종적으로 N2로 되는 탈질화 과정이 이루어질 수 있다. 대체로 오염물질 내의 질소 성분은 호기성 미생물에 의해 질산화되고, 혐기성 미생물에 탈질화된다.In the filtration and backwashing unit 130, the filter media layer 131 is a portion for treating water introduced from the inflow tank 120 into aerobic and anaerobic microorganisms through filtration and backwashing. As the material of the media layer 131, a carrier made of a material such as a saran lock biofilm media or a sponge having a filtration effect can be used, for example, as a kind of non-woven plate member made of masato, zeolite, or fiber. In addition, the media layer 131 may be stacked vertically according to the particle size (for example, the lower portion may be composed of large particles and the upper portion may be composed of small particles). Filtration and backwashing process is performed in the filter medium layer 131 as described in more detail below, by the action of aerobic microorganisms and anaerobic microorganisms in accordance with the repetitive flow of downflow and upflow in the filter medium layer 131 , Ammonia nitrogen (NH 3 -N) contained in the contaminant is converted to nitrate nitrogen (NO 3 -N) by nitrification process, and then to nitrite nitrogen (NO 2 -N), and finally N 2 Denitrification process can be made. As a rule, the nitrogen component in the contaminants is nitrified by aerobic microorganisms and denitrified by anaerobic microorganisms.
제1 배수관(132) 및 제2 배수관(133)은 서로 결합된 상태로 여재층(131) 내에 관입되는데, 제1 배수관(132)의 상부(1321)는 밀폐되고 하부(1322)는 개방되도록 형성되는 반면, 제2 배수관(133)의 상부 및 하부는 개방되어 침전조(140) 내로 물을 유입시킬 수 있다. 제1 배수관(132)은 그 하단(bottom-end)(1322)이 여재층의 하단(참조부호 135 참조)보다 높게 위치한다. 도 1에 도시된 예에서는 하단의 높이가 대체로 L5 라인과 유사하도록 설치되어 있다. 제2 배수관(133)은 제1 배수관(132) 내에 삽입되며, 그 상단의 높이는 제1 배수관(132)의 상단(1321) 내부보다 낮다. 이하에서는, 제1 배수관(132)과 제2 배수관(133)의 이러한 결합 구조를 간단히 배수관 결합구조로 일컫는다.The first drain pipe 132 and the second drain pipe 133 are introduced into the filter layer 131 in a state where they are coupled to each other, and the upper part 1321 of the first drain pipe 132 is sealed and the lower 1322 is opened. On the other hand, the upper and lower portions of the second drain pipe 133 may be opened to introduce water into the settling tank 140. The first drain pipe 132 has a bottom end 1322 positioned higher than a bottom end of the media layer (see reference numeral 135). In the example shown in FIG. 1, the bottom is provided so that the height is generally similar to the L5 line. The second drain pipe 133 is inserted into the first drain pipe 132, and the height of the upper end thereof is lower than the inside of the upper end 1321 of the first drain pipe 132. Hereinafter, this coupling structure of the first drain pipe 132 and the second drain pipe 133 is simply referred to as a drain pipe coupling structure.
제1 배수관(132) 내에 제2 배수관(133)이 삽입되어 있는 구조, 즉 배수관 결합 구조를 통한 처리 과정을 살펴보면, 일단 여재층(131)의 하부에서부터 수위가 점차 높아지는 경우, 배수관 결합구조 내부, 즉 제1 배수관(132)의 내부 영역이면서 제2 배수관(133)의 외부 영역의 수위도 동일하게 높아진다. 계속해서 수위가 높아지다가, 수위가 제2 배수관(133)의 상단보다 높아지는 경우, 제1 배수관(132)의 내부 영역이면서 제2 배수관(133)의 외부 영역으로 유입되는 물은 제2 배수관(133)의 내부를 통해 침전조(140)로 유출되기 시작하고, 이러한 제2 배수관(133)에서부터 침전조(140)로의 유출은 여재층(131) 내의 수위가 제1 배수관(132)의 하단과 대체로 동일하게 될 때까지(즉, 수위가 L5로 될 때까지) 계속된다. 배수관 결합구조의 내부 압력과 관련하여 침전조(140) 측으로 물이 유출되는 과정을 간단히 살펴보면, 먼저 제2 배수관(133)의 상단보다 수위가 높아지는 시점에 제2 배수관(133)의 내부 영역을 통해(도 2의 화살표 a8) 물이 침전조(140) 측으로 일부 유출되고, 이와 동시에 제2 배수관(133)과 제1 배수관(132) 사이의 영역의 압력은 낮아지게 되고, 그 결과 그 낮아진 압력 하의 제2 배수관(133)과 제1 배수관(132) 사이의 영역으로 계속해서 물이 유입되어(도 2의 화살표 a6, a7) 그 영역으로 채워지게 되는데, 이러한 과정은 여재층(131) 내의 수위가 제1 배수관(132)의 하단과 대체로 동일하게 될 때까지(즉, 수위가 L5로 될 때까지) 계속된다.Looking at the structure in which the second drain pipe 133 is inserted into the first drain pipe 132, that is, the process through the drain pipe coupling structure, once the water level is gradually increased from the lower portion of the filter layer 131, the inside of the drain pipe coupling structure, That is, the water level of the inner region of the first drain pipe 132 and the outer region of the second drain pipe 133 is also increased. If the water level is continuously increased and the water level is higher than the upper end of the second drain pipe 133, the water flowing into the outer region of the second drain pipe 133 while being the inner region of the first drain pipe 132 is the second drain pipe 133. The outflow to the settling tank 140 through the inside of the), the discharge from the second drain pipe 133 to the settling tank 140 has the same level as the lower end of the first drain pipe 132 in the filter medium layer 131 Until it reaches (i.e. until the water level reaches L5). Looking at the flow of water to the sedimentation tank 140 in relation to the internal pressure of the drain pipe coupling structure briefly, first through the inner region of the second drain pipe 133 at the time when the water level is higher than the top of the second drain pipe 133 ( Arrow a8) in FIG. 2 partially flows out to the settling tank 140, and at the same time, the pressure in the region between the second drain pipe 133 and the first drain pipe 132 is lowered, and as a result, the second under the lower pressure Water continues to flow into the area between the drain pipe 133 and the first drain pipe 132 (arrows a6 and a7 in FIG. 2), so that the water level in the media layer 131 is filled in the first layer. It continues until it is approximately equal to the bottom of the drain 132 (ie, until the water level is L5).
제3 배수관(134)은 여재층(131)의 상부에서 유입조(120)로부터 여재층(131)으로 물을 공급하는 부분이다. 제3 배수관(134)은 여재층(131) 방향으로 소정의 간격으로 형성되어 유입조(120)로부터 월류된 물을 여재층(131)으로 공급할 수 있도록 하기 위한 복수 개의 배출구(1341)를 포함한다. 앞서 간단히 언급한 바와 같이, 제3 배수관(134)으로 월류하는 물은 저장조 펌프(112) 및 침전조 펌프(122) 중 어느 하나에 의해 펌핑되어 유입조(120) 내에서 비교적 고비중 입자를 침전에 의해 제거한 이후의 물이다.The third drain pipe 134 is a portion for supplying water from the inflow tank 120 to the filter medium layer 131 at the upper portion of the filter medium layer 131. The third drain pipe 134 includes a plurality of discharge ports 1321 formed at predetermined intervals in the direction of the filter medium layer 131 to supply the water overflowed from the inflow tank 120 to the filter medium layer 131. . As briefly mentioned above, the water flowing over to the third drain pipe 134 is pumped by either the reservoir pump 112 or the sedimentation tank pump 122 to deposit relatively high specific gravity particles in the inlet tank 120 to the sedimentation. By water after removal.
여재층(131)의 하부에는, 여재층(131)을 지지하고 여재층(131)을 통과하는 물을 하부로 배출하기 위한 지지망(135)이 더 구비된다. 또한, 지지망(135)과 여과 및 역세부(130)의 바닥(139) 사이에서 지지망(135)을 지지하고 지지망(135)의 공극들 사이로 나오는 물을 제1 배수관(132) 측, 즉, 배수관 결합구조 측으로 공급하기 위한 공간을 형성하는 지지부재(136)를 갖는다. 지지망(135)의 공극들의 크기는 지지망(135)에 의해 지지되는 여과층(131)의 입자의 크기보다 작을 것이 요구되고, 지지부재(136)는 도 1 및 도 2에 예시된 바와 같이, 예를 들어, 단면적이 삼각형이고 폭이 좁으면서 긴 삼각 기둥 형상의 복수 개의 로드(rod)들이 소정 간격으로 길게 배열되어 지지망(135)을 아래에서 지지하면서 지지망(135)의 공극들 사이로 나오는 물을 배수관 결합구조 측으로 공급(도 2의 화살표 a6 및 a7 참조)하도록 구성될 수 있다. 도 1 및 도 2의 지지부재(136)의 형상은 예시된 것에 불과하므로, 이러한 삼각기둥 형상의 로드들로 한정되는 것은 아니다.A lower portion of the filter layer 131 is further provided with a support net 135 for supporting the filter layer 131 and discharging water passing through the filter layer 131 downward. In addition, water supporting the support network 135 between the support network 135 and the bottom 139 of the filtration and backwashing unit 130 and water flowing between the pores of the support network 135 is discharged to the first drain pipe 132 side, that is, the drain pipe. It has a support member 136 that forms a space for supply to the side of the coupling structure. The size of the pores of the support net 135 is required to be smaller than the size of the particles of the filtration layer 131 supported by the support net 135, and the support member 136 is illustrated, as illustrated in FIGS. 1 and 2. For example, a plurality of rods having a triangular cross section and a narrow triangular column shape are arranged long at predetermined intervals to support the support network 135 from below, and drain water from the air gaps between the pores of the support network 135. It can be configured to feed (see arrows a6 and a7 in FIG. 2) to the coupling structure side. Since the shape of the supporting member 136 of Figs. 1 and 2 is only illustrated, it is not limited to such triangular prism-shaped rods.
