Description

공공하수 및 공장폐수용 폐수처리장치 {WASTE WATER DISPOSAL FOR PUBLIC SEWAGE AND FACTORY WASTES}Wastewater treatment system for public sewage and factory wastewater {WASTE WATER DISPOSAL FOR PUBLIC SEWAGE AND FACTORY WASTES}

본 발명은 공공하수 및 공장폐수용 폐수처리장치에 관한 것으로서, 보다 상세하게는, 공공하수 및 공장폐수에 함유된 유기물과 칼슘이온 등 경도유발물질을 경제적으로 제거하여 공정수로 재사용하고, 응집제와 폐수의 접촉시간을 증가시켜 효과적인 반응이 일어날 수 있도록 하는 공장폐수 및 공공폐수처리장치에 관한 것이다.
The present invention relates to a wastewater treatment apparatus for public sewage and plant wastewater, and more specifically, to remove organically and mildly induced materials such as calcium ions contained in public sewage and plant wastewater economically and reuse them as process water, The present invention relates to a plant wastewater and public wastewater treatment device that increases the contact time of wastewater so that an effective reaction can occur.

일반적인 오염수의 정화처리나 생활용수의 정수처리 시에 물의 혐기화를 방지하고 오염성분을 산화시키는 등 용존산소량을 증가 내지 포화시킨 다음 다른 연장상의 화학적, 생물학적, 물리적 처리의 효과를 증대시키기 위해 수중 폭기기법을 사용하고 있다.Increase or saturate dissolved oxygen such as to prevent anaerobicization of water and to oxidize contaminants during general contaminated water purification or purified water treatment, and to increase the effects of chemical, biological and physical treatments on other extensions. Aeration method is used.

그러나 기존의 폭기기법은 처리장의 공기를 처리대상수에 폭기하고 있으나 여러 가지 난점과 악조건으로 그 실효를 거두지 못하고 있는 실정이다.However, the existing aeration method aerated the air of the treatment plant to the treated water, but the situation is not effective due to various difficulties and bad conditions.

그 이유로는 공기를 수중 폭기할 경우 물과 공기의 밀도차이와 비중차이로 인해 폭기된 공기는 수면을 향해 급부상하게 되므로 물과 공기의 교류시간이 극히 짧아 그 실효를 거두지 못함이 결정적이며 폐수의 특성상 착이온이 강하여 안정화되어 있고 물과 오염성분간 해리 엔탈피가 낮으며 원소간의 전기음성도가 커서 물과 오염성분의 결합력이 강하고 분자운동이 매우 둔한 상태의 오염수에 일방적인 폭기만으로는 사실상 효과적인 성과를 얻기는 어렵다.The reason for this is that when aeration of water is carried out underwater, the aeration of air due to the difference in density and specific gravity of water and air suddenly rises toward the surface, so the exchange time between water and air is extremely short, and its effectiveness is decisive. Strong complex ion, stable dissociation, low dissociation enthalpy between water and contaminants, high electronegativity between elements, strong binding force between water and contaminants, and effective one-way aeration for contaminated water with very low molecular motion. Is difficult.

특히 도회지 주변의 공기는 매우 오염되어 있고 이 오염된 공기에 폐수에서 기화상승하는 여러 오염성분이 그 오염을 악화시키고 있는 실정이며 이러한 상태의 오염이 극심한 공기를 오염수속에 폭기하는 것이 현재 대다수 오염처리장의 실정이고 이러한 상태로는 실효를 거둘 수 없고 어떠한 경우에도 재오염을 유발할 수도 있다.
In particular, the air around the town is very polluted, and many pollutants that evaporate from the waste water exacerbate the pollution. This condition is not effective and may cause recontamination in any case.

