重金属废水处理技术和资源化概述

Review on wastewater treatment of heavy metals and reutilization technique

为了减少重金属废水对环境造成的污染,近些年国内外出现了许多处理重金属废水技术,如化学沉淀法、电解法、吸附法、离子交换法、膜分离法、生物法等,以及这些方法的改进。随着淡水和重金属资源的日益匮乏,在治理污染的同时,实现重金属的回收和水的再利用已备受关注。最后对重金属废水处理技术的发展进行了展望。

In order to reduce the pollution caused by heavy mental waste water,various methods are extensively investigated,such as chemical precipitation,electrolysis,adsorption,ion-exchange,membrane fihration,biological technology and the improved technologies of them.In recent years,as the shortage of freshwater and resources of heavy metals,more attention is paid on the recycling of heavy mental and the reutilization of water by treating the heavy mental containing effluent.Finally,the development of heavy metal wastewater treatment technology is prospected.
