纳滤膜技术在废水深度处理中的膜污染及控制研究进展

Fouling and control of nanofiltration membrane in the advanced treatment of wastewater: An overview

纳滤(Nanofiltration)膜技术是实现废水再生利用的有效途径,但膜污染是限制其推广应用的主要因素之一.本文总结了纳滤膜技术在废水深度处理过程中的膜污染研究现状,分析了膜污染分析方法研究进展,并探讨了纳滤膜污染的控制策略,最后对今后的工作重点进行了展望,以期为纳滤膜技术在不同废水深度处理过程中的膜污染调控提供参考.

Nanofiltration（ NF） is considered to be a promising alternative process for the reuse of wastewater recently. However,membrane fouling is one of the major obstacles for the practical application of NF in the treatment of wastewater. The purpose of this paper is to summarize status of NF membrane fouling in the treatment of wastewater,to thoroughly review the analyze methods and control strategies of membrane fouling,and to propose the future research direction.