더 나아가, 상기 여과 및 역세부(130)는 제2 배수관(133)의 내부를 통해 침전조(140)로 물을 유출하는 동안에도 계속해서 수위가 높아지는 경우, 침전조(140)로 물을 더 유출시켜 여재층(131) 내의 수위를 조절하기 위한 역세 배수관(137)을 더 포함한다. 역세 배수관(137)은 제2 배수관(133)의 상단(top-end)보다 낮은 위치에서부터 나와 침전조(140)로 이어지도록 설치되어, 월류수를 침전조(140) 측으로 유입시킨다. 이 때 월류수에는 역세에 의해 유출되는 오염물질이나 미생물 덩어리들이 포함되어 있을 수 있다. 도 1에서 L1은 제2 배수관(133)의 상단의 높이이고, L2는 역세 배수관(137)의 설치 높이로서, L2는 L1보다 낮게 위치하도록 한다. 여과 및 역세부(130) 측으로 유입되는 수량이 적은 경우에는, 배수관 결합구조(132, 133)에 의해서만 배출되고, 배수관 결합구조(132, 133)의 배출 용량을 초과하여 수위가 계속 증가하는 경우, 배수관 결합구조에 의한 배출과 함께 역세 배수관(137)을 통한 배출도 병행된다.Furthermore, the filtration and backwashing unit 130 further flows out the water to the settling tank 140 when the water level continues to increase while the water flows out to the settling tank 140 through the inside of the second drain pipe 133. A backwash drain pipe 137 for adjusting the water level in the media layer 131 is further included. The backwash drain pipe 137 is installed to extend from the position lower than the top-end of the second drain pipe 133 to the sedimentation tank 140 to introduce the overflow water into the sedimentation tank 140. The overflow water may contain contaminants or microbial masses released by backwash. In FIG. 1, L1 is the height of the upper end of the second drain pipe 133, L2 is the installation height of the backwash drain pipe 137, and L2 is positioned lower than L1. When the amount of water flowing into the filtration and backwashing part 130 is small, the water is discharged only by the drain pipe coupling structures 132 and 133 and the water level continues to increase beyond the discharge capacity of the drain pipe coupling structures 132 and 133. Along with the discharge by the drain pipe coupling structure, the discharge through the backwash drain pipe 137 is also parallel.
본 발명의 일 실시예에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치는, 침전조(140) 이후의 수처리를 위해, 최종 처리수조(150) 및 소독조(160)를 더 포함할 수 있다. 최종 처리수조(150)에서는 침전조(140) 내에서 오염물질이 침전된 후 월류하는 물에 잔존하는 오염물질을 최종적으로 침전시키며, 소독조(160)는 최종 처리수조(150)에서의 침전 이후 물을 소독하기 위한 부분이다. 여기서, 소독조(160)에 염소 같은 소독약품을 주입하기 위한 소독약품 주입구가 별도로 마련될 수 있다. 소독조(160) 내에는 소독 처리된 물을 외부로 배출(화살표 a5 참조)하여 사용할 수 있도록 소독조 펌프(162)가 마련될 수 있다. 최종 처리수조(150)에서 소독조(160)로 물이 월류할 수 있도록 최종 처리수조(150)와 침전조(140) 사이의 벽 높이(L3)보다 최종처리수조(150)와 소독조(160) 사이의 벽 높이(L4)가 더 낮도록 설치된다.The biofilm water treatment apparatus having a non-powered backwashing function according to an embodiment of the present invention may further include a final treatment tank 150 and a disinfection tank 160 for water treatment after the precipitation tank 140. The final treatment tank 150 finally precipitates the contaminants remaining in the overflowed water after the pollutant is precipitated in the sedimentation tank 140, the disinfection tank 160 is the water after the precipitation in the final treatment tank 150 This is for disinfection. In this case, a disinfectant injection hole for injecting a disinfectant such as chlorine into the disinfection tank 160 may be separately provided. The disinfection tank 160 may be provided with a disinfection tank pump 162 to discharge the disinfected water to the outside (see arrow a5). Between the final treatment tank 150 and the disinfection tank 160 than the wall height (L3) between the final treatment tank 150 and the settling tank 140 so that water can flow from the final treatment tank 150 to the disinfection tank 160. The wall height L4 is installed to be lower.
이와 같이, 본 발명의 생물막 수처리 장치는, 도 1 내지 도 4에 도시된 바와 같이 저장조(110), 유입조(120), 그리고 여과 및 역세부(130)를 포함하는 상부층과, 침전조(140), 최종 처리수조(150) 및 소독조(160)를 포함하는 하부층으로 구분될 수 있는 간단한 처리 장치로 구현될 수 있으며, 공기 공급 또는 역세를 위한 별도의 송풍기, 산기시설 등의 설비가 필요없어 비용면에서도 유리하고 에너지 절감 효과를 누릴 수 있다.As such, the biofilm water treatment apparatus of the present invention, as shown in Figures 1 to 4, the upper layer including the reservoir 110, the inflow tank 120, and filtration and backwashing 130, and the settling tank 140 , Can be implemented as a simple treatment device that can be divided into a lower layer including the final treatment tank 150 and the disinfection tank 160, and does not require a separate blower, diffuser facilities for air supply or backwashing In addition, it can be advantageous and can save energy.
이하에서는 도 5를 도 1 내지 도 4와 함께 참조하여, 본 발명에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치의 여과 및 역세 과정을 설명하도록 한다.Hereinafter, the filtration and backwashing process of the biofilm water treatment apparatus having the non-powered backwashing function according to the present invention will be described with reference to FIGS.
여과 및 역세부(130)로 물과 함께 유입되는 오염물질은 물의 흐름(하향류)에 따라 여재층(131)으로 침투한다. 여과 과정은 물이 위에서 아래로 흐르는 하향류에 따라 진행된다. 즉, 여과 과정은 여재층(131)의 상측에서 제3 배수관(134)의 배출구(1341)를 통해 물이 공급되는 경우, 물에 혼합된 오염물질, 예컨대, 유기물질, 미립자, 부유물질 및 중금속 등이 하향류에 따라 여재층(131)의 여재에 의해 여과·흡착되거나 유기물질이 여재층에 존재하는 생물막에 의해 분해되는 과정이다(도 1의 참조부호 ff 참조).The contaminants introduced into the filtration and backwashing unit 130 with water penetrate into the media layer 131 according to the flow of water (downstream). The filtration process proceeds with the downward flow of water from top to bottom. That is, in the filtration process, when water is supplied through the outlet 1321 of the third drain pipe 134 on the upper side of the filter medium layer 131, pollutants mixed with water, for example, organic substances, fine particles, suspended solids and heavy metals. The back is a process of being filtered and adsorbed by the filter media of the filter media layer 131 or decomposed by the biofilm present in the filter media layer (see reference numeral ff in FIG. 1).
이와는 반대로, 계속해서 유입되는 유입수에 의해 여재층(131)의 하부에서부터 상부로의 상향류에 따라 진행되는 과정은 역세(back washing) 과정이다(도 1의 참조부호 bw 참조). 즉, 역세 과정은 여재층(131)의 하부에서 상부로의 물의 흐름에 따라 여재층(131) 내의 오염물질, 즉, 여재층(131) 내에서 여재층 사이에 흡착되어 여재층의 공극을 폐색하는 오염물질 또는 미생물 덩어리가 다시 여재층(131)의 상부로 이동하는 과정이다. 다시 말해, 이렇게 물의 흐름이 상향류와 하향류를 반복하여 흐름으로써 여재 사이의 공극이 폐색되는 것을 방지한다. 여기서, 여재층(131)의 상부는 여재층(131) 중 대체로 제1 배수관(132)의 하단보다 높은 부분으로서 비교적 산소가 많이 존재하는 호기상임에 비해(도 1의 참조부호 ae), 여재층(131)의 하부는 여재층(131) 중 대체로 제1 배수관(132)의 하단보다 낮은 부분으로서 혐기상이다(도 1의 참조부호 an). 본 명세서 내에서 '대체로 제1 배수관(132)의 높이'로 기술한 것은, 실제로 물의 기본적인 성질(표면 장력에서 기인한 성질 등)을 고려할 때, 제2 배수관(133)에 의한 침전조(140)로의 배출시 제1 배수관(132)의 하단과 정확히 일치하는 수위까지 배출되지는 않으므로, 이 점을 고려한 것이다.On the contrary, the process proceeding according to the upward flow from the lower part of the filter layer 131 to the upper part by the influent continuously introduced is a back washing process (see reference numeral bw of FIG. 1). That is, the backwashing process is adsorbed between the contaminants in the media layer 131, that is, the media layer in the media layer 131, as the water flows from the lower part of the media layer 131 to the upper part to block the pores of the media layer Contaminants or microbial lumps are the process of moving back to the upper layer (131). In other words, the water flow is repeated in the upstream and the downstream to prevent the voids between the media from being blocked. Here, the upper part of the filter medium layer 131 is a portion higher than the lower end of the first drain pipe 132 of the filter layer 131 as compared with the aerobic phase in which a relatively large amount of oxygen exists (reference numeral ae in FIG. 1), and the filter layer The lower part of 131 is anaerobic as a lower part of the medial layer 131 than the lower end of the first drain pipe 132 (reference an in FIG. 1). In this specification, what is described as the "height of the first drain pipe 132" is actually referred to the sedimentation tank 140 by the second drain pipe 133 in consideration of the basic properties of water (such as due to surface tension). Since the discharge is not discharged to the water level that exactly matches the lower end of the first drain pipe 132, this point is considered.
여과 및 역세 과정에서 상기 여과 및 역세부(130)는, 여과 과정에서 여재층의 상부에서 하부로 이동한 오염물질을 여재층(131) 내에서 호기성 미생물(aerobe, ae)로 처리한 후, 호기성 미생물의 하부에 존재하는 혐기성 미생물(anaerobe, an)로 처리하고, 혐기성 미생물로 처리한 후, 역세 과정에서 상향류(bw)에 따라 이동한 오염물질을 혐기성 미생물의 상부에 존재하는 호기성 미생물로 처리한다. 호기성 미생물에 의한 오염물질의 처리(S51) 과정에서 오염물질은 질산화된다. 그런 다음, 질산화 과정을 거친 오염물질은 하향류(ff)에 따라 아래로 이동하여 혐기상에 놓이게 된다. 여기서, 질산화 과정을 거친 오염물질은 혐기성 미생물에 의해 탈질화된다(S52). 하지만, 질산화 과정 및 탈질화 과정을 거치더라도 오염물질에서 완전히 질소가 제거된 상태는 아니다. 따라서, 그 상태의 오염물질은 역세 과정에서 상향류에 따라 위로 이동하여 다시 호기상에 놓이게 된다(S53). 여기서, 오염물질은 다시 질산화 과정을 거치게 되고, 이후 다시 하향류에 따라 혐기상으로 이동하여 혐기성 미생물에 의해 탈질화된다(S54). 이후, 물은 탈질화된 오염물질과 함께 제2 배수관(133)의 내부를 통해 무산소조 즉, 침전조(140)로 배출된다(S55). 다시 침전조(140) 내의 물을 유입조(120)로 펌핑함으로써 상기 과정이 반복될 수 있다. 여기서, 여과 과정과 역세 과정, 즉 상향류 및 하향류에 따라 여재층(131) 내의 호기성 미생물 및 혐기성 미생물에 의한 반복적인 처리 과정은 효과적인 탈질화를 위해 수차례 반복될 수 있다.In the filtration and backwashing process, the filtration and backwashing unit 130 is treated with aerobic microorganisms (aerobe, ae) in the mediator layer 131 after the contaminants moved from the top to the bottom of the mediator layer in the filtration process. Treated with anaerobic microorganisms (anaerobe, an) present in the lower part of the microorganisms, treated with anaerobic microorganisms, and then treated with aerobic microorganisms present in the upper part of the anaerobic microorganisms, the contaminants moved by upflow (bw) during the backwashing process. do. During the treatment of contaminants by aerobic microorganisms (S51), the contaminants are nitrified. The nitrified contaminants then move downward along the downflow (ff) and are placed in the anaerobic phase. Here, the contaminants that have undergone nitrification are denitrified by anaerobic microorganisms (S52). However, even after nitrification and denitrification, nitrogen is not completely removed from contaminants. Therefore, the contaminants in the state are moved upward in accordance with the upflow in the backwashing process and placed on the exhalation again (S53). Here, the contaminants are subjected to nitrification again, and then moved to the anaerobic phase according to the downflow again and denitrified by the anaerobic microorganisms (S54). Thereafter, the water is discharged to the anoxic tank, that is, the settling tank 140 through the inside of the second drain pipe 133 together with the denitrified pollutant (S55). The process may be repeated by pumping the water in the settling tank 140 to the inlet 120 again. Here, the repetitive treatment by the aerobic and anaerobic microorganisms in the filter layer 131 according to the filtration process and the backwashing process, that is, upstream and downstream, may be repeated several times for effective denitrification.
