摘　　要：膜分离技术由于具有设备简单、操作方便、处理效率高和节能环保的优点,已在水环境处理、工业生产、环境保护等领域得到了广泛应用。然而目前使用的大多数膜材料在分离物质时,膜表面和孔内会有污染物聚集,使得膜通量随着运行时间的延长而下降。因此,为了改善分离膜目前存在的问题,扩大膜分离的应用领域,需要对高分子分离膜材料表面进行改性。主要从物理改性、化学改性和表面生物改性方面介绍了膜材料改性的方法,并对其未来发展方向进行了展望。Membrane separation technology has been widely used in water environment treatment,industrial production,environmental protection and other fields because of its simple equipment,convenient operation,high treatment efficiency,energy saving and environmental protection.However,when most of the membrane materials currently used separate substances,contaminants will accumulate on the membrane surface and in the pores,so that the membrane flux decreases with the extension of the running time.Therefore,in order to improve the current problems of separation membranes and expand the application fields of membrane separation,it is necessary to modify the surface of polymer separation membrane materials.The method of membrane material modification is mainly introduced from the aspects of physical modification,chemical modification and surface biological modification,and its future development direction is prospected.
