Abstract

호기성 미생물 유동층 반응기에서 혼합미생물층에 의한 산소 반응속도를 연구하였다. 반응기내에서 산소가 한계침투 성분으로 유지될 때의 산소반응속도를 수식화하여 모델식을 얻었으며 글루코오스를 단일 유기물로 하는 합성폐수와 혼합미생물을 이용한 실험으로 모델식을 검토하였다. 실험에 의하면 반응기 입구의 글루코오스 농도가 산소농도 보다 5.4배 이상 크면 반응기내에서 산소가 한계침투 성분으로 유지되었다.

A study was done on the rate of oxygen consumption by a mixed culture microbial film in an aerobic fluidized bed biofilm reactor. For the description of oxygen consumption rate in the reactor where oxygen was a flux limiting component, a mathematical model was obtained and tested by an experiment performed with mixed culture microbes and a synthetic waste water containing glucose as the only carbon source. The experimental result showed that oxygen remains as a critically penetrating component as far as the inlet glucose concentration is above 5.4 times that of oxygen.
