Abstract

폭기조내 용존산소의 농도를 조정하여 질소와 인의 제거효율을 크게 증진시키기 위한 폐수정화법이 개시되어 있다. 반응조내에 담체 및 매체를 투여하여 미생물을 이용하는 2개의 반응조로 구성되고, 2개의 미생물 반응조는 직렬로 연결하여 2단으로 운영하며, 일정한 시간 간격으로 공기의 유입을 조절한다. 또한, 주 반응조 전후에 별도로 혐기성 및 호기성 반응조를 설치하여 질소 및 인의 제거효율을 증진시킨다. 하수처리장이나 축산 폐수 공동처리장과 같이 질소와 인을 처리하는 처리장에서 효과적으로 이용할 수 있다.Disclosed is a wastewater purification method for adjusting the concentration of dissolved oxygen in the aeration tank to greatly increase the removal efficiency of nitrogen and phosphorus. It consists of two reactors using microorganisms by administering a carrier and a medium in the reactor, the two microbial reactors are connected in series to operate in two stages, and regulates the inflow of air at regular time intervals. In addition, anaerobic and aerobic reactors are installed separately before and after the main reactor to enhance nitrogen and phosphorus removal efficiency. It can be effectively used in treatment plants that treat nitrogen and phosphorus, such as sewage treatment plants and livestock wastewater joint treatment plants.
