점감포기에 의한 바실러스 특성을 이용한 폐수의 유기물질 및 질소, 인 처리에 관한 연구
Removal of organic Carbon, Nitrogen and Phosphorus in Wastewater based on tapered Aeration with Bacillus sp.
초록
본 연구는 하 폐수 중의 유기물뿐만 아니라 질소, 인을 생물학적으로 제거하기 위하여 Bacillus sp. 미생물을 사용하였다. Bacillus sp. 미생물이 생존하기에 알맞지 않은 상황에서는 포자를 형성하고, 증식과 포자화를 반복하면서 우점화되는 특성을 발현시키기 위해 점감포기를 실시하였다. 반응기 용존산소 농도는 포기조 1단;
This study was conducted to investigate an aeration tank with RBC process attached Bacillus sp. known as a suitable microorganism for the removing of organic carbon, nitrogen and phosphorus. An aeration tank was based on tapered aeration because Bacillus sp. was well grown in this like environment conditions. The biofilm process with Bacillus sp. as an advanced treatment process could be a best technology for the prominent removal of organic carbon, nitrogen and phosphorus if the mechanism in the process is verified. The operation conditions of DO in the tapered aeration tank were maintained as
