摘　　要：膜生物反应器(MBR)具有高效、出水水质好的特点,在生活污水和工业废水处理中得到了应用,但膜污染是MBR广泛应用的主要障碍。介绍了污泥混合液中胞外聚合物(EPS)对膜污染的影响,详细总结了改善活性污泥混合液性质的途径,包括投加添加剂、优化运行参数和培养好氧颗粒污泥。提出了投加天然高分子混凝剂改善污泥性质的方法。Membrane bioreactors （MBRs） have been employed for municipal and industrial wastewater treatments on account of its efficient and excellent effluent quality, but the membrane fouling is main obstacle for wider application of MBRs. The effect of extracellular polymeric substances （EPS） on membrane fouling was introduced, and the measures of improving the activated sludge characteristics, including the addition of additives, optimiza- tion of operating parameters and cultivation of aerobic granular sludge were summarized. The approach of adding a natural polymer coagulant for improving the sludge characteristics was pointed out.