나아가, 여재층(131)의 상부에는 예를 들어, 꽃창포, 갈대 등과 같은 뿌리 발달 식물이 더 식재될 수 있다. 식재된 뿌리 발달 식물의 뿌리는 여재층(131) 내에서, 여재층(131)으로 유입되는 물에 혼합된 질소 또는 인을 흡수하도록 하여, 뿌리 발달 식물의 영양 물질로 이용될 수 있도록 할 수 있다. 뿌리 발달 식물이 채용되는 경우, 수중 오염물질 중 특히 질소, 인, 중금속 등을 식물의 뿌리에서 흡착 및 흡수하고, 식물의 뿌리에서 증식하는 미생물에 의해 오염물질(예컨대, 유기물질)을 분해할 수 있다. 또한 식물의 뿌리가 여재 사이에 성장하여 여재의 기능을 더욱 강화하고 여재의 폐색을 효과적으로 방지할 수 있다.Furthermore, root development plants such as irises and reeds may be further planted on the upper portion of the filter layer 131. The root of the planted root development plant may absorb nitrogen or phosphorus mixed in the water flowing into the medial layer 131 in the medial layer 131, and thus may be used as a nutritional substance of the root development plant. . When a root development plant is employed, it is possible to absorb and absorb nitrogen, phosphorus, heavy metals, etc., among the pollutants in the water, from the roots of the plants, and to decompose pollutants (eg, organic substances) by microorganisms that proliferate in the roots of the plants. have. In addition, the roots of the plants grow between the media can further enhance the function of the media and effectively prevent the blockage of media.
도 6은 본 발명의 일 실시예에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치의 전체 과정을 단계로 구분하여 설명하기 위한 블록도로서, 도 6을 도 1 내지 도 4와 함께 참조하여, 생물막 수처리 장치의 전체적인 처리 과정 및 효과를 설명하면 이하와 같다.FIG. 6 is a block diagram illustrating the entire process of a biofilm water treatment apparatus having a non-powered backwashing function according to an embodiment of the present disclosure in stages. Referring to FIG. 6 together with FIGS. The overall treatment process and effects of are as follows.
먼저, 저장조 펌프(112) 및 침전조 펌프(122) 중 어느 하나에 의해 펌핑된 물이 유입조(120) 내로 유입된다. 즉, 저장조(110)로부터 유입조(120)로 물을 공급하지 않을 경우 침전조(140) 내의 물을 침전조 펌프(122)로 펌핑하여 순환시킨다. 유입된 물은 유입조(120) 내에서 침전 과정을 거치는데, 여기서 비교적 고 비중의 오염물질이 침전되고(S61), 여기서 바닥에 응집된 침전 슬러지는 별도의 석션 펌프를 통해 외부로 배출된다. 그런 다음, 계속해서 유입조(120) 내의 수위가 높아져서 월류하여 제3 배수관(134)을 통해 여과 및 역세부(130) 측으로 오염물질이 포함된 물이 공급된다. 물이 공급되는 경우, 앞서 설명한 바와 같이 여재층(131)에서 생물막 여과가 이루어지는데, 먼저 호기성 미생물에 의해 질산화가 진행되고(S62), 하향류에 따라 아래로 이동하여 혐기성 미생물에 의해 탈질화가 이루어진다(S63). 앞서 언급한 바와 같이, S62와 S63 과정은 수위가 높아지는 경우, 즉 상향류에 따라 S63 과정 이후 S62 과정 및 S63 과정이 반복되어 탈질 효율이 더욱 높아질 수 있다. 계속해서, 탈질 과정을 거친 이후 오염물질을 함유한 물은 제2 배수관(133)을 통해 침전조(140)로 유입된다. 물론, 전술한 바와 같이, 침전조(140)로 유입되는 물에는, 여재층(131) 내의 수위가 계속 상승하여 역세 배수관(137)을 통해 배출된 물도 있다. 이러한 침전조(140) 내의 물은 무산소조인 침전조(140) 내에서 침전 과정을 거친다(S64). 한편, 침전조(140)에서는 계속해서 침전조 펌프(122)를 작동시켜 유입조(120) 내로 침전조(140) 내의 물을 펌핑할 수 있고, 여과 및 역세 과정을 포함하여 생물막 여과(S62, S63) 및 침전조(140)로부터의 펌핑을 통한 내부 순환 싸이클을 통해, 질소, 인을 포함하는 각종 오염물질을 효율적으로 제거할 수 있다. 최종적으로, 오염물질이 제거된 유입수는 최종 처리수조(150)와 소독조(160)을 거쳐 방류된다(S65). 한편, 물속의 인은 혐기조건하에서는 수중으로 배출되지만, 호기조건하에서는 호기성 미생물이 인을 섭취하고 있거나 인을 섭취한 미생물이 슬러지화되어 외부로 방출되게 된다.First, water pumped by any one of the reservoir pump 112 and the sedimentation tank pump 122 is introduced into the inflow tank 120. That is, when water is not supplied from the storage tank 110 to the inflow tank 120, the water in the settling tank 140 is pumped to the settling tank pump 122 and circulated. The introduced water is subjected to the precipitation process in the inflow tank 120, where a relatively high specific gravity of contaminants are precipitated (S61), where the sediment sludge agglomerated at the bottom is discharged to the outside through a separate suction pump. Then, the water level in the inflow tank 120 is continuously increased so that water containing contaminants is supplied to the filtration and backwashing unit 130 through the third drain pipe 134. When water is supplied, biofilm filtration is performed in the filter medium layer 131 as described above. First, nitrification proceeds by an aerobic microorganism (S62), and downwards by downward flow to denitrification by anaerobic microorganisms. (S63). As mentioned above, the process of S62 and S63 may be increased when the water level is increased, that is, the S62 process and the S63 process are repeated after the S63 process according to the upstream. Subsequently, after the denitrification process, the water containing the contaminant is introduced into the settling tank 140 through the second drain pipe 133. Of course, as described above, the water flowing into the settling tank 140, the water level in the filter medium layer 131 continues to rise, there is also water discharged through the backwash drain pipe (137). The water in the settling tank 140 is subjected to the settling process in the settling tank 140, an anoxic tank (S64). On the other hand, in the sedimentation tank 140 to operate the sedimentation tank pump 122 to pump the water in the sedimentation tank 140 into the inlet tank 120, including biofilm filtration (S62, S63) and filtration and backwashing process and Through the internal circulation cycle through the pumping from the settling tank 140, it is possible to efficiently remove various contaminants including nitrogen, phosphorus. Finally, the influent water from which the contaminants have been removed is discharged through the final treatment tank 150 and the disinfection tank 160 (S65). On the other hand, phosphorus in the water is discharged into the water under anaerobic conditions, but under aerobic conditions, aerobic microorganisms are ingesting phosphorus or microorganisms ingesting phosphorus are sludged and released to the outside.
이와 같이 하여, 물이 여재층(131) 내의 여재를 통과하는 도중에, 여재의 표면에 부착 증식하는 호기성 미생물로 각종 유기물을 분해할 수 있으며, SS(Suspended Solids)를 포착할 수 있고, 질소를 효율적으로 제거할 수 있으며, 침전조(140) 내에서 인을 포함하는 침전 슬러지를 응집시켜 외부로 효과적으로 배출해 낼 수 있다. 더 나아가, 여재층(131)의 상부에 뿌리 발달 식물이 더 식재될 수 있고, 뿌리 발달 식물이 식재되는 경우, 수중 오염물질 중 특히 질소, 인, 중금속 등이 식물의 뿌리에서 흡착 및 흡수될 수 있고, 식물의 뿌리에서 증식하는 미생물에 의해 오염물질이 분해될 수 있다. In this way, various kinds of organic matter can be decomposed into aerobic microorganisms that adhere to and propagate on the surface of the filter medium while water passes through the filter medium in the filter medium layer 131, and it can capture SS (Suspended Solids) and efficiently nitrogen. It can be removed, and can be effectively discharged to the outside by flocculating the sludge containing phosphorus in the settling tank 140. Furthermore, the root development plant may be planted further on the upper layer 131, and when the root development plant is planted, nitrogen, phosphorus, heavy metals, etc., among water pollutants, may be adsorbed and absorbed at the root of the plant. And contaminants can be degraded by microorganisms that grow in the roots of plants.

먼저, 도 7 내지 도 9을 참조하면, 본 발명의 다른 실시예에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치는, 유입수를 저장하는 저장조(1110), 저장조(1110)로부터 월류시키거나 펌프(1112)를 통해 펌핑된 물을 유입시켜(펌핑관(1114)을 통해), 이로부터 오염물질을 침전시키는 유입조(1120), 및 유입조(1120)의 하부로부터 물을 유입시켜 상향류 및 하향류의 반복 흐름을 통해 호기성 미생물 및 혐기성 미생물로 1차로 수처리하는 제1 생물막 반응기(1130), 그리고, 제1 생물막 반응기(1130)의 하부에서 제1 생물막 반응기(1130)로부터 1차로 수처리된 물을 공급받아 상향류 및 하향류의 반복 흐름을 통해 2차로 수처리하는 제2 생물막 반응기(1140)를 포함한다. 따라서, 제1,2 생물막 반응기에서 하향류가 되면 공기가 유입되어, 호기상태를 유지하기 위해 별도의 송풍장치가 필요없다.First, referring to FIGS. 7 to 9, a biofilm water treatment apparatus having a non-powered backwashing function according to another embodiment of the present invention may be configured to overflow from a reservoir 1110 and a reservoir 1110 for storing inflow water or to pump 1112. Inflow of the pumped water through (through the pumping pipe 1114), the inflow tank 1120 for precipitating contaminants therefrom, and the inflow of water from the bottom of the inflow tank 1120 to the upstream and downstream of The first biofilm reactor 1130 for firstly treating the aerobic and anaerobic microorganisms through a repetitive flow, and receives the first water-treated water from the first biofilm reactor 1130 at the lower portion of the first biofilm reactor 1130. And a second biofilm reactor 1140 for secondary water treatment through repeated flows of upstream and downstream flows. Therefore, when the downflow in the first and second biofilm reactors, the air is introduced, there is no need for a separate blower to maintain the aerobic state.
