Abstract

본 발명은 폐수중의 유기물, 질소, 인을 동시에 처리하는 폐수정화법에 관한 것으로, 상세하게는 저류조 1개와 침전조 1개 그리고 미생물을 이용하는 반응조 3개로 구성되며 3개의 미생물 반응조는 공기의 주입을 주기적으로 조절하는 간헐폭기 형태로 운영하며 일정한 시간간격에 따라 반응조의 운영형태 및 유입수의 주입 방향을 바꾸어 운영하는 방법으로 질소와 인의 처리효율을 크게 향상시키는 것이다. 본 발명의 방법은 도시하수처리장, 축선폐수 공동처리장등 질소와 인을 처리하여야 하는 처리장에 효과적으로 이용될 수 있는 폐수정화법에 관한 것이다.The present invention relates to a wastewater purification method for simultaneously treating organic matter, nitrogen, and phosphorus in wastewater. Specifically, the present invention comprises one storage tank, one settling tank, and three reactors using microorganisms, and three microbial reactors periodically inject air. It operates in the form of controlled intermittent aeration and changes the operation mode of the reactor and the direction of injection of influent according to a certain time interval to greatly improve the treatment efficiency of nitrogen and phosphorus. The method of the present invention relates to a wastewater purification method that can be effectively used in the treatment plant to treat nitrogen and phosphorus, such as municipal sewage treatment plant, axis wastewater joint treatment plant.
