Abstract
The purpose of this study was to develop model for estimating biodegrability of organic sludge (sewage and papermill) in various environmental conditions. to assume degradable degree with operating time of SRB reactor. and evaluate duratior of organic sludge as carbon source. Average TCOD was 28.7~63.2mg/L in effluent. organic sludge did not much supply carbon source for experimental period. But in point of durability. it seemed that organic sludge was efficient because it was not consumed by degradation of much organic matter within short period. With increasing
다양한 환경조건에서 충진 유기성슬러지, 즉 하수슬러지와 제지슬러지의 분해측도를 추정하기 위한 모델을 개발하고 SRB 반응조의 운전시간에 따른 분해정도를 추정하여 탄소원으로 사용 가능한 유기성슬러지의 지속시간을 예측하였다. 유출 평균 TCOD는 28.7~63.2mg/L를 나타내어 유기성슬러지는 실험기간 동안에 그다지 많은 양의 탄소원을 공급하지 않았으나 지속성 측면에서 단기간내 다량의 유기물 분해에 의한 소모보다는 효율적인 것으로 평가되었다.
