Determination of operation parameter on intermittently aerated activated sludge system by computer simulation model

컴퓨터 예측모델을 활용한 간헐폭기 활성슬러지 시스템의 운영인자 결정

In this research effect of SRT, feeding pattern and reactor configuration on intermittently aerated activated sludge system was evaluated by using computer simulation model. T- N removal was affected to the SRT. SRT for the effective T- N removal was 156ay or longer. Feeding pattern in intermittently aerated activated sludge system was affect to the T- N removal. Feeding pattern which 100% loading to the first reactor was most effective for T- N removal. When multi- stage of 2- stage or more was operated, COD and T- N in effluent removal was nearly the same.