제1 생물막 반응기(1130)는, 유입조(1120)로부터 유입되는 물을 여과 및 역세 과정을 통해 호기성 미생물 및 혐기성 미생물로 수처리하는 제1 담체층(1131a, 1131b, 이하 총괄하여 '1131'라 함)과, 제1 담체층(1131) 내에서 제1 배수관(1132)의 하단(bottom-end)이 제1 담체층(1131)의 하단보다 높게 위치하고 상부(11321)가 밀폐되고 하부(11322)가 개방되게 형성된 제1 배수관(1132)과, 제1 배수관(1132) 내에 삽입되고 상하부가 개방되고 하부가 제2 생물막 반응기(1140)로 연결되는 제2 배수관(1133)과, 유입조(1120)의 하부로부터 제1 담체층(1131)의 하부로 물을 공급하기 위한 유입로(1134)와, 유입로(1134)와 제1 담체층(1131) 사이에 위치하여 제1 담체층(1131)을 지지하고 유입로(1134)를 통해 유입되는 물을 통과시키는 제1 지지망(1135)과, 제1 지지망(1135)과 바닥 사이에서 제1 지지망(1135)을 지지하고 제1 지지망(1135)을 통해 하부로 배출되는 물을 제1 배수관(1132) 측으로 공급하기 위한 공간(11341;도 8 참조)을 형성하는 지지부재(1136)를 갖는다. 상기 공간(11341)은 유입로(1134)와 연결되도록 형성된다. 이와 같은 구성을 통해, 제1 담체층(1131)의 하부로부터 수위가 점차 높아져 제2 배수관(1133)의 상단의 높이(L1)보다 높아지는 경우, 제1 배수관(1132)의 내부 영역이면서 제2 배수관(1133)의 외부 영역으로 유입되는 물, 즉 제1 배수관(1132)과 제2 배수관(1133) 사이로 유입되는 물은, 제1 담체층(1131) 내의 수위가 제1 배수관(1132)의 하단의 높이(L5)와 대체로 동일하게 될 때까지 제2 배수관(1133)의 내부를 통해 제2 생물막 반응기(1140) 측으로 유출되어, 제1 담체층(1131)의 폐색 현상을 방지하도록 할 수 있다.The first biofilm reactor 1130 is a first carrier layer (1131a, 1131b, hereinafter collectively referred to as '1131') for treating water introduced from the inlet tank 1120 with aerobic and anaerobic microorganisms through filtration and backwashing. ) And the bottom-end of the first drain pipe 1132 is higher than the bottom of the first carrier layer 1131 in the first carrier layer 1131, and the upper part 1131 is sealed and the lower part 1122 is A first drain pipe 1132 formed to be open, a second drain pipe 1133 inserted into the first drain pipe 1132 and having an upper and lower portions open to the second biofilm reactor 1140, and an inlet tank 1120; An inlet path 1134 for supplying water from the lower part to the lower part of the first carrier layer 1131, and positioned between the inlet path 1134 and the first carrier layer 1131 to support the first carrier layer 1131. And a first support net 1135 for passing water introduced through the inlet path 1134, and a first support net 1135 between the first support net 1135 and the floor. Has a supporting member 1136 to form a, (see Fig. 8 11 341) and the space for supplying the water discharged from the lower portion on a first support network 1135 toward the first drain pipe 1132. The space 11341 is formed to be connected to the inflow path 1134. Through such a configuration, when the water level is gradually increased from the lower portion of the first carrier layer 1131 to be higher than the height L1 of the upper end of the second drain pipe 1133, the second drain pipe is an inner region of the first drain pipe 1132. The water flowing into the outer region of the 1113, that is, the water flowing between the first drain pipe 1132 and the second drain pipe 1133, has a water level in the lower end of the first drain pipe 1132. It may be discharged to the second biofilm reactor 1140 through the inside of the second drain pipe 1133 until the height L5 becomes substantially the same, thereby preventing the blocking of the first carrier layer 1131.
제1 배수관(1132)은 제1 담체층(1131) 내에 대체로 수직으로 관입되어 지지벽(1138)에 의해 고정될 수 있다. 도시하지는 않았으나, 예를 들어, 제1 배수관(1132)은 지지벽(1138)에 스크류나 기타 고정 수단을 통해 움직이지 않도록 지지벽(1138)과 이격되게 고정될 수 있다.The first drain pipe 1132 may be generally vertically introduced into the first carrier layer 1131 to be fixed by the support wall 1138. Although not shown, for example, the first drain pipe 1132 may be fixed to the support wall 1138 so as to be spaced apart from the support wall 1138 so as not to move through a screw or other fixing means.
지지벽(1138)은 제1 담체층(1131) 사이에서 제1 배수관(1132) 등이 관입될 수 있는 공간을 갖도록 형성되어 있는데, 이 지지벽(1138)은 제1 담체층(1131)과 제1 배수관(1132) 사이에서 제1 담체층(1131)에는 인접하도록 배치되고 제1 배수관(1132)과는 이격되도록 배치된다. 따라서, 제1 배수관(1132)과 지지벽(1138) 사이에는 외기가 유입될 수 있는 소정의 공간(1139)이 마련된다. 이 공간(1139)은, 앞서 설명된 동작 과정, 즉, 제1 담체층(1131)의 하부로부터 수위가 점차 높아져 제2 배수관(1133)의 상단의 높이(L1)보다 높아지는 경우, 제1 배수관(1132)의 내부 영역이면서 제2 배수관(1133)의 외부 영역으로 유입되는 물, 즉 제1 배수관(1132)과 제2 배수관(1133) 사이로 유입되는 물이, 제1 담체층(1131) 내의 수위가 제1 배수관(1132)의 하단의 높이(L5)와 대체로 동일하게 될 때까지 제2 배수관(1133)의 내부를 통해 제2 생물막 반응기(1140) 측으로 유출되는 동작 과정이 원활히 진행될 수 있도록 한다. 즉, 제1 담체층(1131) 내에서부터 공기가 유입될 수도 있지만 상기 공간(1139)을 통해 제2 배수관(1133)의 외부 영역으로 공기가 원활히 유입되면 제1 담체층(1131) 내의 수위 상부의 압력과 제2 배수관(1133)의 외부 영역에서의 압력이 동일하게 되어 제1 담체층(1131) 내의 수위가 제1 배수관(1132)의 하단보다 낮아지게 될 때 물의 유출이 중단된다.The support wall 1138 is formed to have a space in which the first drain pipe 1132 and the like can be inserted between the first carrier layer 1131. The support wall 1138 is formed of the first carrier layer 1131 and the first carrier layer 1131. Between the first drain pipe 1132, the first carrier layer 1131 is disposed to be adjacent to and spaced apart from the first drain pipe 1132. Therefore, a predetermined space 1139 through which external air can flow is provided between the first drain pipe 1132 and the support wall 1138. The space 1139 is the operation process described above, that is, when the water level is gradually increased from the lower portion of the first carrier layer 1131 and becomes higher than the height L1 of the upper end of the second drain pipe 1133, the first drain pipe ( Water flowing into the first drainage pipe 1132 and the second drainpipe 1133, that is, the water flowing into the first drainage pipe 1132 and the second drainpipe 1133, which is an inner region of the first drainage pipe 1333, The operation process flowing out to the second biofilm reactor 1140 through the interior of the second drain pipe 1133 until the height L5 of the lower end of the first drain pipe 1132 becomes substantially the same may be performed smoothly. That is, although air may flow in from the first carrier layer 1131, when air smoothly flows into the outer region of the second drain pipe 1133 through the space 1139, the upper portion of the water level in the first carrier layer 1131 may be increased. When the pressure is equal to the pressure in the outer region of the second drain pipe 1133 and the water level in the first carrier layer 1131 becomes lower than the lower end of the first drain pipe 1132, the outflow of water is stopped.
제1 담체층(1131)은 소정의 간격으로 대체로 수직 방향으로 배열되는 복수 개의 여과망들(1131a)과, 복수 개의 여과망들(1131a) 사이에 개재되는 접촉여재(1131b)를 포함한다. 도 9의 사시도에 도시된 바와 같이, 여과망들(1131a)은 소정의 간격으로 배치되고, 그 사이의 공간(1131b1)에 접촉여재(1131b)를 개재시킬 수 있다. 예를 들어, 접촉여재(1131b)는 섬유로 제작된 부직포 판 부재의 일종으로서 여과 효과를 갖는 사란 락(saran lock) 생물막 여재 또는 스펀지 등 재질의 담체일 수 있는데, 사란 락 또는 스펀지 등 재질의 담체와 같은 표면적을 극대화시킨 고정상 접촉여재를 통하여 중력에 의한 부유물질의 제거는 물론 여과에 의한 제거, 접촉여재에 부착하여 자라는 미생물에 의한 제거를 동시에 도모할 수 있고, 사란 락 또는 스펀지 등 재질의 담체는 교체 및 세척이 용이하다.The first carrier layer 1131 includes a plurality of filter nets 1131a arranged in a substantially vertical direction at predetermined intervals, and a contact medium 1131b interposed between the plurality of filter nets 1131a. As illustrated in the perspective view of FIG. 9, the filtering nets 1131a may be disposed at predetermined intervals, and the contact media 1113b may be interposed in the space 1131b1 therebetween. For example, the contact filter 1131b is a kind of nonwoven fabric member made of fiber, and may be a carrier of a material such as a saran lock biofilm media or a sponge having a filtration effect, and a carrier of a material such as saran lock or sponge. The fixed-phase contact media that maximizes the surface area, such as the removal of suspended solids by gravity as well as removal by filtration and microorganisms attached to the contact media, can be simultaneously promoted. Carriers of materials such as sarak rock or sponge It is easy to replace and wash.
제1 생물막 반응기(1130)에서, 제1 지지망(1135)을 통해 하부로 배출되는 물을 제1 배수관(1132) 측으로 공급하기 위한 공간(11341;도 8 참조)의 바닥(bottom) 중 일부 영역(예를 들어, 지지벽(1138)의 직하부)은, 제2 배수관(1133)이 관통하는 부분을 중심으로 하여 중심부분이 낮도록 경사지게 형성되어(11261) 배출되는 물 속의 침전 슬러지가 모이도록 할 수 있다. 침전된 슬러지는 별도의 슬러지 배출 수단(예컨대, 석션 펌프(suction pump)을 통해 외부로 배출될 수 있다(화살표 a11).In the first biofilm reactor 1130, a portion of the bottom of the bottom of the space 11341 (see FIG. 8) for supplying water discharged downward through the first support net 1135 to the side of the first drain pipe 1132 (see FIG. 8). For example, the lower portion of the support wall 1138) is formed to be inclined so that the center portion is low around the portion through which the second drain pipe 1133 penetrates (11261) to collect the settling sludge in the discharged water. Can be. The precipitated sludge may be discharged to the outside via a separate sludge discharge means (eg, suction pump) (arrow a11).
