延缓膜生物反应器膜污染的技术措施探讨

膜生物反应器(MBR)是膜分离技术和污水生物处理技术有机结合产生的一种新型污水处理工艺,与传统污水处理工艺相比具有很多优点,但膜污染是限制膜生物反应器广泛应用的关键因素.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3个方面介绍了国内外有效延缓膜污染的技术措施.

Study on the measures to lessen membrane fouling in membrane bioreactor

Membrane bioreactor(MBR) is a kind of process in which membranes coupled with the biological wastewater treatment technology.It provides many advantages compared with the conventional wastewater treatment processes.However,membrane fouling is the most important problem to restrict the widespread application of membrane bioreactor.The paper introduces the definition of membrane fouling,the progress on membrane fouling research are thoroughly reviewed,and it also introduces many measures which can lessen membrane fouling effectively from three aspects: modifying the membrane,changing the properties of the mixed liquor and optimizing the operational conditions of membrane separation.
