饮用水中重金属锑去除技术研究进展

Research Progress of Removal Technology for Heavy Metal Antimony in Drinking Water Treatment

近年来,随着重金属污染事故的多发,原水受重金属锑污染导致的饮用水中锑超标问题逐渐得到关注。文中综述了适用于饮用水中重金属锑去除技术的研究进展,对混凝-沉淀、吸附、膜分离等方法从工艺特点、工艺成本和应用方向上进行了比较,并对除锑技术未来的发展方向进行了展望,为饮用水除锑技术的选择与发展提供一定基础。

In recent years,water pollution of antimony attracts more attention as heavy metal pollution accidents frequently occurring.Research progress of several antimony removal techniques dealing with drinking water (including coagulation-sedimentation,adsorption,membrane separation and so on) are introduced.Comparison between these techniques is also made with discussion of their characteristics,costs and applications.An outlook for the future is presented at the end.It provides a foumdation for the selection and development of antimony removal technology for drinking water.