유입수를 저장하는 저장조(1110)는 전술한 바와 같이, 초기 우수, 하수, 중수 또는 하수 처리수 등의 유입수를 유입시킨다(화살표 a1). 도시되어 있지는 않으나, 저장조(1110) 내에는 유입수에서 오염물질을 침전시켜 침전 슬러지의 응집이 용이할 수 있도록 경사진 구조로 형성될 수 있다. 여기서 침전되는 오염물질은, 예를 들어, 조대 물질 또는 비교적 고 비중의 입자이다. 따라서, 이와 같은 고 비중의 입자는 1차적으로 유입조(1120) 이전 단계에서 저장조(1110)에서 침전된다. 저장조(1110)의 바닥에 침전된 슬러지는, 예를 들어, 별도로 설치된 석션 펌프(suction pump)(미도시)를 통해 외부로 배출될 수 있다. 저장조(1110) 내에는 유입조(1120) 내로 물을 펌핑할 수 있도록 저장조 펌프(1112)가 마련된다.As described above, the reservoir 1110 storing the inflow water introduces inflow water such as initial rainwater, sewage water, heavy water, or sewage treatment water (arrow a1). Although not shown, the storage tank 1110 may be formed in an inclined structure to precipitate the contaminants in the inflow water to facilitate the aggregation of the settling sludge. The pollutants precipitated here are, for example, coarse matter or particles of relatively high specific gravity. Therefore, such high specific gravity particles are primarily precipitated in the reservoir 1110 at the stage prior to the inlet tank 1120. The sludge deposited on the bottom of the reservoir 1110 may be discharged to the outside through, for example, a suction pump (not shown) installed separately. In the reservoir 1110, a reservoir pump 1112 is provided to pump water into the inlet 1120.
유입조(1120)는 저장조(1110)로부터 물을 월류시키거나 저장조 펌프(1112)를 이용하여 펌핑하여 유입시켜(화살표 a2) 이로부터 바닥(1126)에 오염물질을 침전시킴으로써 침전 슬러지를 생성한다. 또한, 유입조(1120)는 제2 생물막 반응기(1140)로부터 펌핑을 통해(화살표 a12) 물을 유입시킬 수 있다. 저장조(1110)로부터의 월류 또는 펌핑을 통한 물의 유입과 제2 생물막 반응기(1140)로부터의 물의 유입 동작은 서로 독립적이다. 즉, 유입조(1120)로 물을 유입함에 있어서, 저장조(1110)만으로부터 물을 유입시킬 수도 있고, 제2 생물막 반응기(1140)만로부터 펌핑을 통해 물을 유입시킬 수도 있으며, 둘 다로부터 동시에 유입시킬 수도 있다. 생성된 침전 슬러지는 비교적 고 비중의 오염물질로 이루어져 있다. 침전 슬러지는 석션 펌프(미도시)를 통해 외부로 배출된다(화살표 a3). 유입조(1120)는 유입되는 물(화살표 a2 또는 a12)로부터 오염물질을 침전시켜 침전 슬러지를 생성하기에 유리하도록 바닥부(1126)가 경사지게 형성되는 것이 바람직하다. 또한, 유입조(1120)는 침전된 오염물질 또는 침전 중에 있는 오염물질이 상 방향으로 역행하지 않도록 경사지게 배치된 경사판(1128)을 포함한다. 경사판(1128)은 도 7에 도시된 바와 같이, 서로 마주하는 유입조(1120)의 두 개의 측벽(11201, 11202)을 따라 길게 형성되어 있으며(도 9의 참조부호 1128 참조), 이 두 개의 측벽(11201, 11202)에서부터 중앙으로 뻗어나와 소정의 간격으로 교대로(alternately) 배치되며, 그 중앙이 주변보다 낮도록 경사지게 설치된다. 이러한 구조를 통해, 경사판(1128)은 아래로 내려간 오염물질이 다시 위로 상승하지 않도록 할 수 있다.The inlet 1120 overflows the water from the reservoir 1110 or pumps it in using a reservoir pump 1112 (arrow a2) to generate sedimentation sludge by depositing contaminants on the bottom 1126 therefrom. In addition, the inflow tank 1120 may introduce water from the second biofilm reactor 1140 through pumping (arrow a12). Inflow of water through the overflow or pumping from the reservoir 1110 and inflow of water from the second biofilm reactor 1140 are independent of each other. That is, in introducing water into the inflow tank 1120, water may be introduced only from the reservoir 1110, or water may be introduced through pumping from only the second biofilm reactor 1140, and both may simultaneously It can also be introduced. The precipitated sludge produced is composed of relatively high specific gravity pollutants. The settling sludge is discharged to the outside via a suction pump (not shown) (arrow a3). The inlet tank 1120 is preferably formed with the bottom portion 1126 inclined so as to advantageously precipitate contaminants from the incoming water (arrows a2 or a12) to produce settling sludge. In addition, the inflow tank 1120 includes an inclined plate 1128 disposed to be inclined so that the precipitated contaminants or the contaminants in the sedimentation do not return upward. As shown in FIG. 7, the inclined plate 1128 is elongated along two side walls 1121 and 11202 of the inflow tank 1120 facing each other (see reference numeral 1128 in FIG. 9). Extending from the centers 11201 and 11202, they are alternately arranged at predetermined intervals, and are installed to be inclined so that the center thereof is lower than the periphery. Through this structure, the inclined plate 1128 may prevent the contaminants falling down from rising upward again.
제2 생물막 반응기(1140)는, 제2 배수관(1133)으로부터 공급되는 물을 유도하는 유도관(1142)과, 유도관(1142)을 통해 유도된 물의 수위가 점차 높아지는 경우 미생물 접촉을 통해 오염물질을 처리하기 위한 제2 담체층(1141)과, 제2 담체층(1141)의 하부에서 제2 담체층(1141)을 지지하며 유도관(1142)을 통해 유도된 물을 통과시키는 제2 지지망(1143)과, 제2 지지망(1143)의 하부에서 물에 혼합된 오염물질이 통과하여 침전되도록 하는 침전 여과망(1144)과, 침전 여과망(1144)을 통과하여 침전된 오염물질에 의해 침전 슬러지가 생성되도록 경사지게 형성된 바닥부(1146)와, 제2 지지망(1143)의 하부에 위치하여 유입조(1120)로 물을 펌핑하기 위한 펌프(1122)를 포함한다. 펌프(1122)에서의 펌핑은, 제2 생물막 반응기(1140)에서 2차적으로 여과 및 역세 과정을 수행하기 위해 필요한 것으로서, 펌프(1122)에서의 펌핑으로 유입조(1120)로 물을 더 유입시켜 오염물질을 침전시킨다. 앞서 언급한 바와 같이, 펌프(1122)에서의 펌핑을 통해 유입조(1120)로 물을 유입시키는 과정은 저장조(1110)로부터의 물 유입 중이든 그렇지 않든 상관없이 진행될 수 있다.The second biofilm reactor 1140 is a conduit through microbial contact when the water level of the induction pipe 1142 for inducing water supplied from the second drain pipe 1133 and the water induced through the induction pipe 1142 is gradually increased. The second support layer (1141) and the second support network for supporting the second carrier layer (1141) in the lower portion of the second carrier layer (1141) for passing the water guided through the guide tube (1142) 1143), sediment filtering net 1144 for allowing the contaminants mixed with water to precipitate through the lower part of the second supporting net 1143, and sediment sludge is generated by the contaminant precipitated through the sediment filtering net 1144. A bottom portion 1146 is formed to be inclined as possible, and a pump 1122 for pumping water into the inlet 1120 is located below the second support net 1143. Pumping in the pump 1122 is necessary to perform the secondary filtration and backwashing process in the second biofilm reactor 1140, further pumping water into the inlet 1120 by pumping in the pump 1122 Precipitate contaminants. As mentioned above, the process of introducing water into the inlet 1120 through pumping at the pump 1122 may proceed regardless of whether or not water is being introduced from the reservoir 1110.
제2 담체층(1141)은 미생물 접촉을 위한 재료로서 담체를 포함하여, 유입된 물이 담체를 상하로 통과하면서 생물막 여과 작용을 한다. 여기서, 담체는 육면체 모양의 스펀지 담체 등의 기본형태가 적층되어 있을 수 있다.The second carrier layer 1141 includes a carrier as a material for contacting microorganisms, and performs biofilm filtration while the introduced water passes upward and downward through the carrier. Here, the carrier may be stacked in the basic form, such as a hexagonal sponge carrier.
제2 생물막 반응기(1140)의 바닥부(1146)에 침전된 슬러지는 외부에 설치된 석션 펌프(미도시)를 통해 외부로 배출될 수 있다(화살표 a4 참조). The sludge precipitated at the bottom 1146 of the second biofilm reactor 1140 may be discharged to the outside through an external suction pump (not shown) (see arrow a4).
본 발명의 다른 실시예에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치에서의 처리 단계를 전체적으로 살펴보면, 세 개의 단계로 구분해 볼 수 있다. 첫 번째 단계는, 조대 물질과 비교적 고비중 입자를 침전시켜서 제거하는 단계(유입조(1120)에서의 처리)이고, 두 번째 단계는, 상향류 및 하향류의 반복 흐름에 따라, 호기성 및 혐기성 미생물의 작용에 의해 오염물질 내의 각종 유기물을 분해하고, 질소/인 등을 제거하는 단계(제1 생물막 반응기(1130)에서의 처리)이며, 세 번째 단계는, 제2 배수관(1133)을 통해 유출되는 물을 여과 및 역세 과정에 따라 담체를 이용한 생물막 처리가 이루어지는 단계(제2 생물막 반응기(1140)에서의 처리)로 구분해 볼 수 있다.Looking at the treatment step in the biofilm water treatment device having a non-powered backwashing function according to another embodiment of the present invention, it can be divided into three steps. The first step is to settle and remove coarse material and relatively high specific gravity particles (treatment in inlet tank 1120), and the second step is aerobic and anaerobic microorganisms, with repeated flows of upstream and downstream flows. Decomposing various organic substances in the contaminants and removing nitrogen / phosphorus by the action of (processing in the first biofilm reactor 1130), and the third step is discharged through the second drain pipe 1133. Water may be classified into a step of performing a biofilm treatment using a carrier according to filtration and backwashing (treatment in the second biofilm reactor 1140).