도 1 내지 도 3을 참조하면, 본 발명의 일 실시예에 따른 공공하수 및 공장폐수용 폐수처리장치는, 혐기성 미생물에 의해 유기물을 이산화탄소와 메탄가스로 분해하고, 황환원균에 의해 황산이온을 황화수소로 환원시켜 제거하는 혐기성 반응조(1)와, 혐기성 반응조(1)로부터 공급되는 폐수를 낙하시켜 이산화탄소를 탈기시키고, 응집제를 공급하여 경도유발물질을 불용성 고형물로 전환시켜 제거하는 경도유발물질 제거부(10)와, 경도유발물질 제거부(10)로부터 공급되는 폐수로부터 슬러지를 제거하는 부유물 제거조(90)를 포함하고, 경도유발물질 제거부(10)는, 혐기성 반응조(1)로부터 공급되는 폐수가 담수되는 담수부(12)와, 담수부(12)로부터 흘러넘치는 폐수가 단계적으로 흐르도록 계단 모양으로 형성되는 배출부(70)와, 담수부(12)에 폐수를 공급하는 제1공급관(30)과, 제1공급관(30) 내부에 설치되고, 폐수와 혼합되는 응집제를 공급하는 제2공급관(50)과, 제2공급관(50)으로부터 배출되는 응집제를 유동시켜 제1공급관(30)으로부터 배출되는 폐수와 응집제를 혼합시키는 혼합부(80)를 포함한다.1 to 3, wastewater treatment apparatus for public sewage and factory wastewater according to an embodiment of the present invention, the organic matter is decomposed into carbon dioxide and methane gas by anaerobic microorganisms, sulfuric acid ion by sulfur reduction bacteria Anaerobic reactor (1) to reduce and remove hydrogen sulfide, and the waste water supplied from the anaerobic reactor (1) to drop the carbon dioxide by degassing, supplying a flocculant to convert the hardness-inducing material to insoluble solids to remove (10) and a float removal tank (90) for removing sludge from the wastewater supplied from the hardness-induced substance removal unit (10), wherein the hardness-induced substance removal unit (10) is supplied from the anaerobic reaction tank (1). Supplying wastewater to the freshwater part 12 to which the wastewater flows, the discharge part 70 formed in the step shape so that the wastewater which flows from the freshwater part 12 flows in steps, and the freshwater part 12 The first supply pipe 30 flows through the first supply pipe 30, the second supply pipe 50 installed in the first supply pipe 30, and supplies the coagulant mixed with the wastewater, and the coagulant discharged from the second supply pipe 50. And a mixing section 80 for mixing the wastewater discharged from the 30 with the flocculant.

혐기성 반응조(1)에서는 유기물이 이산화탄소와 메탄가스로 분해되고, 황산이온이 황화수소로 환원되어 제거되는데, 혐기성 반응조(1)로는 일반적으로 사용되는 혐기성 반응조(1) 외에 입상 슬러지를 사용하는 상향류식 혐기성 반응조(1)(UASB: up-flow anaerobic sludge blanket)나 담체를 이용하여 혐기성 미생물을 부착시켜 제거하는 반응조(AF:anaerobic filter) 등을 사용할 수 있다.In the anaerobic reactor (1), organic matter is decomposed into carbon dioxide and methane gas, and sulfuric acid ions are reduced and removed by hydrogen sulfide. The anaerobic reactor (1) is an upflow anaerobic reactor using granular sludge in addition to the anaerobic reactor (1). A reactor (AF: anaerobic filter) for attaching and removing anaerobic microorganisms by using a reactor (UASB: up-flow anaerobic sludge blanket) or a carrier may be used.

이산화탄소는 혐기성 반응조(1)에서 생성되는 바이오가스의 40% 정도를 차지하며 0.4 기압 정도의 분압을 가지는 이산화탄소는 많은 양이 처리수에 용해되어 이산화탄소와 중탄산이온의 형태로 존재하게 된다.Carbon dioxide occupies about 40% of the biogas produced in the anaerobic reactor 1, and carbon dioxide having a partial pressure of about 0.4 atm is dissolved in the treated water and exists in the form of carbon dioxide and bicarbonate ions.

