摘要
目前,饮用水安全问题已经引起人们的高度重视,针对微污染去除的净水工艺也随之快速发展,其中,高分子膜材料技术作为一门高效、新型的关键分离技术,在水质处理、尤其是直饮水制备等领域中应用日益广泛。文章重点分析了微滤、超滤、纳滤和反渗透等膜分离过程在饮用水微污染处理中的应用现状,研究了相关工艺中出现的膜污染问题及其控制方法。
The safety of tap water has been paid increasing attention in recent years,which accompanied by rapid development of the purification process.As one of critical novel effective techniques,membrane technology using polymer materials has been widely used in the field of water treatment,especially in drinking water production.This paper focuses on the application of microfiltration,ultrafiltration,nanofiltration,and reverse osmosis for treatment of micro-polluted raw water.Membrane fouling and controlling method are also analyzed in detail.
