摘　　要：出于对拉萨河水体保护要求,对西藏某铜铅锌矿选矿废水进行处理并全部回用,实现废水的零排放。排放废水中主要含有重金属离子和部分有机污染物,采用"混凝沉淀—ClO2氧化—曝气—吸附—调pH值—回用"处理工艺,可有效去除废水中的重金属离子及有机污染物,满足废水回用生产的要求,实现废水的零排放目标。Flotation wastewater in a Cu-Pb-Zn Mine in Tibet was treated and reused to achieve zero release for the Lhasa river water protection requirements.The wastewater mainly contained heavy metal ions and some organic pollutants.The process of ＂coagulation sedimentation-ClO2 oxidation-aeration-adsorption-adjust pH-reuse＂ was used,which could effectively remove the heavy metal ions and organic pollutants in wastewater,meet the production requirements,and achieve zero release.
