摘　　要：简单介绍国外膜材料、膜工艺进展；评述国外有关膜技术在水处理中应用的进展情况，包括饮用水生产、超纯水制备、沙滤池反冲水回用及工业水软化．当前膜组合工艺备受重视，因其将 Ｍ Ｆ、 Ｕ Ｆ 去除颗粒物和螺旋卷绕式组件不易污损的优点同 Ｎ Ｆ、 Ｒ Ｏ 去除 Ｄ Ｂ Ｐ 前体、病毒、合成有机化合物的优点结合起来，并把膜技术与活性炭过滤、臭氧氧化、生物处理等高级水处理技术相结合。Recent developments of membrane materials and membrane technologies were briefly introduced in the paper. The new developments of applications of membrane technologies to water treatment abroad were discussed, which included drinking water and ultrapure water production, reuse of wastewater from sand filter backwash process and softening of industrial water. The integrated membrane processes were valued high recently because they could combine the advantages of MF and UF for removal of particles and minimization of fouling of spiral-wound modules with the benefits of NF and RO for control of DBP precursors, viruses and synthetic organic compounds, and could combine membrane techniques with such advanced treatment processes as activated carbon treatment, ozonation and biological treatment, so they were discussed and stressed here.