경도유발물질 제거부(10)에서는 물에서 이산화탄소가 제거되어 pH가 높아지고, pH 8 이상에서 중탄산이온이 탄산이온으로 전환되는 현상에 의해 탄산이온이 생성되어 칼슘이온과 반응됨으로써 탄산칼슘으로 전환되어 제거된다.In the mildly-induced substance removing unit 10, carbon dioxide is removed from the water to increase the pH, and bicarbonate ions are converted to carbonate ions at pH 8 or higher, thereby producing carbonate ions and reacting with calcium ions, thereby converting them to calcium carbonate and removing them. do.

본 실시예는, 위치에너지를 이용하여 탈기시켜 경도유발물질을 불용성 고형물로 전환시키게 된다.In this embodiment, the potential energy is degassed to convert the hardness-inducing substance into an insoluble solid.

생성되는 고형물을 제거하는 방법은, 플라스틱이나 세라믹 등 소재로 이루어지는 여재의 표면이나 탄산칼슘 결정을 핵으로 하여 결정화시켜 제거한다.In the method of removing the produced solids, crystallization is performed by using the surface of a filter medium made of a material such as plastic or ceramics or a calcium carbonate crystal as a nucleus.

상기한 공정에 의해 경도유발물질의 30~90%가 고형물의 형태로 제거되므로 응집제의 사용량과 장치의 규모와 최종 슬러지 처리비용이 줄어들게 된다.By the above process, 30 to 90% of the hardness-induced material is removed in the form of a solid, thereby reducing the amount of flocculant used, the size of the apparatus, and the final sludge treatment cost.

위치 에너지를 이용하여 탈기시키면서 불용성 결정을 석출하는 방법은, 혐기성 반응조에서 공급되는 유출수를 제1공급관(30)을 따라 낙하시킴으로써 싸이프닝을 일으켜 탈기시킨 후에, 계단식으로 형성되는 배출부(70)를 따라 흘러내리면서 여재에 불용성 결정이 석출되도록 한다.The method of depositing insoluble crystals by degassing using potential energy is to drop outflow water supplied from the anaerobic reactor along the first supply pipe 30 to cause degassing and degassing. As it flows down, it causes insoluble crystals to precipitate in the media.

탈기공정에 앞서 혹은 호기성 탈기단계의 앞이나 중간단계에서 수산화나트륨을 투입하여 pH를 8.4 이상으로 높이면 생성되는 탄산칼슘 등 고형물의 양을 증가시킬 수 있다.Increasing the pH to above 8.4 by adding sodium hydroxide prior to the degassing process, or before or during the aerobic degassing step can increase the amount of solids, such as calcium carbonate, that are produced.

경도유발물질 제거부(10)를 거친 물은 유기물, 경도유발물질 및 황산이온의 농도가 감소하고, 전기전도도가 낮아져 일반적인 공업용수와 비슷한 수질이 된다.Water passing through the hardness-inducing substance removal unit 10 is reduced in the concentration of organic matter, hardness-inducing substance and sulfate ions, and the electrical conductivity is lowered to become water quality similar to general industrial water.

경도유발물질 제거부(10)를 통과하여 부유물 제거조(90)에 공급되는 처리수에 수산화나트륨과 고분자 응집제 등을 투입하여 경도유발물질 및 부유고형물을 응집시킨 후, 침전 또는 부유시켜 제거한다.Sodium hydroxide and a polymer flocculant are added to the treated water supplied to the float removal tank 90 by passing through the hardness-inducing substance removal unit 10 to agglomerate the hardness-inducing substance and the suspended solids, and then precipitate or remove the suspended solids.

