Abstract

본 발명은 폐수에서 유기물, 질소, 인등과 같은 부영양화 물질을 높은 효율로 제거하기 위한 폐수처리 방법에 관한 것이다. 본 발명에 따라 혐기조에서 유기물을 제거하고 고분자 형태의 인을 정인산 형태로 용출하며, 탈질조에서 질산화물을 질소기체 형태로 제거하고, 폭기조에서 암모니아성 질소를 질산화함과 동시에 정인산 형태의 인을 미생물에 과잉 섭취시키고, 폭기조 유출수를 한외 여과막으로 여과하여 처리수를 방출하고 농축물을 얻은 후 농축물을 침전조에서 침전시켜 상등수는 방류하고 침전슬러지는 탈질조로 반송시킴을 포함하는, 개선된 질소 및 인의 생물학적 제거방법이 제공된다.The present invention relates to a wastewater treatment method for efficiently removing eutrophic substances such as organic matter, nitrogen, phosphorus and the like from wastewater. According to the present invention, the organic matter is removed from the anaerobic tank, the phosphorus in the form of polymer is eluted in the form of phosphorous acid, the nitrogen oxide is removed in the form of nitrogen gas in the denitrification tank, and the phosphorus in the form of phosphorous in the form of phosphorous acid is applied to the microorganism at the same time. Biologically improved nitrogen and phosphorus, including excess intake, filtration of the aeration tank effluent with an ultrafiltration membrane to release the treated water and obtaining a concentrate, followed by precipitation of the concentrate in the settling tank to discharge the supernatant and return the settling sludge to the denitrification tank. A removal method is provided.
