摘　　要：由于污泥中的重金属含量比较高,且大多数未进行无害化处理,只能进行露天堆放,极易造成二次污染,因此污泥中的重金属已成为限制污泥资源化应用的主要因素。文章通过介绍污泥中重金属的污染现状和重金属存在形态的划分,在此基础上对目前常用的四种污泥中重金属的处理方法(化学法、生物淋滤法、动电处理法和植物修复法)进行了综述,并比较了不同方法之间的优点与不足,并提出了新的展望。The heavy metal content in sludge is relatively high and most were not treated and are still harmful. Secondary pol- lution will be easily caused in open dumps of the sludge. Heavy metals in sludge had become a major factor limiting the applica- tion of sludge resources. In this paper, the pollution status and speciation of heavy metals in sludge are introduced. On this basis, four treatment methods （chemistry, bioleaching, electrokinetic method, phytoremediation） of heavy metals in sludge are re- viewed, and their advantages and disadvantages are compared. The prospects in this respect are proposed as well.
