摘　　要：水资源短缺是目前制约我国社会经济可持续发展的瓶颈之一,再生水回用是解决该问题的有效措施.膜分离技术具有出水水质优良、占地面积小、易于实现自动化等特点,受到各界的高度重视.本文分析了微滤膜、超滤膜、纳滤膜与反渗透膜的特点,综述了它们在再生水处理中的应用研究现状.结果表明:由于运行成本高等原因,膜分离技术在再生水处理工程应用中较少;我国应进一步加大膜制备技术开发研究的投入,开发抗污染、高通量、低成本的分离膜,促进我国再生水事业的发展.The shortage of water resources is one of the bottlenecks restricting the current economic sustainable development of China,but the recycled water reclamation is an effective way to solve the problem.The membrane separation technology with some advantages,such as good water quality discharged,small covering area,easy realization of automation,etc.,is attached great importance by all the fields of society.In the article,we analyzed the characteristics of micro-filtration membrane,ultra-filtration membrane,nano-filtration membrane and reverses osmosis membrane,and reviewed their application situations in the treatment of recycled water.The investigation results show that the membrane separation technology is rarely applied to recycled water treatment because the operating cost is higher than that of the traditional treatment technology.China should increase the investment of developmental researches about the membrane preparation technology,and lay emphasis on developing anti-pollution,high-flux and low cost membranes,so as to promote the development of the recycled water cause.
