纳滤膜是一种新型分离膜，其截流分子量介于反渗透膜和超滤膜之间，且对无机盐有一定的截流率。国内外纳滤膜制备方法有L-S相转化法、复合法、荷电化法和无机改性等。纳滤膜研究中存在着膜通量小、膜制作成本较高及抗污染性差等问题，因此选择和制备纳滤膜的材料，优化纳滤技术水处理工艺设计，提高纳滤性能，降低制膜成本，减轻膜污染等已成为当今科学研究的重要课题。

Nanofiltration （NF） membrane is a new membrane with molecular weight cutoff between reverse osmosis membranes and ultra filtration membrane, and it can retain inorganic salts. According to the methods of NF membranes preparation at home and abroad, the research progress in this field on L-S phase reversion, composition, charged method and inorganic modification were mainly reviewed. At present, low membrane flue, high production costs and poor antifouling property were existed, therefore, choosing and preparing NF membrane, optimizing the process design of the water treatment of NF membrane, improving the properties of NF membrane, reducing the production costs of NF membrane and increasing the antifouling property were of great importance in NF membrane research.