두 번째 단계와 세 번째 단계를 구체적으로 살펴보도록 한다. 두 번째 단계, 즉 제1 생물막 반응기(1130)에서의 처리 과정을 살펴보면, 유입조(1120)에서 유입로(1134)를 통해 유입된 물의 수위가 점차 높아져서 대체로 L1 수위에 이르게 되는 경우, 물이 제2 배수관(1133)을 통해 하부로 배출된다. 이 때 빠른 유속에 따라 접촉여재(1131b)에 포착된 입자는 경사지게 형성된 바닥 중 일부 영역(11261)에 퇴적된다. 수위가 대체로 제1 배수관의 하단(11322), 즉 L5에 이르게 되면 제2 배수관(1133)을 통한 물의 배출은 중단되고 다시 수위가 높아진다. 수위가 높아지는 경우, 즉, 접촉여재(1131b)의 상부로 수조의 물이 상승하는 경우, 역세(back washing)가 이루어져 접촉여재(1131b)의 폐색을 방지하게 된다.Let's look at the second and third phases in detail. Looking at the second step, that is, the treatment process in the first biofilm reactor 1130, when the water level of the water introduced through the inlet 1134 in the inlet tank 1120 gradually increases to reach the L1 level, the water may be 2 is discharged downward through the drain pipe 1133. At this time, the particles trapped in the contact medium 1131b are deposited on the partial region 11261 of the bottom formed obliquely according to the high flow rate. When the water level reaches the lower end 1112 of the first drain pipe, that is, L5, the discharge of water through the second drain pipe 1133 is stopped and the water level is increased again. When the water level rises, that is, when the water in the tank rises to the upper portion of the contact medium 1131b, back washing is performed to prevent the contact medium 1113b from being blocked.
좀 더 구체적으로 설명하면, 제1 배수관(1132)과 제2 배수관(1133)은 서로 결합된 상태로 지지벽(1138) 내에 일정 간격(1139)을 두고 제1 담체층(1131) 내에 관입되는데, 제1 배수관(1132)의 상부(11321)는 밀폐되고 하부(11322)는 개방되도록 형성되는 반면, 제2 배수관(1133)의 상부와 하부는 개방되어 제2 생물막 반응기(1140)의 유도관(1142) 내로 물을 유입시킬 수 있다. 제1 배수관(1132)은 그 하단(bottom-end)(11322)이 제1 담체층(1131)의 하단보다 높게 위치한다. 도 7에 도시된 예에서 제1 배수관(1132)의 하단의 높이가 대체로 L5 라인과 유사하도록 설치되어 있다. 제2 배수관(1133)은 제1 배수관(1132) 내에 삽입되며, 그 상단의 높이는 제1 배수관(1132)의 상단(11321) 내부보다 낮다. 이하에서는, 제1 배수관(1132)과 제2 배수관(1133)의 이러한 결합 구조를 간단히 '배수관 결합구조'로 일컫는다. 제1 배수관(1132) 내에 제2 배수관(1133)이 삽입되어 있는 구조, 즉 배수관 결합 구조를 통한 처리 과정에서, 일단 제1 담체층(1131)의 하부에서부터 수위가 점차 높아지는 경우, 배수관 결합구조 내부, 즉 제1 배수관(1132)의 내부 영역이면서 제2 배수관(1133)의 외부 영역의 수위도 동일하게 높아진다. 계속해서 수위가 높아지다가, 수위가 제2 배수관(1133)의 상단보다 높아지는 경우, 제1 배수관(1132)의 내부 영역이면서 제2 배수관(1133)의 외부 영역으로 유입되는 물은 제2 배수관(1133)의 내부를 통해 제2 생물막 반응기(1140)의 유도관(1142)으로 유출되기 시작하고, 이러한 제2 배수관(1133)에서부터 유도관(1142)으로의 유출은 제1 담체층(1131) 내의 수위가 제1 배수관(1132)의 하단과 대체로 동일하게 될 때까지(즉, 수위가 L5로 될 때까지) 계속된다. 배수관 결합구조의 내부 압력과 관련하여 제2 생물막 반응기(1140) 측으로 물이 유출되는 과정을 간단히 살펴보면, 먼저 제2 배수관(1133)의 상단보다 수위가 높아지는 시점에 제2 배수관(1133)의 내부 영역을 통해(도 8의 화살표 a8) 물이 제2 생물막 반응기(1140) 측으로 일부 유출되고, 이와 동시에 제2 배수관(1133)과 제1 배수관(1132) 사이의 영역의 압력은 낮아지게 되고, 그 결과 그 낮아진 압력 하의 제2 배수관(1133)과 제1 배수관(1132) 사이의 영역으로 계속해서 물이 유입되어(도 8의 화살표 a6, a7) 그 영역으로 채워지게 되는데, 이러한 과정은 제1 담체층(1131) 내의 수위가 제1 배수관(1132)의 하단과 대체로 동일하게 될 때까지(즉, 수위가 L5로 될 때까지) 계속된다. 다시 말해, 물이 제2 배수관(1133)의 외부 영역과 내부 영역을 통해 유출되면 외부 영역과 내부 영역에서 공기가 제거되면서 제2 배수관(1133)의 외부 영역의 압력은 낮아지게 되고, 제1 담체층(1131) 내의 수위 상부의 압력과 제2 배수관(1133)의 외부 영역에서의 낮아진 압력 간의 차이로 인해 제1 담체층(1131)의 물은 제2 배수관(1133)의 외부 영역과 내부 영역을 통해 계속해서 유출되다가, 제2 배수관(1133)의 외부 영역으로 공기가 유입되기 시작하여 제1 담체층(1131) 내의 수위 상부의 압력과 제2 배수관(1133)의 외부 영역에서의 압력이 동일하게 되는 시점인, 제1 담체층(1131) 내의 수위가 제1 배수관(1132)의 하단보다 낮아지게 될 때 물의 유출이 중단된다.In more detail, the first drain pipe 1132 and the second drain pipe 1133 are introduced into the first carrier layer 1131 at a predetermined interval 1139 in the support wall 1138 while being coupled to each other. The upper part 1131 of the first drain pipe 1132 is sealed and the lower part 1112 is formed to be open, while the upper part and the lower part of the second drain pipe 1133 are opened to guide the induction pipe 1142 of the second biofilm reactor 1140. Water can be introduced into the The bottom of the first drain pipe 1132 is positioned higher than the bottom of the first carrier layer 1131. In the example shown in FIG. 7, the height of the lower end of the first drain pipe 1132 is substantially similar to the L5 line. The second drain pipe 1133 is inserted into the first drain pipe 1132, and the height of the upper end thereof is lower than the inside of the top 11321 of the first drain pipe 1132. Hereinafter, this coupling structure of the first drain pipe 1132 and the second drain pipe 1133 is simply referred to as a 'drain pipe coupling structure'. In the process in which the second drain pipe 1133 is inserted into the first drain pipe 1132, that is, through the drain pipe coupling structure, when the water level gradually increases from the lower portion of the first carrier layer 1131, the drain pipe coupling structure is inside. That is, the water level of the inner region of the first drain pipe 1132 and the outer region of the second drain pipe 1133 is equally high. If the water level is continuously increased and the water level is higher than the upper end of the second drain pipe 1133, the water flowing into the outer region of the second drain pipe 1133 while being the inner region of the first drain pipe 1132 is not the second drain pipe 1133. ) Flows into the induction pipe 1142 of the second biofilm reactor 1140, and the outflow from the second drain pipe 1133 to the induction pipe 1142 is increased in the first carrier layer 1131. Is continued to be approximately equal to the lower end of the first drain pipe 1132 (ie, the water level becomes L5). Briefly referring to the flow of water to the second biofilm reactor 1140 in relation to the internal pressure of the drain pipe coupling structure, first, the inner region of the second drain pipe 1133 when the water level is higher than the top of the second drain pipe 1133. Water (arrow a8 in FIG. 8) partially flows out toward the second biofilm reactor 1140, and at the same time the pressure in the region between the second drain pipe 1133 and the first drain pipe 1132 is lowered, and as a result Water continues to flow into the area between the second drain pipe 1133 and the first drain pipe 1132 under the lowered pressure (arrows a6 and a7 in FIG. 8) to fill the area, which is the first carrier layer. The water level in 1113 continues until substantially equal to the lower end of the first drain pipe 1132 (that is, until the water level becomes L5). In other words, when water flows out through the outer region and the inner region of the second drain pipe 1133, the air is removed from the outer region and the inner region, and the pressure in the outer region of the second drain tube 1133 is lowered. Due to the difference between the pressure above the water level in the layer 1131 and the lowered pressure in the outer region of the second drain 1113, the water of the first carrier layer 1131 causes the outer and inner regions of the second drain 1113 to dissipate. It continues to flow through, and air starts to flow into the outer region of the second drain pipe 1133 so that the pressure in the upper portion of the water level in the first carrier layer 1131 and the pressure in the outer region of the second drain pipe 1133 are the same. When the water level in the first carrier layer 1131 becomes lower than the lower end of the first drain pipe 1132, which is a point in time, the outflow of water is stopped.
제1 담체층(1131)의 하부에는, 제1 담체층(1131)을 지지하고 제1 담체층(1131)과 물 유입 공간(1134) 사이에서 물이 상하로 자유롭게 통과하도록 하는 제1 지지망(1135)이 더 구비되며, 제1 생물막 반응기(1130)의 바닥, 즉 물 유입 공간(1134)의 바닥과 제1 지지망(1135) 사이에서 제1 지지망(1135)을 지지하고 제1 지지망(1135)의 공극들 사이로 나오는 물을 제1 배수관(1132) 측, 즉, 배수관 결합구조 측으로 공급하기 위한 물 유입 공간(1134)이 형성되도록 하는 지지부재(1136)가 구비된다. 지지부재(1136)는 도 7 및 도 8에 예시된 바와 같이, 예를 들어, 단면적이 삼각형이고 폭이 좁으면서 긴 삼각 기둥 형상의 복수 개의 로드(rod)들이 소정 간격으로 길게 배열되어 제1 지지망(1135)을 아래에서 지지하면서 제1 지지망(1135)의 공극들 사이로 나오는 물을 배수관 결합구조 측으로 공급(도 8의 화살표 a6 및 a7 참조)하도록 구성될 수 있다. 도 7 및 도 8의 지지부재(1136)의 형상은 예시된 것에 불과하므로, 이러한 삼각기둥 형상의 로드들로 한정되는 것은 아니다.Under the first carrier layer 1131, a first support net 1135 supporting the first carrier layer 1131 and allowing water to pass freely up and down between the first carrier layer 1131 and the water inflow space 1134. ) Is further provided, supporting the first support net 1135 between the bottom of the first biofilm reactor 1130, that is, the bottom of the water inlet space 1134, and the first support net 1135 and the first support net 1135 of the first support net 1135. A support member 1136 is provided to form a water inflow space 1134 for supplying water flowing between the pores to the first drain pipe 1132, that is, the drain pipe coupling structure. As illustrated in FIGS. 7 and 8, the support member 1136 may include, for example, a plurality of rods having a triangular cross section and a narrow triangular column shape having a long triangular column shape and being arranged at predetermined intervals so as to have a first support net. It may be configured to supply water coming out between the pores of the first support net 1135 to the drain pipe coupling structure while supporting the 1135 from below (see arrows a6 and a7 in FIG. 8). Since the shape of the support member 1136 of FIGS. 7 and 8 is merely illustrated, the shape of the support member 1136 is not limited to the rods having a triangular prism shape.
