Abstract

본 발명은 하폐수의 생물학적 질소제거방법.에 있어서, 외부탄소원을 사용하는 경우 무산소조 전단에 투입되는 외부탄소원으로 인하여 3차 침전지에서의 슬러지 침강성의 악화를 개선하여 질소제거효율을 높이려는 것이다. 본 발명은 2차침전지에서 얻어진 슬러지 또는 포기조의 활성슬러지를 무산소조 또는 3차침전조의 전단으로 첨가하여침전지에서 침강성을 향상시켰다The present invention is to improve the nitrogen removal efficiency by improving the deterioration of sludge sedimentation in the tertiary sedimentation basin due to the external carbon source that is introduced to the anoxic tank front when using the external carbon source. The present invention added the activated sludge of the sludge or aeration tank obtained in the secondary sedimentation cell to the front end of the anoxic tank or the tertiary sedimentation tank to improve the sedimentation characteristics in the sedimentation battery.
