Description
본 고안은 침지식 멤브레인 및 황이용 탈질 미생물을 이용한 일체형 오수처리장치에 관한 것으로, 특히 침지식 멤브레인을 이용한 오수 및 하수처리시 탈질 효율을 극대화 하여 질소 제거효율을 높임으로써 처리의 안정성과 설비 및 운전의경제성을 가지는 시스템을 제공하는 것을 특징으로 하는 침지식 멤브레인 및 황이용 탈질 미생물을 이용한 일체형 오수처리장치에 관한 것이다.The present invention relates to an integrated sewage treatment apparatus using immersed membranes and sulfur-using denitrification microorganisms, and in particular, maximization of denitrification efficiency during sewage and sewage treatment using immersed membranes to increase nitrogen removal efficiency, thereby improving the treatment stability and equipment and operation. The present invention relates to an integrated sewage treatment apparatus using an immersion type membrane and sulfur-using denitrifying microorganisms, which provides a system having economical efficiency.
일반적으로 질소 및 인은 생물학적 하폐수처리방법에서 미생물의 활동 및 증식을 위해서 단백질과 핵산합성의 필수 영양소로 작용한다. 그러나 질소 및 인과 같은 영양소가 다량 함유된 경우에 부영향화 현상으로 조류와 같은 자가영양체 미생물이 급속히 번식하여 수질오염을 유발하고 이용가치를 현저히 저하시킨다.In general, nitrogen and phosphorus act as essential nutrients of protein and nucleic acid synthesis for the activity and growth of microorganisms in biological sewage treatment. However, when a large amount of nutrients such as nitrogen and phosphorus are contained, the side effect is to cause autotrophic microorganisms such as algae to multiply rapidly, causing water pollution and significantly reducing the value of use.
이러한 영향으로 최근의 하수처리는 질소 및 인을 제거할 수 있는 생물학적 고도 처리공정이 도입되고 있는 실정이며, A2O공법, 수정Phostrip공법, UCT공법, VIP공법, DNR공법, SBR계열공법 등이 있다.Due to this effect, the recent sewage treatment is a situation in which a highly advanced biological treatment process for removing nitrogen and phosphorus is introduced, and there are A2O method, modified HOSTrip method, UCT method, VIP method, DNR method, and SBR method.
하폐수중의 질소 형태는 유기질소와 암모니아질소로 구성되었으며 이들은 호기성 상태에서 생물학적 산화에 의해 질산성 질소로 바뀌는 질산화 반응과 무산소상태를 유지시키면 질산성 질소를 질소가스로 환원시키는 탈질반응을 통해 제거될 수 있으며 자연상태에서 이러한 물질대사과정에 관여하는 미생물들은 유기물 전환과 암모늄방출이 일어나는 호기상태에서 발견된다.The nitrogen form in the sewage water is composed of organic nitrogen and ammonia nitrogen, which can be removed by nitrification which is converted into nitrate nitrogen by biological oxidation in aerobic state and by denitrification which reduces nitrate nitrogen to nitrogen gas when maintained in anoxic state. In nature, microorganisms involved in these metabolic processes are found in an aerobic state where organic conversion and ammonium release occur.
참고로 질산화 반응과 탈질화 반응 및 탈인 반응을 설명하면 다음과 같다.For reference, the nitrification reaction, the denitrification reaction and the dephosphorization reaction are described as follows.
질산화반응 : 하폐수 중에 함유된 질소는 유기성 질소, 암모니아성 질소(NH3-N), 아질산성질소(NO2-N), 질산성질소 (NO3-N)로 구분되며 유기성질소는 미생물에 의한 가수분해작용으로 암모니아성 질소로 변환되며, 하폐수 중에 존재하는 암모니아성 질소는 Nitrosomonas에의해 아질산성질소로 전화되고 이 질산성질소는Nitrobactor에 의해 질산성질소로 변환되는데 대표적 질산화 공정은 다음과 같다.Nitrification: Nitrogen contained in sewage is divided into organic nitrogen, ammonia nitrogen (NH 3 -N), nitrous nitrogen (NO 2 -N), and nitrogen nitrate (NO 3 -N). It is converted into ammonia nitrogen by hydrolysis, and the ammonia nitrogen present in the sewage is converted into nitrite nitrogen by Nitrosomonas, which is converted to nitrate by Nitrobactor.
