摘　　要：介绍了膜生物反应器(MBR)中膜污染形成的机理,分析了膜材质、膜孔大小、膜表面粗糙度、过膜溶质性质、处理液性质、过膜操作方式等因素对膜孔堵塞的影响,阐述了控制膜孔堵塞的重点和主要方法,指出了今后解决膜孔堵塞问题的研究重点。The creation mechanism of membrane fouling in membrane bioreactor （MBR） is introduced. The factors affecting membrane pore blocking are analyzed, such as the material, pore size, the roughness of membrane surface, the properties of solute and treating solution, and the operation mode. The keys and methods to control of membrane pore blocking are presented and the keystones for further research are pointed out.
