连续式FBR处理印染废水的膜污染研究

The Research of Membrane Fouling Process by Continuous FBR

采用尼龙纺织布代替膜生物反应器中的膜组件构建新型尼龙纺织布生物反应器(NWFBR),在连续式运行条件下,对不同活性污泥浓度(MLSS)条件下膜污染过程进行分析。试验结果表明:MLSS对膜污染过程有影响。膜污染过程主要与附着型EPS相关,且EPS中蛋白质浓度对膜污染的影响最大。

The paper reports using the nylon textile cloth instead of the membrane component on the membrane bioreactor to construct a new bioreactor （NWFBR）, under the condition of continuous operation, the membrane fouling process was analyzed under the different conditions of MLSS. The results showed that the MLSS have an impact on membrane fouling process. Membrane fouling process is mainly associated with adherent EPS, and protein content have the greatest influence on membrane fouling.