NH3 -N + 1.5O2-> NO2 -+ H2O + 2H+(Nitrosomonas) NH 3 - N + 1.5O 2 - > NO 2 - + H 2 O + 2H + (Nitrosomonas)
NO2 -N + 0.5O2-> NO3 -(Nitrobactor) NO 2 - N + 0.5O 2 - > NO 3 - (Nitrobactor)
따라서 전체 반응식은 다음의 식과 같다.Therefore, the overall reaction is as follows.
NH3 -N + 2O2-> NO3 -+ H2O + 2H+ NH 3 - N + 2O 2 - > NO 3 - + H 2 O + 2H +
탈질반응 : 탈질공정은 산소가 존재하지 않는 조건인 무산소상태(Anoxi)에서 산소대신 질산성질소 (NO3-N)와 아질산성질소(NO2-N)등을 전자수용체로 이용하여 NO, N2로 환원시키는 과정이다. 이러한 탈질공정은 미생물이 유기물을 분해할 때 상기 질산염(NO3 -및 아질산염(NO2 -)이 최종 전자수용체로 작용하여 질소가스로 환원되는 이화 질산염 환원반응을 나타내는 것으로 대표적인 탈질경로는 다음과 같다.Denitrification: NOx removal process by using a oxygen-free state (Anoxi) nitrate-nitrogen (NO 3 -N) and Nitrite Nitrogen (NO 2 -N) instead of oxygen in the condition that oxygen does not exist as an electron acceptor NO, N It is a process of reducing to 2 . This denitrification process shows a nitrate reduction reaction in which the nitrates (NO 3 − and nitrite (NO 2 − ) act as final electron acceptors and are reduced to nitrogen gas when microorganisms decompose organic matters. .
NO3 --> NO2 --> NO -> N -> N2 NO 3 - -> NO 2 - -> NO -> N -> N 2
또한, 인은 호기성상태에서 유기인이 인산염상태로 세포내에 축적되고 혐기성상태에서 인산염으로 방출되며 방출된 인산염은 호기성 상태에서 미생물이 다시 과잉으로 섭취하여 체내에 축적하게 된다. 이와 같이 인을 과잉첩취한 미생물을 잉여슬러지로 배출함으로써 하폐수중의 인이 제거된다.In addition, phosphorus is accumulated in the cell in the aerobic state of the organic phosphorus in the phosphate state and released as phosphate in the anaerobic state, the released phosphate is accumulated in the body by excessive intake of microorganisms again in the aerobic state. In this way, by discharging the microorganisms in excess of phosphorus to the excess sludge, phosphorus in the wastewater is removed.
탈인반응 : 혐기상태에서 탈인 미생물들은 저분자 물질을 PHB(poly-β-hydroxybutyric acid)형태로 세포내에 축적하고, 세포내 폴리인산을 가수분해하여 정인산(orthophosphates)을 세포외부로 방출한다. 호기성 상태에서는 세포내 저장된 기질(PHB)을 산화분해과정에서 에너지를 획득하고 다시 이 에너지로 방출된 정인산을 흡수하여 폴리인산으로 세포내에 저장하게 된다. 상기 인의 과잉섭취를 위해서는 우선적으로 인의 방출이 진행되어야 하는데, 인 방출시 산소 외의 다른 전자수용체, 즉 NO3 -와 같은 물질이 존재하면 인 방출이 방해를 받게 되어 효율적인 인 방출을 저해하게 된다. 인의 생물학적 제거란 결국 호기상태에서 인을 과잉섭취한 미생물을 슬러지의 형태로 배출시켜 이루어지는 것으로, 동일한 미생물의 환경변화에 따른 인의 흡수에 의해 제거됨으로 적절한 슬러지 반송이 필요하게 된다.Dephosphorization: In anaerobic conditions, dephosphorous microorganisms accumulate low molecular weight substances in the form of PHB (poly-β-hydroxybutyric acid) and hydrolyze intracellular polyphosphates to release orthophosphates to the outside of cells. In the aerobic state, the intracellular stored substrate (PHB) obtains energy during oxidative decomposition, and absorbs phosphate released by this energy, and stores it in the cell as polyphosphoric acid. The phosphorus overingestion should be proceeded first to proceed with the release of phosphorus, if the presence of other electron acceptors other than oxygen, that is, NO 3 - when phosphorus is released is hindered phosphorus emission is inhibited efficient phosphorus release. Phosphorus biological elimination is achieved by discharging microorganisms in excess of phosphorus in the form of sludge in the form of sludge, and it is necessary to return the sludge properly because it is removed by the absorption of phosphorus due to environmental changes of the same microorganisms.
