摘　　要：膜生物反应器(membrane bioreactor,MBR)作为一种高效的污水处理及回用工艺,近年来备受关注,然而MBR的膜污染问题严重制约了该工艺进一步快速的商业化推广。本文综述了污泥混合液各组分对MBR膜分离的影响,包括溶解性微生物代谢产物(soluble microbial product,SMP)、胞外聚合物(extracellular polymeric substances,EPS)、污泥浓度(mixed liquor suspended solids,MLSS)、颗粒粒径及无机物对膜污染影响,并对该领域未来的研究方向进行了论述。The process of membrane bioreactor（ MBR） has gained considerable attention due to potential advantages over those of conventional biological treatment processes in wastewater treatment and reclamation. However,the membrane fouling has been the major limitation to further development and commercialization of the MBR process. In this paper,the influence of the different components of the mixed liquor on membrane fouling was investigated,which included soluble microbial products（ SMP）,extracellular polymeric substances（ EPS）,mixed liquor suspended solids（ MLSS）,floc size and inorganic substance. Also,the future studies should specifically address the relationship between the mixed liquor characteristics and membrane fouling in real MBR system.
