摘　　要：生物污染是反渗透技术在海水淡化、污水处理等领域应用面临的重要问题之一.本文首先介绍了抗生物污染反渗透膜的重要性;其次根据抗生物污染作用机理将反渗透膜分为抗生物质吸附型和抑菌型,分别综述了这两类膜的制备方法和研究现状;简要概括了新型抗生物污染反渗透膜材料的研究进展;最后根据国内外的研究现状,对抗生物污染反渗透膜的开发进行了展望.Reverse osmosis membranes,which have a widely use in desalination,ultrapure water production and wastewater treatment,have always faced the severe biofouling problem.The research advances in anti-biofouling reverse osmosis membranes are reviewed based on literatures in recent years.The preparation of anti-adhesion reverse osmosis membranes is firstly introduced,including surface hydrophilicity modification and surface charge modification.The preparation of anti-bacterial reverse osmosis membranes with different kinds of biocide is then described.Advanced anti-biofouling membrane materials are also discussed.Finally prospects of anti-biofouling reverse osmosis membranes are anticipated according to the current research progress.
