摘要
纳滤是近十几年来才发展起来的一种新型的介于超滤与反渗透之间的膜水处理技术,由于其具有能截留低分子有机物和多价盐,低压操作和离子选择性等优点,在水处理中被越来越多地应用和研究。本文在介绍纳滤膜的分离机理的基础上综述了纳滤膜技术在微污染水处理方面的应用研究进展,并对其处理过程中的影响因素进行了分析,最后指出了它的应用前景。
Nanofiltration(NF) is a kind of new membrane wastewater treatment technology which is between UF membrane and RO membrane. It takes the advantages of retaining low relative molecular mass organism and high-valent salt, low operation pressure, and high selection, so that it has been more and more studied and applied to wastewater treatment. In this paper the seperation mechanism of nanofiltration was introduced, on the basis of which the promotion of NF's research and applications to micro-pollution water treatment was summarized. The effects of some factors in the process of treatment were also analyzed. Finally its development vista was pointed out.