한편, 일반적인 하폐수 처리공정은 유기물, 질소, 인의 제거를 위해 혐기, 무산소, 호기반응조를 다단으로 설치하며 침전지를 별도로 두어야 하기 때문에 넓은 처리장의 면적과 많은 시설비가 필요했다.On the other hand, the general sewage water treatment process requires an anaerobic, anoxic, and aerobic reactor in multiple stages for the removal of organic matter, nitrogen, and phosphorus, and had to set aside sedimentation basins, thus requiring a large treatment plant area and a large facility cost.

본 고안은 도 1에 도시한 바와 같이 크게 포기조(10)와 탈질 반응조(20)로 이루어지며, 도 2에 도시한 바와 같이 상기 포기조(10)의 내부에는 멤브레인 반응조(11)가 삽입되고, 탈질반응조(20)의 내부에는 여재(21)가 삽입된 형태이다.The present invention is composed of a large aeration tank 10 and a denitrification reaction tank 20 as shown in Figure 1, as shown in Figure 2 the membrane reaction tank 11 is inserted into the interior of the aeration tank 10, denitrification Inside the reactor 20, the filter medium 21 is inserted.
또한, 도 3에 도시한 바와 같이 최초 원수가 유입펌프(31)를 통해 멤브레인 반응조(11)에 유입되고, 탈질반응조(30)에는 상기 멤브레인의 처리수가 흡입펌프(32)를 통해 유입되며, 처리가 완료되면 상수를 외부로 배출시킨다.In addition, as shown in FIG. 3, the first raw water is introduced into the membrane reaction tank 11 through the inflow pump 31, and the treated water of the membrane is introduced into the denitration reaction tank 30 through the suction pump 32. When is completed, discharge the constant to the outside.
상기에서 a는 유입펌프(31)를 통해 원수가 포기조(10)로 이송되는 라인을 표시하고, b는 멤브레인 반응조(11)를 통해 처리된 처리수가 탈질 반응조(20)로 이송되는 라인을 표시하며, c는 처리가 완료된 처리수가 외부로 출력되는 라인을 표시하고 있다.In the above, a denotes a line through which the raw water is transferred to the aeration tank 10 through the inflow pump 31, and b denotes a line through which the treated water treated through the membrane reactor 11 is transferred to the denitrification reactor 20. , c denotes a line to which the number of completed processing is output to the outside.
상기 멤브레인 반응조(11)는 사각형태의 용기로서, 포기조(10) 내에 존재하게 되며, 상기 포기조(10)의 외곽에 사각형태의 탈질반응조(20)가 둘러쌓인 형태이다.The membrane reaction tank 11 is a rectangular container, is present in the aeration tank 10, the rectangular denitrification reaction tank 20 is surrounded on the outer periphery of the aeration tank 10.
따라서, 지름이 작은 사각 형태의 포기조(10) 용기가 지름이 큰 사각 형태의 탈질반응조(20) 용기 내부에 포개져 있는 것처럼 보이게 되며, 이러한 구성을 갖도록 설치하는 이유는 직렬로 나열된 종래의 오수 처리장치에 비해서 좁은 면적에 포기조(10)와 탈질 반응조(20)를 일체로 설치하게 되어 설치면적을 줄일 수 있도록 하기 위함이다.Therefore, it appears that the small diameter square-type aeration tank 10 container is stacked inside the large diameter square denitrification tank 20 container, and the reason for the installation to have such a configuration is the conventional sewage treatment listed in series. The purpose is to reduce the installation area by integrally installing the aeration tank 10 and the denitrification reactor 20 in a smaller area than the apparatus.
상기 포기조(10)는 하부에 산소를 공급하는 산소 발생장치(33)가 설치되고 외부에는 상기 산소 발생장치에 산소를 제공하기 위한 송풍기(34)가 설치되어, 포기조(10) 내부로 이송된 오수에 산소를 공급하게 되며, 상기 멤브레인 반응조(11)에서 산소 공급에 따른 질산화 반응을 일으키게 된다.The aeration tank 10 is provided with an oxygen generator 33 for supplying oxygen to the lower part and a blower 34 for providing oxygen to the oxygen generator is installed outside, the waste water transferred into the aeration tank 10 Oxygen is supplied to the membrane, and the membrane reaction tank 11 causes nitrification according to the oxygen supply.
