摘　　要：重金属污染是一个全球性的环境问题,对人类生命构成严重威胁。消除环境中的重金属污染物大多数方法受到高费用、处理时间长、地质问题等限制。金属固定化和微生物方法已被证实在处理土壤中的重金属污染物方面是切实可行的。综述了土壤重金属污染的一般状况,阐述各类修复重金属污染方法的优缺点。指出修复受污染土壤需要考虑包括修复方法、土壤污染程度、场地条件以及在不同修复阶段出现的各种可能性。Heavy metal pollution is still a global environmental problem,which poses a serious threat to human life.Various methods have been explored to eliminate heavy metal pollutants in the environment.However,most methods are limited by high cost,processing time,geological problems,etc.Metal immobilization and microbial methods have been proved to be feasible in the treatment of heavy metal pollutants in soil.This paper summarizes the general situation of soil heavy metal pollution,and expounds the shortcomings and advantages of various remediation methods.Remediation of contaminated soil needs to consider remediation methods,soil pollution degree,site conditions,wide adoption and various possibilities at different remediation stages.
