摘　　要：综述了土壤重金属污染来源、修复重金属污染土壤的主要方法及主要方式,并着重论述了常见的无机固化剂、有机固化剂、离子拮抗剂、复合固化剂的修复机理及修复效果。综合来看向土壤施加固化剂可以有效地吸附和固定土壤重金属,但也存在一定风险,使用不当易造成二次污染。研究发现多种固化剂联合修复较单一固化剂修复效果要更好。在使用土壤固化剂时需结合土壤类型、土壤污染物类型及污染物性质等多方面的因素来综合使用,从而达到修复重金属污染土壤最好的效果。This article reviews sources of soil heavy metal pollution,main methods and methods of remediation of soil contaminated by heavy metals.And the mechanism and effect of inorganic hardener,organic hardener ion antagonist compound hardener are discussed.In general,the application of curing agent to soil can effectively adsorb and fix heavy metals in soil,but there are also some risks.Improper use may easily lead to secondary pollution.It is found that the effect of combined curing agent is better than that of single curing agent.Soil curing agent should be combined with soil type,soil pollutant type and pollutant property,so as to achieve the best effect of remediation of heavy metal contaminated soil.
