金属尾矿土壤重金属污染及修复技术研究现状

Research Status of Heavy Metal Pollution and Remediation Technology in Metal Tailings Soil

目前,我国尾矿堆积量已达170亿t,其以金属尾矿为主,已对生态环境构成严重危害,亟待治理。本文介绍了现阶段我国金属尾矿堆存及土壤污染的基本情况和危害,总结了不同金属尾矿污染土壤的主要重金属特征污染物种类,系统地介绍了金属尾矿重金属污染土壤修复方法,为金属尾矿重金属污染土壤治理提供直接参考。

At present,the accumulation of tailings in China has reached 17 billion tons,it is mainly composed of metal tailings,which has caused serious harm to the ecological environment and needs to be treated urgently.This paper introduces the basic situation and hazards of metal tailings stockpiling and soil pollution in China at this stage,and summarizes the main types of heavy metal characteristic pollutants in the soil polluted by different metal tailings,and systematically introduces the remediation method of heavy metal contaminated soil from metal tailings,so as to provide a direct reference for the treatment of heavy metal contaminated soil from metal tailings.
