摘　　要：纳滤膜被广泛用于水处理、食品加工、生物化学与制药、石油开采及提炼等方面,但膜污染引起的性能下降、能耗增加及膜使用寿命缩短等却极大地增加了纳滤成本。为降低膜污染,人们在开发抗污染纳滤膜方面做了大量研究工作.本文在简要介绍纳滤膜污染的种类、污染机制等的基础上,着重总结了近年来研究者采用表面改性、共混改性、层层自组装等方法制备抗污染高分子纳滤膜方面取得的进展,并就今后的研究方向提出建议.Nanofiltration membrane is widely used in water treatment,food processing,biochemistry and pharmaceutical,oil extraction and refining etc.However,the performance degradation,increased energy consumption and the shortened service life of the membrane caused by membrane fouling have greatly increased the cost of nanofiltration technology.In order to reduce the membrane fouling and develop antifouling nanofiltration membrane,a lot of research work has been carried out.On the basis of elaborating the fouling types and mechanism of nanofiltration membrane,this paper focused on the construction of anti-fouling polymeric nanofiltration membrane as surface modification,blending modification and self-assembling etc.The suggestions on future research were also presented.
