종래의 기술은 생물반응조(폭기조)와 침전조를 두고 폭기조 전단 및 후단에 무산소탈질조를 두어 A/O 또는 A2/O방법으로 질소와 인 제거를 유도하였으며, 또한 기존의 탈질조의 구조는 상부에서 주입하고 전면을 통하여 하부로 흐름을 형성하여 혼합 충진물에 접촉을 하여 탈질반응이 일어나고 하부의 유출구로 유출되는 구조로 되어 있어, 그 처리효율이 좋지 못한 단점을 갖고 있다.The prior art has a bioreactor (aeration tank) and a settling tank, an anoxic denitrification tank at the front and rear of the aeration tank to induce nitrogen and phosphorus removal by A / O or A 2 / O method, and the structure of the conventional denitrification tank at the top Injecting and forming a flow through the front to the bottom to contact the mixed filling, the denitrification reaction occurs and the structure is discharged to the outlet of the lower, there is a disadvantage that the treatment efficiency is not good.
상기와 같은 문제점을 해결하기 위해 본 고안은 수중의 질산성질소를 효과적으로 제거하기 위하여 2가지 단계를 거치는 것으로, 1단계에서는 오·폐수를 충분히 산화하여 유기물의 제거와 질산화를 유도하여 분리막을 통하여 부유성고형물질(SS)성분의 90%이상을 걸러주게 되고, 2단계의 황산화 탈질에서는 미량의 부유성고형물(Suspended Solids;SS)성분으로 황담체의 막힘과 FOULING을 없애 줌으로써, 독립영양 탈질공여체인 황(S)과 접촉기회를 많게 함으로 제거효율이 높아지고, 3단 원통형구조로써, 반응시간이 길어지고, 미량의 슬러지생성으로 역세주기를 길게 주거나 역세장치를 생략할 수 있으므로, 담체의 수명이 길어지고, 운전비용을 절감할 수 있는 오·폐수의 유기물 및 질소 제거장치를 제공하고자 한다.In order to solve the above problems, the present invention goes through two steps to effectively remove nitrate nitrogen from the water. In the first step, the wastewater is sufficiently oxidized to induce organic matter removal and nitrification, and thus, through the separator. It filters over 90% of the solid component (SS), and in the two-sulfation denitrification, it is a small amount of suspended solids (SS) that eliminates the blockage and FOULING of the yellow carrier, and thus is an independent nutrient denitrification donor. The removal efficiency is increased by increasing the contact opportunity with phosphorus (S), the three-stage cylindrical structure, the reaction time is long, and the backwash cycle can be lengthened by the generation of trace sludge or the backwashing device can be omitted, so the life of the carrier is long. The present invention aims to provide a device for removing organic matter and nitrogen from wastewater, which can be lengthened and reduce operating costs.

외통(51)의 내측상단 외둘레로 형성된 월류웨어(54)가 구성되어 있는 것을 특징으로 한다.It is characterized in that the overflow wear 54 is formed in the inner upper outer circumference of the outer cylinder (51).
상기 장치적 구성에 따른 본 고안의 오·폐수의 처리과정을 상세하게 살펴보면,Looking at the treatment process of the waste water of the present invention according to the device configuration in detail,
유량조정조(1)는 유입 오·폐수의 유량과 수질의 변동을 흡수해서 처리시설의 처리효율을 높이고 처리수질의 향상을 위해 설치하는 것으로써, 저부에는 블로어를 통해 공급되는 공기를 오·폐수에 공급하는 산기관이 설치되어 있다.The flow rate adjusting tank 1 is installed to absorb the fluctuations in the inflow and wastewater flow rate and the water quality to increase the treatment efficiency of the treatment facility and to improve the treatment water quality. Supply diffuser is installed.
제1폭기조(2)는 유량조정조(1) 내측 저부에 설치되어 있는 펌프를 통해 유입되는 오·폐수와 제2폭기조(3)로부터 반송되는 오·폐수를 수용하여 제1폭기조(2) 저부에 설치되어 있는 산기관을 통해 호기성 미생물에 산소를 공급하고, 호기성 미생물에 의해 수중의 유기물이 분해된다. 용존산소 농도의 유지를 위한 조절은 폭기조내 1.5 ~ 4.0mg/L농도로 유지될 수 있도록 하여야 하며, 과잉폭기는 큰 전단력을 일으켜 미생물 floc의 형성을 방해하고 응결입자를 깨뜨리기도 한다. 또한 폭기 시간이 길면 전단력에 의해 응결입자는 파괴되어 다량의 미생물 조각들로 분리되어 침전성이 불량해진다. The 1st aeration tank 2 accommodates the wastewater which flows in through the pump provided in the bottom part of the flow control tank 1, and the wastewater conveyed from the 2nd aeration tank 3, and it is located in the bottom of the 1st aeration tank 2 Oxygen is supplied to the aerobic microorganisms through the diffuser, and organic matter in the water is decomposed by the aerobic microorganisms. Control to maintain dissolved oxygen concentrations should be maintained at a concentration of 1.5 to 4.0 mg / L in the aeration tank. Excessive aeration can cause large shear forces, disrupting microbial floc formation and breaking condensation particles. In addition, when the aeration time is long, the condensation particles are broken by the shear force and are separated into a large amount of microbial fragments, resulting in poor precipitation.
