- The sludge cake layer was reversibly removed through extended aeration without effluent, reduced sludge concentration or prolonged cease time of membrane filtration. 通过停止进出水维持空曝气、降低反应器内污泥浓度或延长膜的停抽时间可以使沉积在膜表面的悬浮污泥脱离膜表面,从而使膜过滤能力得到很好的恢复。
- It was also observed that the increase in sludge concentration resulted in the reduction of CFV along membrane surfaces which would influence the operation of the submerged MBR. 同时污泥浓度的上升会导致膜面错流速度的降低,不利于控制膜污染。

- Tests show that the equivalent sludge concentration and the quantity of nitrobacteria in the aerobic tank were increased when some suspended biomass supports were added in it. 试验表明应用浮动填料可大幅度提高曝气池中的活性污泥浓度并增加硝化菌的固着量,因而使该系统对COD、氨氮和总氮的去除能力均优于普通活性污泥系统。
- This paper reviews the design method of membrane bioreactor, including determining hydraulic retention time and sludge retention time, choosing sludge concentration and analyzing the process economy. 摘要综合论述了膜生物反应器的设计方法,包括确定最佳水力停留时间、污泥停留时间、污泥浓度,经济性分析。
- Because of the characteristics of long SRT and high sludge concentration in MBR compared with traditional active sludge process, the biomonitoring is a main parametric of the study of mechanism. 由于该工艺污泥停留时间长、污泥浓度高等特点,与常规活性污泥工艺差距较大,所以对反应器内的生物相监测是研究其处理机理的重要内容。
- This paper reviews the design method of membrane bioreactor,including determining hydraulic retention time and sludge retention time,choosing sludge concentration and analyzing the process economy. 综合论述了膜生物反应器的设计方法,包括确定最佳水力停留时间、污泥停留时间、污泥浓度,经济性分析。
