摘　　要：废水重金属污染是较为严重的环境问题,由于废水重金属具有稳定性好、溶解度高以及可迁移性等特点,故它对环境以及人体都会产生一定的威胁。为了能够降低废水重金属对环境以及人类身体健康的危害,需要采取一定的方法处理废水中的重金属,使其能够达到排放标准。文章旨在综述处理废水重金属的方法及其研究进展,包括化学沉淀法、离子交换法、吸附法、膜分离法、电化学处理法等。Heavy metal pollution in wastewater is a serious environmental problem.Due to the characteristics of good stability,high solubility and mobility of heavy metals in wastewater,Therefore,it will have a certain threat to the environment and human body.In order to reduce the harm of heavy metals in wastewater to the environment and human health,it is necessary to adopt certain methods to treat the heavy metals in wastewater so that it can meet the emission standards.The purpose of this article is to review the methods of treating heavy metals in wastewater and their research progress,including chemical precipitation,ion exchange,adsorption,membrane separation,electrochemical treatment,etc.