이와 같이 고형물체류시간(SRT)가 길어짐으로써 발생되는 문제를 방지하기 위해 제2폭기조(3)의 내부에는 침지형분리막(32)이 설치되고, 침지형분리막(32)을 통하여 유기물제거와 질산화가 일어나게 된다.In order to prevent the problem caused by the long solid SRT, an immersion type separation membrane 32 is installed inside the second aeration tank 3, and organic matter removal and nitrification occur through the immersion type separation membrane 32. .
이상에서와 같이 유량조정조(1), 제1폭기조(2) 및 제2폭기조(3)는 본 고안에서 1단계처리 장치에 관한 것으로, 1단계처리를 통해 유입된 오·폐수내 유기물제거와 질산화가 일어나게 된다.As described above, the flow rate adjusting tank 1, the first aeration tank 2 and the second aeration tank 3 are related to the one-stage treatment apparatus in the present invention, and organic matter removal and nitrification in the wastewater introduced through the one-stage treatment. Will happen.
유기물제거와 질산화가 일어난, 1단계처리된 오·폐수는 침지형분리막(32)에서 탈질조주입펌프(41)를 통해 혼합충진탈질조(7)로 압송된다.The wastewater treated in one step, in which organic matters are removed and nitrified, is sent to the mixed filling denitrification tank 7 through the denitrification tank injection pump 41 from the immersion type separation membrane 32.
혼합충진탈질조(7)로 압송된 오·폐수는 황탈질의 기능을 우수하게 수행하기 위하여 혼합충진탈질조(7)의 접촉시간을 길게 주게 하기 위하여 3단 원통형구조로 하고 내통은 상향류(UP-FLOW)흐름을 유지하고, 중간통(52)은 하향류(DOWN-FLOW)를 유지하며, 외통(51)은 상향류(UP-FLOW)흐름을 채택하여 폐수를 황혼합충진물에 접촉할 수 있는 확률을 극대화하여 처리한다.The wastewater pumped into the mixed filling denitrification tank (7) has a three-stage cylindrical structure in order to lengthen the contact time of the mixed filling denitrification tank (7) in order to perform the function of the denitrification well. UP-FLOW flow, the intermediate barrel 52 maintains DOWN-FLOW, and the outer cylinder 51 adopts UP-FLOW flow to contact the wastewater with the twilight filler. Maximize the chances that can be handled.
또한, 본 고안에 따른 3단 원통형구조는 홀수단으로 구성하여 충분히 변경설계가 가능함을 밝혀두는 바이다.In addition, the three-stage cylindrical structure according to the present invention is configured to be a hole means that it is possible to change the design sufficiently.
상기 혼합충진탈질조(7)의 장치적 구성에 따른 오·폐수의 처리과정을 살펴보면, 도5에 도시된 바와 같이, 유입관(56)을 통해 유입된 오·폐수는 유입분사관(57)을 거쳐 충진물지지대(58)의 내측하부를 통과하여 내통(53)의 외둘레에 의해 형성된 내측관(531)으로 유입되고, 유입된 오·폐수는 상향류 흐름을 유지한다.Looking at the waste water treatment process according to the device configuration of the mixed filling denitrification tank (7), as shown in Figure 5, the waste water introduced through the inlet pipe 56 is the inlet injection pipe 57 Passing through the inner lower portion of the filler support 58 is introduced into the inner tube 531 formed by the outer circumference of the inner cylinder 53, the introduced waste water maintains the upflow flow.
중간통(52)보다 높이가 낮게 형성된 내통(53)의 내측관(531)을 거친 폐수는 내통(53)을 넘쳐 흘러, 내통(53)과 중간통(52)사이에 형성된 중간측관(521)을 타고 하향류 흐름을 유지한다.Wastewater passing through the inner tube 531 of the inner cylinder 53 formed lower than the intermediate cylinder 52 flows over the inner cylinder 53, and the intermediate side pipe 521 formed between the inner cylinder 53 and the intermediate cylinder 52 is formed. To keep the flow down.
