摘要
以低压驱动膜的微滤膜(MF)与超滤膜(UF),和高压驱动膜的反渗透膜(RO)与纳滤膜(NF)为主,分析了目前国内外膜技术在饮用水除砷方面的效果、影响因素、浓水处理、膜污染及其清洗等方面的应用研究和进展情况,同时对膜技术优缺点及其在除砷中的应用研究方向与前景做了展望。
Excessive arsenic（As） in drinking water has been threatening the human health,which is also one of the most important issues in the Eleventh Five-Year Plan of China.In this paper,the low pressure driven membranes of microfiltration（MF） and ultrafiltration（UF）,and the high pressure driven membranes of reverse osmosis（RO） and nanofiltration（NF） were chosen to discuss and compare there investigation progress of arsenic removal efficiency,influence factors,concentrated water disposal,membrane fouling,and cleaning methods,etc.,application to drinking water.In addition,the disadvantages advantages and the issues aspects of membranes application to arsenic removal were compared and forecasted.