이와 같이, 물의 유입 및 배출 과정에서 알 수 있는 바와 같이, 유입 및 배출 과정에서 L5를 기준으로 하여 그 아랫부분은 항상 물이 차 있는 상태로 유지되므로, L5의 윗 부분은 호기상이고 그 아랫 부분은 혐기상으로 볼 수 있다. 따라서, 접촉여재(1131b) 내에서 하향류와 상향류의 반복적인 흐름에 따라 호기성 미생물 및 혐기성 미생물의 작용에 의해, 오염물질 내에 포함된 암모니아성 질소(NH3-N)가 질산화 과정에 의해 질산성 질소(NO3-N)로 되고, 이후 아질산성 질소(NO2-N)로 된 후, 최종적으로 N2로 되는 탈질화 과정이 이루어질 수 있다. 대체로 오염물질 내의 질소 성분은 호기성 미생물에 의해 질산화되고, 혐기성 미생물에 탈질화된다.Thus, as can be seen in the inflow and outflow of water, the lower part of L5 is always filled with water in the inflow and outflow process, so the upper part of L5 is aerobic and the lower part thereof. Can be seen anaerobicly. Accordingly, ammonia nitrogen (NH 3 -N) contained in the contaminants may be removed by nitrification by the action of aerobic and anaerobic microorganisms under repeated flows of upstream and upstream in the contact medium 1131b. The denitrification process can be accomplished by acidic nitrogen (NO 3 -N), then by nitrous nitrogen (NO 2 -N), and finally by N 2 . As a rule, the nitrogen component in the contaminants is nitrified by aerobic microorganisms and denitrified by anaerobic microorganisms.
세 번째 단계에서는, 제2 배수관(1133)을 통해 물이 유입되는 경우, 유도관(1142)을 따라 제2 담체층(1141)의 하부로 유입된다. 유입된 물이 하부에서부터 차올라 그 수위가 상승 또는 유입조(1120)로 펌핑을 통해 그 수위가 하강하는 경우, 제2 담체층(1141)과 접촉 여과 및 산화(미생물 접촉에 의한 유기물 분해)된다. 이후, 수위가 높아져 후술할 오존 접촉조(1150)로 월류시킬 수 있고, 펌프(1122)를 이용하여 펌핑하여 유입조(1120) 내로 유입시킬 수 있다(화살표 a12 참조). 펌프(1122)를 이용하여 펌핑하는 경우 그 수위가 낮아지게 되는데, 이 때도 제2 담체층(1141)에 의한 생물막 처리가 이루어진다. 제2 담체층(1141)의 하부에는 제2 지지망(1143)이 설치되고, 최종적으로 그 하부에 침전 여과망(1144)이 설치되어, 오염물질이 바닥부(1146)에 침전되도록 한다. 침전 슬러지는 석션 펌프를 통해 외부로 배출된다(화살표 a4).In the third step, when water is introduced through the second drain pipe 1133, it is introduced into the lower portion of the second carrier layer 1141 along the induction pipe 1142. When the introduced water rises from the bottom and the water level rises or the water level decreases through pumping to the inflow tank 1120, the second carrier layer 1141 is subjected to contact filtration and oxidation (organic decomposition by microorganism contact). Thereafter, the water level may be increased to flow into the ozone contact tank 1150 to be described later, and may be pumped using the pump 1122 to be introduced into the inflow tank 1120 (see arrow a12). When the pump is pumped using the pump 1122, the water level is lowered. At this time, the biofilm treatment by the second carrier layer 1141 is performed. A second support net 1143 is installed at the bottom of the second carrier layer 1141, and a precipitation filter net 1144 is finally installed at the bottom of the second carrier layer 1141 to allow contaminants to settle on the bottom 1146. The settling sludge is discharged to the outside via the suction pump (arrow a4).
따라서, 제1,2 생물막 반응기에서 하향류가 되면 공기가 유입되어, 호기상태를 유지하기 위해 별도의 송풍장치가 필요없다.Therefore, when the downflow in the first and second biofilm reactors, the air is introduced, there is no need for a separate blower to maintain the aerobic state.
본 발명의 다른 실시예에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치는, 제2 생물막 반응기(1140) 이후의 수처리를 위해, 오존 접촉조(1150) 및 소독조(1160)를 더 포함할 수 있다. 오존 접촉조(1150)에서는 제2 생물막 반응기(1140) 내에서 오염물질이 침전된 후 월류하는 물을 산화 또는 탈색시키며, 소독조(1160)는 오존 접촉조(1150)에서의 처리 이후 물을 소독하기 위한 처리조이다. 여기서, 소독조(1160)에 염소 같은 소독약품을 주입하기 위한 소독약품 주입구가 별도로 마련될 수 있다. 소독조(1160) 내에는 소독 처리된 물을 외부로 배출(화살표 a5 참조)하여 사용할 수 있도록 소독조 펌프(1162)가 마련될 수 있다. 오존 접촉조(1150)에서 소독조(1160)로 물이 월류할 수 있도록 오존 접촉조(1150)와 제2 생물막 반응기(1140) 사이의 벽 높이(L3)보다 오존 접촉조(1150)와 소독조(1160) 사이의 벽 높이(L4)가 더 낮도록 설치된다.The biofilm water treatment apparatus having the non-powered backwashing function according to another embodiment of the present invention may further include an ozone contact tank 1150 and a disinfection tank 1160 for water treatment after the second biofilm reactor 1140. The ozone contact tank 1150 oxidizes or decolorizes the excess water after contaminants are precipitated in the second biofilm reactor 1140, and the disinfection tank 1160 disinfects the water after the treatment in the ozone contact tank 1150. It is a treatment tank for. In this case, a disinfectant injection hole for injecting a disinfectant such as chlorine into the disinfection tank 1160 may be separately provided. In the sterilization tank 1160, a sterilization pump 1116 may be provided to discharge the sterilized water to the outside (see arrow a5). The ozone contact tank 1150 and the disinfection tank 1160 are higher than the wall height L3 between the ozone contact tank 1150 and the second biofilm reactor 1140 so that water can flow from the ozone contact tank 1150 to the disinfection tank 1160. Wall height L4 between them is set lower.
이와 같이, 본 발명의 무동력 역세 기능을 갖는 생물막 수처리 장치의 다른 실시예는, 저장조(1110), 유입조(1120), 그리고 제1 생물막 반응기(1130)를 포함하는 상부층과, 제2 생물막 반응기(1140), 오존 접촉조(1150) 및 소독조(1160)를 포함하는 하부층으로 구분될 수 있는 간단한 처리 장치로 구현될 수 있어, 그 설치면에서도 편리한 이점이 있고, 역세를 위한 별도의 송풍기, 산기시설 등의 설비가 필요없어 비용면에서도 유리하고 에너지 절감 효과를 누릴 수 있다.As such, another embodiment of the biofilm water treatment apparatus having a non-powered backwashing function of the present invention includes an upper layer including a reservoir 1110, an inlet tank 1120, and a first biofilm reactor 1130, and a second biofilm reactor ( 1140, it can be implemented as a simple treatment device that can be divided into a lower layer including the ozone contact tank 1150 and the disinfection tank 1160, there is a convenient advantage in terms of its installation, and separate blower, air diffuser for backwash There is no need for such equipment, so it can be advantageous in terms of cost and save energy.
이하에서는 도 10을 도 7 내지 도 9과 함께 참조하여, 본 발명의 다른 실시예에 따른 무동력 역세 기능을 갖는 생물막 수처리 장치의 여과 및 역세 과정을 설명하도록 한다. 도 10에서 1차 생물막 처리로 나타낸 싸이클은 제1 생물막 반응기(1130)에서의 처리 과정이다.Hereinafter, the filtration and backwashing process of the biofilm water treatment apparatus having the non-powered backwashing function according to another embodiment of the present invention will be described with reference to FIGS. 10 to 7. The cycle shown as the primary biofilm treatment in FIG. 10 is a process in the first biofilm reactor 1130.
유입조(1120)로부터 유입로(1134)를 통해 제1 생물막 반응기(1130)의 하부로 물이 유입되고 수위가 점차 증가한다. 이때, 제1 생물막 반응기(1130)로 물과 함께 유입되는 오염물질은 물의 흐름(상향류)에 따라 제1 담체층(1131)으로 침투한다. 이후, 앞서 설명한 배수관 결합 구조의 동작에 의해, 물이 위에서 아래로 흐르는 하향류 흐름이 생기게 되는데, 이러한 상향류와 하향류 과정에서 물에 혼합된 오염물질, 예컨대, 유기물질, 미립자, 부유물질 및 중금속 등이 제1 담체층(1131)의 접촉여재(1131b)에 의해 여과 및 흡착되거나 유기물질이 제1 담체층(1131)에 존재하는 생물막에 의해 분해된다(도 7의 참조부호 ff 참조).Water is introduced into the lower portion of the first biofilm reactor 1130 through the inflow passage 1134 from the inflow tank 1120 and the water level gradually increases. At this time, contaminants introduced into the first biofilm reactor 1130 together with water penetrate into the first carrier layer 1131 according to the flow of water (upflow). Subsequently, the operation of the above-described drainage pipe coupling structure results in a downward flow in which water flows from the top to the bottom, and contaminants mixed with water in the upstream and downstream flows, for example, organic materials, particulates, suspended solids and Heavy metals and the like are filtered and adsorbed by the contact filter 1131b of the first carrier layer 1131, or the organic material is decomposed by the biofilm present in the first carrier layer 1131 (see reference numeral ff in FIG. 7).
이후, 수위가 대체로 L5에 이르게 되면, 더 이상의 배출은 일어나지 않고 유입되는 유입수에 의해 다시 수위가 높아진다. 이 경우, 제1 담체층(1131)을 기준으로 보면, 하부에서 상부로의 상향류 흐름이 생기는 것으로 볼 수 있는데, 제1 담체층(1131)의 하부에서부터 상부로의 상향류에 따라 진행되는 과정은 역세(back washing) 과정이다(도 7의 참조부호 bw 참조). 즉, 역세 과정은 제1 담체층(1131)의 하부에서 상부로의 물의 흐름에 따라 제1 담체층(1131) 내의 오염물질, 즉, 제1 담체층(1131) 내에서 접촉여재(1131b) 사이에 흡착되어 접촉여재(1131b)의 공극을 폐색하는 오염물질 또는 미생물 덩어리가 다시 상부로 이동하는 과정이다. 다시 말해, 이렇게 물의 흐름이 상향류와 하향류를 반복하여 흐름으로써 접촉여재 사이의 공극이 폐색되는 것을 방지한다. 여기서, 제1 담체층(1131)의 상부는 제1 담체층(1131) 중 대체로 제1 배수관(1132)의 하단보다 높은 부분으로서 비교적 산소가 많이 존재하는 호기상임에 비해(도 7의 참조부호 ae), 제1 담체층(1131)의 하부는 제1 담체층(1131) 중 대체로 제1 배수관(1132)의 하단보다 낮은 부분으로서 혐기상이다(도 7의 참조부호 an). 본 명세서 내에서 '대체로 제1 배수관(1132)의 높이'로 기술한 것은, 실제로 물의 기본적인 성질(표면 장력에서 기인한 성질 등)을 고려할 때, 제2 배수관(1133)에 의한 제2 생물막 반응기(1140)로의 배출시 제1 배수관(1132)의 하단과 정확히 일치하는 수위까지 배출되지는 않으므로, 이 점을 고려한 것이다.Thereafter, when the water level reaches approximately L5, no further discharge occurs and the water level is increased again by the incoming influent. In this case, when viewed based on the first carrier layer 1131, it can be seen that the upstream flow from the bottom to the top, the process that proceeds in accordance with the upward flow from the bottom of the first carrier layer 1131 to the top Is a back washing process (see reference numeral bw in FIG. 7). That is, the backwashing process is performed by the contaminants in the first carrier layer 1131, that is, between the contact media 1113b in the first carrier layer 1131 according to the flow of water from the bottom to the top of the first carrier layer 1131. It is a process in which a contaminant or microbial mass that is adsorbed on and occludes the pores of the contact media 1113b moves upwards again. In other words, the water flow is repeated in the upstream and the downstream to prevent the voids between the contact media from being blocked. Here, the upper portion of the first carrier layer 1131 is generally higher than the lower end of the first drain pipe 1132 of the first carrier layer 1131 as compared with the aerobic phase in which oxygen is present relatively (reference numeral ae in FIG. 7). ), The lower portion of the first carrier layer 1131 is anaerobic as the lower portion of the first carrier layer 1131 is generally lower than the lower end of the first drain pipe 1132 (reference numeral an in FIG. 7). In the present specification, the term 'usually the height of the first drain pipe 1132' refers to a second biofilm reactor by the second drain pipe 1133, considering the basic properties of water (such as due to surface tension). Since the discharge to the 1140 is not discharged to the water level exactly matching the lower end of the first drain pipe 1132, this point is considered.
