摘　　要：膜生物反应器是膜分离技术和污水生物处理技术有机结合的一种污水处理工艺,与传统污水处理工艺相比具有很多优点,但膜污染限制了该工艺的广泛应用。介绍了膜污染的定义,系统论述了膜污染的研究进展,着重从改良膜的性质、改善污泥混合液的特性和优化膜分离操作条件等三个方面介绍了国内外有效延缓膜污染的技术措施。Membrane bioreactor （MBR） is a kind of wastewater treatment process in which mem- brane separation technology is coupled with the biological wastewater treatment technology. It has many advantages compared with the conventional wastewater treatment processes. However, membrane fouling restricts the widespread application of the process. The definition of membrane fouling was presented, the progress in membrane fouling research were thoroughly reviewed, and the technical measures for lessening membrane fouling effectively were introduced from three aspects of ameliorating the membrane quality, improving the properties of mixed liquor and optimizing the operational conditions of membrane separation.
