摘　　要：近年来,水过滤的基底材料大多选用纳滤膜(NF),因为相较于反渗透膜(RO)纳滤膜拥有更低的成本、更高的水渗透率。但是,在实际的应用过程中会因为使用环境的不同出现NF渗透率、抗污染率以及寿命下降等问题,选用更长寿命、更强抗污染性以及渗透率滤膜成为近年来一个研究热点。介绍了过滤膜类别,探讨了过滤膜支撑层改性和功能层改性研究情况,提出了其发展方向。In recent years,most of the substrate materials for water filtration are nanofiltration membranes(NF)because they have lower cost and higher water permeability compared to reverse osmosis membranes(RO).However,in the actual application process,NF permeation rate,anti-pollution rate and life span decline may occur due to different use environment,so the choice of membranes with longer life span,stronger anti-pollution line and permeation rate has become a hot research topic in recent years.In this paper,the types of filtration membranes were introduced,the research on the modification of support layer and functional layer of filtration membranes was discussed,and its development direction was put forward.