본 실시예는 경도유발물질 제거부(10)에서 경도유발물질이 대량으로 제거되므로 부유물 제거조(90)에서 침전시켜 제거해야 하는 경도유발물질이 10~70%로 감소되어 슬러지 처리비 및 처분비가 절감되는 효과가 나타나게 된다.In this embodiment, since the hardness-induced material is removed in a large amount from the hardness-induced material removal unit 10, the hardness-induced material to be precipitated and removed in the suspended matter removal tank 90 is reduced to 10 to 70%, thereby reducing sludge treatment and disposal costs. The effect will be.

본 실시예는 제1공급관(30) 내부에 제2공급관(50)이 설치되고, 제2공급관(50)의 둘레면 일측에는 측 방향으로 분기되어 제1공급관(30) 외측으로 돌출되는 분기관(54)이 형성되며, 제2공급관(50)의 하단에 대응되도록 혼합부(80)가 구비된다.In this embodiment, the second supply pipe (50) is installed inside the first supply pipe (30), the branched pipe protruding outward from the first supply pipe (30) branched on one side of the peripheral surface of the second supply pipe (50) 54 is formed, the mixing unit 80 is provided to correspond to the lower end of the second supply pipe (50).

따라서 제1공급관(30)을 따라 처리수가 공급될 때에 제2공급관(50)을 통해 수산화나트륨 또는 고분자 응집제를 공급하여 경도유발물질의 제거율을 높일 수 있게 된다.Therefore, when treated water is supplied along the first supply pipe 30, sodium hydroxide or a polymer flocculant may be supplied through the second supply pipe 50 to increase the removal rate of the hardness-induced material.

또한, 제2공급관(50)을 따라 낙하하는 수산화나트륨 또는 고분자 응집제는 혼합부(80)의 작용에 의해 처리수와 함께 혼합되면서 수산화나트륨 또는 고분자 응집제와 처리수가 접촉되는 시간을 증가시키게 되어 경도유발물질의 제거율이 보다 더 향상되도록 한다.In addition, the sodium hydroxide or polymer flocculant falling along the second supply pipe 50 is mixed with the treated water by the action of the mixing unit 80 to increase the time for contacting the sodium hydroxide or polymer flocculant and the treated water increases hardness The removal rate of the material is further improved.

혼합부(80)는, 제2공급관(50)의 제2배출홀부(52)와 대향되고, 간격을 유지하도록 배치되고, 제2공급관(50)을 따라 떨어지는 응집제가 충돌되어 유동되도록 하는 굴곡패널(82)과, 굴곡패널(82)의 단부와 제1공급관(30)의 제1배출홀부(32) 사이에 설치되는 복수 개의 지지대(84)를 포함한다.The mixing unit 80 is disposed to face the second discharge hole 52 of the second supply pipe 50 and to maintain a space therebetween, and the curved panel to allow the coagulant falling along the second supply pipe 50 to collide and flow. And a plurality of supports 84 provided between the end of the bend panel 82 and the first discharge hole 32 of the first supply pipe 30.

굴곡패널(82)은 제2공급관(50)의 외경과 비교하여 지름이 크게 형성되고, 제1공급관(30)의 하단 내경과 비교하여 지름이 작게 형성되며, 복수 개의 지지대(84)에 의해 제1공급관(30) 하단 내측에 배치되도록 설치된다.The bending panel 82 has a larger diameter compared to the outer diameter of the second supply pipe 50, and a smaller diameter than the inner diameter of the lower end of the first supply pipe 30, and is formed by a plurality of supports 84. 1 Supply pipe 30 is installed to be disposed inside the lower end.

또한, 굴곡패널(82)은 하측 방향으로 오목하게 형성되며, 제2공급관(50)의 하단과 간격을 유지하도록 배치되므로 제2공급관(50)을 따라 낙하하는 수산화나트륨 또는 고분자 응집제는 굴곡패널(82)에 충돌되어 측 방향으로 진행 방향이 전환되면서 제2공급관(50)과 굴곡패널(82) 사이의 간격을 통해 제1공급관(30) 내측으로 비산된다.In addition, the curved panel 82 is formed to be concave in the downward direction, and disposed so as to maintain a gap with the lower end of the second supply pipe 50, so that the sodium hydroxide or polymer flocculant falling along the second supply pipe 50 is the curved panel ( It collides with 82 and is shifted in the lateral direction, and is scattered into the first supply pipe 30 through the gap between the second supply pipe 50 and the bend panel 82.

