Abstract

본 발명은 수질오염 원으로서 큰 부분을 차지하는 유기성 오 · 폐수를 산화구법에 처리하여 방류수 수질기준에 적합한 처리수가 되도록 처리함에 있어 질소 및 인 화합물을 제거하는 방법에 관한 것으로 유입되는 유기성 오 ·폐수중의 고형 협잡물을 제거하고 균등화를 기하는 전처리 공정과, 산화구에서 생물학적 반응으로 질산회반응과 탈질, 타린반응의 각 공정을 동시에 수행하는 오 · 폐수를 침전조로 유입 일정시간 정지하여 침전분리시킨후 상당수는 소독 방류하고 침전된 슬럿지는 탈수기에서 고액 분리하여 발생된 슬럿지 케이크는 부분적 미생물체제를 투입하여 퇴비화하도록 하여 산화구의 부분적 생물학적 질소 및 인 제거방법으로서 BOD 제거반응과 탈질, 탈인 반응이 단일조에서 달성할 수 있으며, 설비구성이 단순하며 운전관리비가 저렴한 것이다.The present invention relates to a method for removing nitrogen and phosphorus compounds in treating organic wastewater, which occupies a large part as a water pollution source, by treating with oxidative sphere to be treated water that meets the effluent water quality standards. Pretreatment process to remove and homogenize solid contaminants, and sewage and sewage from the oxidizing sphere to the sedimentation tank after stopping the sewage / wastewater, which simultaneously perform nitrate, denitrification, and tarin reactions as biological reactions, The sludge cake produced by disinfection and sedimented sludge is solid-liquid separated from the dehydrator to compost with a partial microbial system. Partial biological nitrogen and phosphorus removal of oxidized spheres is achieved by BOD removal, denitrification and dephosphorization in a single tank. It is simple and the configuration of equipment is low. One will.