즉, 멤브레인 반응조(11)에서는 유기물의 제거 및 질산화 반응이 일어나고,상기 멤브레인 반응조(11)를 통과한 오수는 외부 탈질 반응조(20)에서 탈질 반응이 일어나게 된다.That is, the removal of organic matter and nitrification occur in the membrane reaction tank 11, and the wastewater passing through the membrane reaction tank 11 causes the denitrification reaction in the external denitrification reaction tank 20.
특히, 탈질 반응조(20)는 섬모상 여재나 황을 함유한 과립형, 판형 여재 또는 폐플라스틱을 소재로 한 황함유 다공성 여재등의 여재(21)로 충진되어 있고, 황을 이용해서 독립 영양탈질반응을 일으키는 탈질 미생물이 여재(21)에 부착되어 있다.In particular, the denitrification reactor 20 is filled with filtrates 21, such as ciliated media, sulfur-containing granular, plate-shaped media, or sulfur-containing porous media based on waste plastics. A denitrifying microorganism causing a reaction is attached to the filter medium 21.
본 고안의 특징은 멤브레인 유출수를 탈질 반응조(20)에 유입시켰다는 것과, 탈질 반응조(20)에 황 함유 여재(21)와 함께 황 이용 탈질 미생물을 충진한 것이다.A feature of the present invention is that the membrane outflow water was introduced into the denitrification reactor 20, and the denitrification reactor 20 was filled with sulfur-using denitrification microorganisms together with the sulfur-containing media 21.
결국, 질소 제거는 포기조(10)에서 발생하는 질산화 반응 및 탈질 반응조에서 탈질 반응으로 제거되도록 하였다.As a result, the nitrogen removal was to be removed by the denitrification reaction in the nitrification and denitrification reaction tank occurring in the aeration tank (10).
본 고안의 동작을 정리하여 설명하면 다음과 같다.The operation of the present invention is summarized as follows.
본 고안의 장치는 내/외부로 구성된 사각형(또는 원형)의 반응조로서 내부에는 멤브레인 반응조(11)를 설치하고 외부에 탈질 반응조(20)를 설치하여, 내부 멤브레인 반응조(11)에서는 호기에 의한 질산화 반응이 일어나며 멤브레인으로 처리된 유출수는 탈질 반응조(20)로 이송된다.The device of the present invention is a rectangular (or circular) reaction tank composed of an internal / external, and a membrane reactor 11 is installed inside and a denitrification reactor 20 is installed outside, so that the inner membrane reactor 11 is nitrified by exhalation. The reaction occurs and the effluent treated with the membrane is transferred to the denitrification reactor 20.
탈질 반응조(20)로 유입된 멤브레인 유출수는 황을 독립영양으로 이용하는 탈질균에 의해 탈질 반응을 일으키게 되는데, 효율적인 탈질 반응을 위하여 섬모상 여재나 황을 이용하는 과립형, 판형 여재 또는 폐플라스틱을 소재로 한 황 함유 다공성 여재(21)를 사용하여, 여기에 탈질균이 부착 성장하게 된다.Membrane effluent flowing into the denitrification reactor 20 causes denitrification by denitrification bacteria using sulfur as an independent nutrient. For efficient denitrification, the membrane effluent is made of granular, plate-shaped media or waste plastics using ciliated media or sulfur. Using the sulfur-containing porous media 21, denitrification bacteria adhere and grow thereon.
상술한 바와 같이 본 고안은 포기조와 탈질 반응조를 겹쳐지는 형태로 제작하므로 폐수처리장치가 차지하는 공간을 일정 부피내로 줄일 수 있는 효과를 제공한다.As described above, the present invention provides an effect of reducing the space occupied by the wastewater treatment apparatus to a predetermined volume since the aeration tank and the denitrification reaction tank are manufactured in an overlapping form.
비록 본 고안이 상기에서 언급한 바람직한 설명과 관련하여 설명되어졌지만, 본 고안의 요지와 범위로부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능할 것이다. 따라서, 첨부된 청구의 범위는 본 고안의 진정한 범위 내에 속하는 그러한 수정 및 변형은 포함한 것으로 판단할 수 있다.Although the present invention has been described in connection with the above-mentioned preferred description, various other modifications and variations may be made without departing from the spirit and scope of the present invention.
