摘要
由含砷饮水引起的地方性砷中毒已成为中国一个重要的公共卫生问题。作者综述了近年来国外采用压力驱动膜技术去除饮用水中砷的试验研究成果,重点介绍了膜技术的除砷效果及其影响因素,指出混凝微滤组合工艺不仅除砷效率好,而且能耗低、产水率高,是最佳的饮用水除砷技术之一,应成为我国近期相关研究的重点方向。
Endemic arsenism caused by ingestion of arsenic-beating drinking water has been an important public health problem in China. The experimental results of arsenic removal from drinking water by press-driven membrane technologies in recent years are introduced in this paper. Arsenic removal efficiencies and its influencing factors are mainly discussed. It is put forward the idea that coagulation/microflltration process should be the hotspot in recent study in China due to its high arsenic removal efficiency, low energy consumption and high water recovery.
