The microfiltration (MF)/ultrafiltration (UF) membrane combined process has been widely applied in the field of water treatment. Combined with conventional water treatment process, such as adsorption, precipitation, flocculation and coprecipitation, MF/UF membrane could achieve the satisfactory results which couldn't be obtained by using conventional water treatment process alone. The MF/UF combined process could remove effectively heavy metals, radioactive materials, fluoride and most of the pollutants in backwashing wastewater or reverse osmosis concentrate. This review focused on the removal of specific pollutants from water with MF/UF membrane combined process. The advantages and the future research needs for the MF/UF membrane combined process are also discussed.%MF/UF分离组合工艺在水处理领域已经得到广泛的应用,当其与吸附、化学沉淀、絮凝、共沉淀等常规水处理工艺组合使用时,可获得常规水处理工艺无法得到的效果.膜组合工艺可有效去除水中的重金属、放射性物质、氟化物,还可去除反冲洗废水及RO浓水中大量浓集的污染物.本文对以MF/UF分离组合工艺为核心的水处理系统对水中特殊污染物的去除进行了概述,并指出了MF/UF与常规水处理工艺组合在水处理应用中的优势、存在的问题和发展方向.