중간측관(521)을 거친 오·폐수는 중간통(52)과 충진물지지대(58) 사이가 일정간격 이격되어 형성된 빈 공간을 통해, 중간통(52)과 외통(51)사이에 형성된 외측관(511)으로 흘러들어 상향류 흐름을 유지한다. 외측관(511)을 통해 최종처리된 오·폐수는 월류웨어(54)을 넘어 배출관(59)을 통해 외부로 배출된다.Waste water passing through the intermediate tube 521 is an outer tube formed between the intermediate cylinder 52 and the outer cylinder 51 through an empty space formed between the intermediate cylinder 52 and the filler support 58 at a predetermined interval. 511) to maintain the upflow flow. The wastewater finally treated through the outer pipe 511 is discharged to the outside through the discharge pipe 59 beyond the overflowware 54.
이때 오·폐수는 내측관(531), 중간측관(521) 및 외측관(511) 내부에 충진되어 있는 황혼합충진물(55)을 거치면서 탈질처리가 되며, 상기 황혼합충진물(55)은 황(S) 30 ~ 50중량%과 석회석(limestone) 또는 인회석(apatite) 중 선택되는 1종 50 ~ 70중량%를 혼합하여 사용한다.At this time, the waste water is denitrified while passing through the twilight coal filler 55 which is filled in the inner tube 531, the intermediate tube 521 and the outer tube 511, and the twilight coal filler 55 is sulfur (S) 30 to 50% by weight and one type of 50 to 70% by weight selected from limestone (limestone) or apatite (apatite) is used in combination.
이와 같이, 1단계처리된 오·폐수는 황과 석회석 또는 인회석이 혼합충진된 탈질조에서 2단계처리되어 탈질처리된다.As such, the wastewater treated in one step is denitrified by two steps in a denitrification tank mixed with sulfur and limestone or apatite.
이상에서 살펴본 오·폐수처리과정에 따른 반응을 살펴보면,Looking at the reaction according to the waste water treatment process described above,
제2폭기조(3) 내부에 침지되어 있는 침지형분리막(32)을 통과한 오·폐수는 유기물의 대부분이 제거됨과 동시에 암모늄염(NH4 +)과 암모니아성질소(NH3-N)등의 질소성분은 질산화과정을 거쳐 질산성질소(NO3-N)로 산화되고, 부유성고형물(Suspended Solids;SS)성분은 5ppm이하로 되어 혼합충진탈질조(7)로 유입하게 된다. 하수나 오수의 경우 질산화과정이 진행되며 총질소(T-N)는 20 ~ 30ppm정도 존재하고 질산성질소(NO3-N)는 이중 90%정도 차지하게 되는데 약 15 ~ 20ppm을 차지하고 있다. 이를 황혼합충진물(55)과 접촉시키면 1몰의 질산성질소(NO3-N)와 1.1몰의 황(S)은 0.5몰의 질소가스(N2)와 1.1몰의 황산염(SO4 2)을 생성하고 0.08몰의 황탈질 미생물이 합성된다.Wastewater that has passed through the immersion membrane 32 immersed in the second aeration tank 3 is removed with most of organic matter and nitrogen components such as ammonium salt (NH 4 + ) and ammonia nitrogen (NH 3 -N). Is oxidized to nitric nitrate (NO 3 -N) through the nitrification process, the suspended solids (SS) is less than 5ppm flow into the mixed packed denitrification tank (7). In the case of sewage or sewage, nitrification proceeds, and total nitrogen (TN) is present in the range of 20 to 30ppm, and nitric acid (NO 3 -N) accounts for about 90%, accounting for about 15 to 20ppm. When it is brought into contact with the twilight filler 55, one mole of nitrogen nitrate (NO 3 -N) and 1.1 mole of sulfur (S) are 0.5 mole of nitrogen gas (N 2 ) and 1.1 mole of sulfate (SO 4 2 ). And 0.08 moles of denitrifying microorganisms are synthesized.

이상에서 살펴본 바와 같이, 본 고안은 침지형분리막(MBR)공정과 황산화탈질공정을 복합한 것으로 침지형분리막(MBR)공정의 처리수를 황산화탈질공정에 주입함으로서 질소제거에 탁월한 효과가 있으며, 전단계인 침지형분리막공정도 황산화탈질공정의 슬러지 유입의 최소화 및 담체의 막힘방지등을 이행함으로 상호보완적인 기능이 있으며, 황산화탈질공정 내부를 3단 원통형 구조로 함으로써 체류시간과 접촉시간을 길게 주어 처리효율을 극대화하여 비용이 절감되고 안정적인 운전이 가능한 효과를 갖는다.As described above, the present invention is a combination of an immersion type separation membrane (MBR) process and a sulphate denitrification process, and has an excellent effect on nitrogen removal by injecting the treated water of the immersion type separation membrane (MBR) process into a sulphation denitrification process. Phosphorus-immersed membrane process also has a complementary function by minimizing sludge inflow from sulfidation denitrification process and preventing clogging of carriers. It maximizes the processing efficiency and reduces the cost and has the effect of stable operation.
