摘　　要：综述了纳滤膜的特点 ,包括孔径范围处于纳米级 ,膜体带有电性基团 ,操作压力低 ,对二价和高价离子的截留率明显高于单价离子等。介绍了纳滤膜在水处理中的应用 ,包括软化水处理、饮用水净化、地下水中硝酸盐的去除、二级污水的深度处理、工业废水的处理等。The characteristics of nanofilter membrane such as the range of aperture locates nanometer grade,negatively or positively charged,low operate pressure and di and multivalent ions were highly rejected than monovalent ions were summarized in this paper.The applications of nanofiltration in the field of water treatment such as removal of hardness,purification of drinking water,removal of nitrate from wellwater,secondary wastewater treatment and industrial wastewater treatment were also introduced.
