摘要
反渗透膜技术是20世纪60年代兴起的一门新型分离技术,是目前最为先进的分离技术之一,应用广泛。反渗透是渗透的逆过程,它是以压力差为推动力的膜分离过程。简单介绍了反渗透膜技术产生的背景和发展概况,着重论述了国内外反渗透膜技术的研究现状,介绍了反渗透膜在海水和苦咸水淡化、纯水制备以及医药和化工废水处理等方面的应用,并进一步探讨了反渗透膜技术目前存在的问题和未来发展趋势。
Reverse osmosis membrane technology,a new and widely used separation technology arose in 1 960 s,is one of the most advanced separation technologies at present.Reverse osmosis is the inverse process of osmosis and is driven by pressure.In this paper,the background and the development of re-verse osmosis membrane technology are introduced,and its present research is mainly discussed,and its applications in sweater and brackish water desalination,pure water preparation,pharmacy and chemical industry wastewater treatment are described.Finally,the existing problems and future development trends are analyzed.
