위와 같이 구성되는 본 발명은 스크린조 10에서 오.폐수 및 하수와 함께 유입되는 입자가 큰 부유물질을 제거시킨 후 오.폐수를 무산소조 30으로 이송하게 되는데 이때 스크린조 10에서 유출되는 오.폐수의 양을 조절하기 위하여 유량조정조 20에서 드럼스크린 21에 의해 오.폐수중의 미세 부유물질을 제거한 후 조정펌프 25에 의해 오.폐수 및 하수를 무산소조 30으로 이송시키게 된다.The present invention configured as described above is to remove the large suspended solids particles introduced with the waste water and sewage in the screen tank 10, and then transfer the waste water to the anaerobic tank 30, wherein the waste water flowing out of the screen tank 10 In order to control the volume, the fine-floating material in the wastewater is removed by the drum screen 21 in the flow adjusting tank 20, and the wastewater and sewage are transferred to the anoxic tank 30 by the adjusting pump 25.

상기 무산소조 30에서는 유량조정조 20에서 유입된 처리수를 이용하여 접촉산화조에서 반송된 질산성질소를 탈질시키는 역할을 수행하며, 상기 무산소조 30에서 탈질된 오수는 혐기조 40으로 이송되어 탈인반응이 일어나게 되는데 이때 상기 무산소조와 혐기조내에서 교반장치를 이용하여 오.폐수를 교반시키면 슬러지의 침전을 방지하며 반응속도를 빠르게 할 수 있게 되는 것이다.The anoxic tank 30 serves to denitrify the nitrogenous nitrate returned from the contact oxidation tank by using the treated water introduced from the flow adjusting tank 20, and the denitrified sewage from the anoxic tank 30 is transferred to the anaerobic tank 40 to cause dephosphorization reaction. At this time, by stirring the wastewater using an agitator in the anaerobic tank and anaerobic tank to prevent sludge settling and to speed up the reaction.

이후 혐기조에서 이송되어온 유기물과 암모니아성 질소는 접촉산화조 50 내의 로프형태의 고정상 접촉여재 51에 부착된 미생물과 부유 미생물에 의해 산화되어 정화되어지며, 반송펌프 55에 의해 접촉산화조 30 내의 질산성질소는 무산소조 30으로 반송되어지며, 상기 접촉산화조 50의 일부 처리수는 막분리조 60으로 이송시키며, 상기 접촉산화조 50에서 1차 처리된 처리수는 막분리조 60에서 재처리 및 침지식 분리막 61을 통과시켜 고액분리하여 2차 정화하게 되는데 이때 대장균은 분리막의 공극이 대장균의 크기 보다 작으므로 분리막에 의해 필터링되어지는 것이며, 상기 분리막 61에서 필터링된 처리수는 흡인펌프 65에 의해 처리수조 70으로 이송하고 발생되는 잉여슬러지는 이송펌프 62에 의해 슬러지저류조 80으로 이송한다.Afterwards, organic matter and ammonia nitrogen transferred from the anaerobic tank are oxidized and purified by microorganisms and suspended microorganisms attached to the fixed-phase contact medium 51 in the form of rope in the contact oxidation tank 50, and nitrates in the contact oxidation tank 30 by the return pump 55. Nitrogen is returned to the oxygen-free tank 30, and the treated water of the contact oxidation tank 50 is transferred to the membrane separation tank 60, the treated water first treated in the contact oxidation tank 50 is retreated and immersed in the membrane separation tank 60 After passing through the membrane 61, the solid-liquid separation is performed for secondary purification. In this case, E. coli is filtered by the separation membrane because the pore size of the separation membrane is smaller than that of E. coli, and the treated water filtered in the separation membrane 61 is treated by a suction pump 65. The excess sludge generated at 70 is transferred to the sludge storage tank 80 by the transfer pump 62.

위와 같은 과정에서 블로워 100은 지속적으로 작동하여 상기 유량조정조 20, 접촉산화조 50, 막분리조 60에 공기를 공급하여 유기물 제거 및 질산화에 필요한 산소를 공급하고 슬러지의 침전을 방지하고 슬러지 저류조 80, 슬러지 이송펌프 62에도 공기를 공급하여 슬러지의 부패방지 및 슬러지를 이송하는 역할을 한다.In the above process, the blower 100 continuously operates to supply air to the flow adjusting tank 20, the contact oxidation tank 50, and the membrane separation tank 60 to supply oxygen necessary for organic matter removal and nitrification, to prevent sludge settling, and to maintain the sludge storage tank 80, Air is also supplied to the sludge transfer pump 62 to prevent sludge decay and transfer sludge.

상기한 바와 같이 본 발명에 의한 무산소조, 혐기조 및 고정상 접촉여재와침지식 중공사막을 이용한 오.폐수 및 하수처리 및 처리공법에 의하면, 유기물 및 질소.인 제거를 동시에 효율적으로 제거할 수 있을 뿐 아니라 체류시간을 줄여 반응조의 크기를 크게 줄임으로써 초기 시설비를 크게 줄일 수 있고 또한 약품사용이 없으므로 운전유지 비용을 최소화 할 수 있다.As described above, according to the present invention, the wastewater and sewage treatment and treatment method using an oxygen-free tank, anaerobic tank and fixed bed contact media and immersion hollow fiber membrane can not only remove organic matter and nitrogen and phosphorus simultaneously but also efficiently. By reducing the residence time and greatly reducing the size of the reactor, the initial facility cost can be greatly reduced, and since there is no chemical use, the operation maintenance cost can be minimized.

또한 고농도의 미생물 유지 및 완충작용을 하는 접촉여재의 사용 및 분리막을 이용하여 완벽한 고액분리를 하므로 원수 수질의 급격한 변화에도 항상 안정적인 처리수질을 확보할 수 있다.In addition, it is possible to secure stable water quality at all times even when there is a sudden change in the raw water quality because the perfect solid-liquid separation is achieved by using a contact medium that maintains and buffers a high concentration of microorganisms and uses a membrane.

또한 분리막의 공극이 대장균의 크기 보다 작으므로 방류수질 기준 항목 중의 대장균 사멸을 위한 별도의 소독시설이 필요하지 않게 되는 것이다.In addition, since the pore size of the membrane is smaller than the size of E. coli, a separate disinfection facility for E. coli killing is not required.