따라서 제1공급관(30)의 내벽과 제2공급관(50)의 외벽 사이의 간격을 따라 낙하하는 처리수와 수산화나트륨 또는 고분자 응집제가 혼합되면서 접촉시간이 증가하게 되어 경도유발물질 제거율이 향상되는 효과가 나타나게 된다.Therefore, the treatment time falling along the gap between the inner wall of the first supply pipe 30 and the outer wall of the second supply pipe 50 is mixed with sodium hydroxide or polymer flocculant and the contact time is increased, thereby improving the hardness-induced material removal rate. Will appear.

배출부(70)는, 담수부(12)의 상단으로부터 하측으로 계단 모양으로 형성되는 다수 개의 단차부(74)와, 단차부(74)의 외측 단부에 형성되고, 단차부(74)의 상측으로 연장되어 형성되는 차단패널(72)을 포함한다.The discharge part 70 is formed in the step part 74 formed in the step form from the upper end of the fresh water part 12 to the lower side, and the outer edge part of the step part 74, and the upper side of the step part 74. It includes a blocking panel 72 is formed to extend.

단차부(74)는 담수부(12)의 개방된 상단으로부터 담수부(12) 외측으로 계단 모양으로 형성되고, 단차부(74)의 외측 단부에는 각각 차단패널(72)이 설치된다.The stepped portion 74 is formed in a step shape from the open upper end of the freshwater portion 12 to the freshwater portion 12 outside, and the blocking panel 72 is provided at each of the outer ends of the stepped portion 74.

따라서 담수부(12)에 공급되는 처리수가 담수부(12) 상단으로 흘러넘치면 계단 모양으로 형성되는 다수 개의 단차부(74)를 따라 담수부(12) 외측으로 흐르게 된다.Accordingly, when the treated water supplied to the freshwater part 12 overflows to the top of the freshwater part 12, the freshwater part 12 flows outward of the freshwater part 12 along a plurality of stepped parts 74 formed in a step shape.

이때, 단차부(74)의 단부에는 차단패널(72)이 설치되므로 각각의 단차부(74)에 공급되는 처리부는 차단패널(72)에 의해 일정 시간 동안 담수된 후에 차단패널(72) 상단을 넘어 흘러넘치게 된다.At this time, since the blocking panel 72 is installed at the end of the stepped part 74, the processing parts supplied to the respective stepped parts 74 are desalted by the blocking panel 72 for a predetermined time, and then the top of the blocking panel 72 is closed. It overflows.

처리수가 단차부(74)에 담수되는 동안에 단차부(74)의 상면에 안착되는 여제(60)에 불용성 결정이 석출된다.Insoluble crystals are precipitated in the filtrate 60 resting on the upper surface of the stepped portion 74 while the treated water is fresh in the stepped portion 74.

차단패널(72)의 상단에는 통과홈부(72c)가 형성되도록 다수 개의 걸림돌기(72a)가 간격을 유지하며 형성되고, 걸림돌기(72a)의 상부에는 담수부(12) 측으로 굴곡되어 이루어지는 굴곡부(72b)가 형성된다.A plurality of locking projections 72a are formed to maintain a gap at an upper end of the blocking panel 72 so as to form a passage groove 72c, and a curved portion formed at the upper portion of the locking protrusion 72a is bent toward the fresh water portion 12. 72b) is formed.

