摘 要: 介绍了膜分离技术及其特点,对膜分离技术进行了分类,同时阐述了渗透、电渗析、反渗透、超滤、微滤和纳滤这些常规膜分离技术的研究和应用情况,在此基础上介绍了近年来发展起来的液膜、气态膜、双极膜、膜萃取和膜蒸馏这些新型膜分离技术。提出了膜分离技术存在的一些问题、研究方向、展示了膜分离技术的应用前景。 This paper briefly introduces and classifies the membrane separation technology and their characteristics, at the same time it expound the studies and the applications of Dialysis, Electro dialysis, Reverse Osmosis, Ultra filtration, Micro filtration, Nanofiltration which we think they are routine membrane separation technology for wastewater treatment. Based on these this paper introduces the new membrane technology as Liquid membrane, Gas membrane, Bipolar membrane, Membrane Distillation, Liquid membrane extraction. Puts forward the presenting problems, research directions. Prospects the development of separation technology.
