摘　　要：纳滤是介于反渗透和超滤之间的一种膜分离技术,是国内外研究的热点。目前,纳滤技术在水处理领域已经得到日益广泛的应用。综述了纳滤膜在工业废水、海水淡化、饮用水、地下水和地表水处理中的应用;讨论了纳滤膜的污染问题,对两类较难处理的胶体污染和生物污染提出了相应的解决办法;最后讨论了应用NF膜的经济效益。Nanofiltration is a kind of pressure-driven membrane-separation technique similar to reverse osmosis filtration and uhrafiltration. It has become a hot topic of researches all over the world. At present, nanofiltration technology, which has already got extensive application, is mainly used to water treatment field. The application of nanofihration membrane in treatment of the industrial wastewater, desalination, drinking water, ground water and surface water are summarized. And the pollution problem of nanofihration membrane is discussed. The corresponding solutions to colloidal and biological pollution which are more difficult to deal with have also been proposed. Finally, the economic benefit of nanofihration membrane is discussed.
