摘要
随着水资源短缺和水环境污染问题日益严重,利用膜净化技术是提高饮用水安全的有效途径之一。其中,反渗透技术具有无相变、设备简单、占地面积少等优点,在我国饮用水行业中得到广泛应用。文中在"十三五"水专项课题的广泛调研基础上,综述了反渗透技术在海水淡化、苦咸水淡化、应急保障供水以及家用供水饮用水行业中的研究概况,通过案例说明反渗透技术的净化效果,均能达到《生活饮用水卫生标准》(GB 5749-2006)的要求,并从有益离子被截留、反渗透浓水的处理、膜污染控制3方面对反渗透技术提出发展建议。
With the shortage of water resources and the pollution of water environment being more serious,it is an effective way to improve the safe level of drinking water by using membrane purification technology.Reverse osmosis technology has been widely used in drinking water in China for its no phase change,simple equipment and small installation area.On the basis of research supported by program of the 13th Five-Year Plan,it is overviewed the research of reverse osmosis technology in seawater desalting,desalination of brackish water,emergency water supply and household water supply of drinking water industry.It is demonstrated that water quality purified by reverse osmosis technology can achieved The Standards for Drinking Water Supply(GB 5749—2006).The suggestions are put forward from three aspects of trapped beneficial ions,concentrated water treatment and membrane fouling control.
