Abstract

본 발명은 계절과 장치의 설치지역에 관계없이 고부하 처리에서 저부하고도 처리까지 항상 높은 효율로 오수의 처리를 할 수 있게 하고, 또한 잉여오니를 장치밖으로 일체 배출하지 않게 하는 활성 오니상에 의한 오수처리장치에 관한 것이다. 상기 오수처리장치의 구성으로서, 다수의 활성오니상(34), (36), (38), (40) 및 폭기관(33)이 배설된 오수처리조(14), (16), (18), (20)내에 선회수류 발생수단(42), (46)과 가온 배관(48)을 설치하고, 제3오수처리(18)에서 제1, 제2처리조(14), (16)에 처리중인 오수를 되돌리며, 침강조(22) 및 오니소화조(26)을 병설하여 오수처리후의 상징수를 제1오수처리조에 송급한다.