굴곡부(72b)는 담수부(12) 측으로 경사지게 형성되므로 여제(60) 및 불용성 결정이 차단패널(72)을 넘어 단차부(74) 외측으로 배출되는 것을 방지하고, 처리수는 통과홈부(72c) 통해 원활히 배출되도록 한다.Since the bent portion 72b is formed to be inclined toward the fresh water portion 12, the filter 60 and the insoluble crystal are prevented from being discharged to the outside of the step portion 74 beyond the blocking panel 72, and the treated water passes through the pass portion 72c. To be discharged smoothly.

또한, 차단패널(72)의 하단에는 단차부(74)를 개폐하는 도어(72d)가 형성되므로 여제(60)의 교체시기가 도래하면 작업자가 도어(72d)를 개방하고, 세척수를 제1공급관(30)을 통해 공급하면 담수부(12)의 상부로 넘치는 세척수가 단차부(74)를 따라 흐르면서 단차부(74)에 안착된 여제(60) 및 불용성 결정이 도어(72d)의 개방에 의해 형성되는 홀부를 통해 차단패널(72) 외측으로 배출된다.In addition, since the door 72d for opening and closing the step portion 74 is formed at the lower end of the blocking panel 72, when the replacement time of the filter 60 arrives, the operator opens the door 72d and the washing water is supplied to the first supply pipe. When supplied through the 30, the washing water overflowing to the upper portion of the fresh water portion 12 flows along the step portion 74, so that the filter 60 and the insoluble crystal settled on the step portion 74 are opened by the door 72d. It is discharged to the outside of the blocking panel 72 through the hole formed.

따라서 여제(60)의 교체 및 불용성 결정의 배출을 용이하게 행할 수 있게 된다.Therefore, it is possible to easily replace the filter 60 and discharge the insoluble crystal.

도어(72d)의 개폐는 별도의 구동부에 의해 이루어질 수 있으며, 이는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 다른 실시예에 대한 구체적인 도면이나 설명은 생략하기로 한다.
Opening and closing of the door 72d may be made by a separate driving unit, which can be easily changed and implemented by those skilled in the art who have recognized the technical configuration of the present invention, and thus detailed drawings or descriptions of other embodiments will be omitted. .

상기와 같이 구성된 본 발명의 일 실시예에 따른 공공하수 및 공장폐수용 폐수처리장치의 작동을 살펴보면 다음과 같다.Looking at the operation of the wastewater treatment apparatus for public sewage and factory wastewater according to an embodiment of the present invention configured as described above are as follows.

먼저, 제지공정 폐수는 우선, 혐기성 반응조(1)에 유입되어 유기물이 제거되고, 혐기성 반응조(1)에는 유기물을 메탄가스로 전환시키는 메탄 생성균 및 황산이온을 황화수소로 전환시키는 황환원균이 존재한다.First, the papermaking process wastewater is first introduced into the anaerobic reactor 1 to remove organic matter. In the anaerobic reactor 1, methane-producing bacteria converting organic substances to methane gas and sulfur reduction bacteria converting sulfate ions to hydrogen sulfide are present. .

혐기성 반응조(1)는 소화조, 혐기성 접촉조 (anaerobic contact process), 상향류식 혐기성 공정 (UASB: up-flow anaerobic sludge blanket) 및 그 변형인 EGSB (extended bed sludge blanket)와 IC (internal circulation), 담체를 이용하여 미생물을 부착시켜 운전하는 공정 (AF: anaerobic filter), UASB와 AF의 혼합형인 하이브리드 반응조 등의 모든 형태의 혐기성 반응조(1)를 사용할 수 있으며 발생된 바이오가스는 연료로 사용하거나 소각한다.Anaerobic reactors (1) include digesters, anaerobic contact processes, up-flow anaerobic sludge blankets (UASBs), and modified bed sludge blankets (EGSB), internal circulation (ICs), and carriers. All types of anaerobic reactors (1) can be used, including anaerobic filters (AF) and hybrid reactors, a mixture of UASB and AF, and the generated biogas is used as fuel or incinerated. .