제1 생물막 반응기(1130)에서의 여과 및 역세 과정에서 제1 생물막 반응기(1130)는, 여과 과정에서 제1 담체층의 상부에서 하부로 이동한 오염물질을 제1 담체층(1131) 내에서 호기성 미생물(aerobe, ae)로 처리한 후, 호기성 미생물의 하부에 존재하는 혐기성 미생물(anaerobe, an)로 처리하고, 혐기성 미생물로 처리한 후, 역세 과정에서 상향류(bw)에 따라 이동한 오염물질을 혐기성 미생물의 상부에 존재하는 호기성 미생물로 처리한다. 호기성 미생물에 의한 오염물질의 처리(S151) 과정에서 오염물질은 질산화된다. 그런 다음, 질산화 과정을 거친 오염물질은 하향류(ff)에 따라 아래로 이동하여 혐기상에 놓이게 된다. 여기서, 질산화 과정을 거친 오염물질은 혐기성 미생물에 의해 탈질화된다(S152). 하지만, 질산화 과정 및 탈질화 과정을 거치더라도 오염물질에서 완전히 질소가 제거된 상태는 아니다. 따라서, 그 상태의 오염물질은 역세 과정에서 상향류에 따라 위로 이동하여 다시 호기상에 놓이게 된다(S153). 여기서, 오염물질은 다시 질산화 과정을 거치게 되고, 이후 다시 하향류에 따라 혐기상으로 이동하여 혐기성 미생물에 의해 탈질화된다(S154). 이후, 물은 탈질화된 오염물질과 함께 제2 배수관(1133)의 내부를 통해, 제2 생물막 반응기(1140)의 유도관(1142)으로 유입되어, 제2 생물막 반응기(1140)에 의한 2차 생물막 처리가 수행된다(S155). 여기서, 여과 과정과 역세 과정, 즉 상향류 및 하향류에 따라 제1 담체층(1131) 내의 호기성 미생물 및 혐기성 미생물에 의한 반복적인 처리 과정은 효과적인 탈질화를 위해 수차례 반복될 수 있다.During the filtration and backwashing process in the first biofilm reactor 1130, the first biofilm reactor 1130 is aerobic in the first carrier layer 1131 for contaminants moved from the top to the bottom of the first carrier layer in the filtration process. After treatment with aerobe (ae), treated with anaerobic microorganisms (anaerobe, an) present in the lower part of the aerobic microorganisms, treated with anaerobic microorganisms, and then moved by upflow (bw) during backwashing Is treated with an aerobic microorganism present on top of the anaerobic microorganism. The pollutant is nitrified during the treatment of the pollutant by the aerobic microorganism (S151). The nitrified contaminants then move downward along the downflow (ff) and are placed in the anaerobic phase. Here, the contaminants that have undergone nitrification are denitrified by anaerobic microorganisms (S152). However, even after nitrification and denitrification, nitrogen is not completely removed from contaminants. Therefore, the contaminants in the state are moved upward according to the upstream in the backwashing process and placed on the exhalation again (S153). Here, the pollutant is subjected to nitrification again, and then moved back to the anaerobic phase according to the downflow again and denitrified by the anaerobic microorganism (S154). Thereafter, water is introduced into the induction pipe 1142 of the second biofilm reactor 1140 through the inside of the second drain pipe 1133 together with the denitrified contaminant, and the secondary water is discharged by the second biofilm reactor 1140. Biofilm treatment is performed (S155). Here, the repetitive treatment process by the aerobic microorganisms and anaerobic microorganisms in the first carrier layer 1131 according to the filtration process and the backwashing process, that is, upstream and downstream flows may be repeated several times for effective denitrification.
2차 생물막 처리(S155) 과정은 전술한 바와 같이, 유도관(1142)을 통한 물의 유입과 펌프(1122)에 의한 펌핑을 통한 배출에 의해 하향류 및 상향류의 반복적인 흐름이 생길 수 있고, 이에 따라 제2 담체층(1141)에서 여과와 미생물 접촉처리 및 여재폐색 방지가 이뤄질 수 있다.Secondary biofilm treatment (S155) process, as described above, by the inflow of water through the induction pipe 1142 and the discharge through the pumping by the pump 1122 may be a repetitive flow of downflow and upflow, Accordingly, filtration, microbial contact treatment, and blocking of media may be prevented in the second carrier layer 1141.
다음으로, 도 11을 참조하면, 먼저, 저장조(1110)의 펌프(1112) 및/또는 제2 생물막 반응기(1140)의 펌프(1122)에 의해 펌핑된 물이 유입조(1120) 내로 유입된다. 유입된 물은 유입조(1120) 내에서 침전 과정을 거치는데, 여기서 비교적 고 비중의 오염물질이 침전되고(S161), 바닥에 응집된 침전 슬러지는 별도의 석션 펌프를 통해 외부로 배출된다. 유입조(1120) 내로 물이 유입되는 경우, 제1 생물막 반응기(1130)의 아래에서부터 물이 차 올라서 수위가 증가하게 된다. 이후 수위가 계속해서 증가하다가 대체로 L1에 이르게 되는 경우, 제2 배수관(1133)을 통해 유출되는데, 이 때, 앞서 설명한 바와 같이 제1 담체층(1131)에서 생물막 여과가 이루어진다. 먼저 호기성 미생물에 의해 질산화가 진행되고(S162), 하향류에 따라 아래로 이동하여 혐기성 미생물에 의해 탈질화가 이루어진다(S163). 앞서 언급한 바와 같이, S162와 S163 과정은 수위가 높아지는 경우, 즉 상향류 흐름에 따라 S163 과정 이후 S162 과정 및 S163 과정이 반복되어 탈질 효율이 더욱 높아질 수 있다. 계속해서, 탈질 과정을 거친 이후 오염물질을 함유한 물은 제2 배수관(1133)을 통해 제2 생물막 반응기(1140)로 유입된다. 제2 생물막 반응기(1140)로 유입된 물은 제2 담체층(1141)에 의해 2차 생물막 처리가 이뤄진다(S164). 상향류 및 하향류에 따른 제2 담체층(1141) 내의 처리는 앞서 언급한 바와 같다. 이와 같이 하여, 물이 제1 담체층(1131) 및 제2 담체층(1141)을 통과하는 도중에, 여재의 표면에 부착 증식하는 미생물로 각종 유기물을 분해할 수 있으며, SS(Suspended Solids)를 포착할 수 있고, 질소 및 인을 효율적으로 제거할 수 있으며, 제1 여과망(1135), 제2 여과망(1143) 및 침전 여과망(1144) 구성을 통한 침전에 의해 침전 슬러지 형태로 효과적으로 외부로 배출해 낼 수 있다. 최종적으로, 오염물질이 제거된 유입수는 오존 접촉조(1150)와 소독조(1160)를 거쳐 방류된다(S165,S166). 한편, 물속의 인은 혐기조건하에서는 수중으로 배출되지만, 호기조건하에서는 호기성 미생물이 인을 섭취하고 있거나 인을 섭취한 미생물이 슬러지화되어 외부로 방출되게 된다.Next, referring to FIG. 11, first, water pumped by the pump 1112 of the reservoir 1110 and / or the pump 1122 of the second biofilm reactor 1140 is introduced into the inlet 1120. The introduced water is subjected to the precipitation process in the inflow tank 1120, where a relatively high specific gravity of the contaminants is precipitated (S161), the sedimentation sludge aggregated on the bottom is discharged to the outside through a separate suction pump. When water is introduced into the inlet tank 1120, the water rises from the bottom of the first biofilm reactor 1130, thereby increasing the water level. If the water level continues to increase and then reaches approximately L1, it flows out through the second drain pipe 1133. At this time, biofilm filtration is performed in the first carrier layer 1131 as described above. First, nitrification proceeds by the aerobic microorganism (S162), and is moved downward according to the downflow to denitrification by the anaerobic microorganism (S163). As mentioned above, when the water level is increased, that is, the process S162 and S163 are repeated after the process S163 according to the upstream flow, the denitrification efficiency may be further increased. Subsequently, after the denitrification process, the water containing the contaminant is introduced into the second biofilm reactor 1140 through the second drain pipe 1133. Water introduced into the second biofilm reactor 1140 is subjected to the second biofilm treatment by the second carrier layer 1141 (S164). The treatment in the second carrier layer 1141 according to the upflow and the downflow is as described above. In this way, while the water passes through the first carrier layer 1131 and the second carrier layer 1141, various organic substances can be decomposed into microorganisms that adhere to and propagate on the surface of the media, and SS (Suspended Solids) are captured. It is possible to efficiently remove nitrogen and phosphorus, and can be effectively discharged to the outside in the form of sediment sludge by precipitation through the configuration of the first filter net 1135, the second filter net 1143 and the precipitation filter net 1144. have. Finally, the influent water from which the contaminants have been removed is discharged through the ozone contact tank 1150 and the disinfection tank 1160 (S165 and S166). On the other hand, phosphorus in the water is discharged into the water under anaerobic conditions, but under aerobic conditions, aerobic microorganisms are ingesting phosphorus or microorganisms ingesting phosphorus are sludged and released to the outside.

In addition, contaminants can be utilized as nutrients for plants, and contaminants can be decomposed through the biofilm of adherent microorganisms without introducing a separate power, and clogging in the filtration layer due to the repeated action of downflow and upflow.