혐기성 반응조(1)에서 유출되는 처리수는 경도유발물질 제거부(10)에 유입되어 낙하하면서 수중의 이산화탄소가 대기 중으로 탈기되어 pH가 높아지고, pH가 높아지면 중탄산이온이 탄산이온으로 전환되어 칼슘 등 경도유발물질과 결합하여 불용성 고형물인 탄산칼슘 등의 염이 생성된다.The treated water flowing out of the anaerobic reactor 1 enters the hardness-inducing substance removing unit 10 and falls, degassing carbon dioxide into the atmosphere, and increasing the pH, and when the pH is increased, the bicarbonate ions are converted to carbonate ions and calcium. In combination with the hardness-inducing substance, salts such as calcium carbonate, which are insoluble solids, are formed.

이때, 제2공급관(50)을 따라 공급되는 수산화나트륨 또는 고분자 응집제에 의해 탄산칼슘의 생성이 촉진되므로 경도유발물질의 제거율이 향상되며, 굴곡패널(82)에 충돌되어 비산되는 수산화나트륨 또는 고분자 응집제에 처리수의 혼합되면서 경도유발물질의 제거율이 보다 더 향상되는 효과가 나타나게 된다.At this time, the production of calcium carbonate is promoted by the sodium hydroxide or polymer flocculant supplied along the second supply pipe 50, so that the removal rate of the hardness-induced substance is improved, and the sodium hydroxide or the polymer flocculant collided with the bending panel 82 and scattered. As the treated water is mixed, the removal rate of the hardness-induced substance is further improved.

담수부(12)에서 생성되는 염은 단차부(74)를 통과하면서 플라스틱이나 세라믹 등 여재의 표면이나 탄산칼슘 등의 결정에 결정화되어 제거된다.The salt generated in the fresh water part 12 is crystallized and removed from the surface of the media such as plastic or ceramics or crystals of calcium carbonate while passing through the step portion 74.

일정 기간마다 주기적으로 고형물 형태로 존재하는 탄산칼슘 등의 결정을 제거할 때에는 작업자가 도어(72d)를 개방하고, 제1공급관(30)을 통해 세척수를 공급하면 도어(72d)의 개방에 의해 생성되는 홀부를 통해 세척수가 단차부(74) 하측으로 떨어지면서 탄산칼슘 등의 결정을 제거하게 된다.When the crystals, such as calcium carbonate, which periodically exist in solid form at regular intervals, are removed by the operator, the door 72d is opened, and when the washing water is supplied through the first supply pipe 30, the door 72d is opened. The washing water falls to the lower side of the stepped portion 74 to remove crystals such as calcium carbonate.

결정화되어 제거되지 않은 불용화된 경도유발물질은 부유물 제거조(90)로 유입되어 침전 또는 부상시켜 제거된다.Insolubilized hardness-inducing material that has not been crystallized and removed is introduced into the float removal tank 90 to be removed by sedimentation or flotation.

부유물 제거조(90)에서 분리된 탄산칼슘 등의 고형물은 탈수 등 후속 공정을 거쳐서 폐기되고, 부유물 제거조(90)에서 고형물이 제거된 처리수는 공정수로 재사용된다.Solids such as calcium carbonate separated from the float removal tank 90 are discarded through a subsequent process such as dehydration, and the treated water from which the solids are removed from the float removal tank 90 is reused as process water.

이로써, 제지공장 폐수에 함유된 유기물과 칼슘이온 등 경도유발물질을 경제적으로 제거하여 공정수로 재사용하고, 응집제와 폐수의 접촉시간을 증가시켜 효과적인 반응이 일어날 수 있도록 하는 공공하수 및 공장폐수용 폐수처리장치를 제공할 수 있게 된다.
In this way, wastewater for public sewage and factory wastewater can be economically removed from organic wastes and calcium ions such as calcium ions in paper mill wastewater and reused as process water, and effective reactions can be made by increasing the contact time between flocculant and wastewater. It is possible to provide a processing device.
