摘　　要：污泥中富含磷、氮和钾等农作物需要的营养物质,但碍于污泥中残留的重金属离子而难以使用。文章介绍了污泥中重金属的存在形式及作用机理,综述了几种能有效去除重金属的方法(吸附法、淋滤法和化学法),分析了各种方法的优缺点、影响因素、处理效果、适用范围及处理后土地利用的现状,以期处理后的污泥能够作为农用土地,减轻剩余污泥二次污染危害,提高剩余污泥利用率,降低经济投入,变废为宝。The sludge is rich in phosphorus,nitrogen,potassium and other nutrients needed by crops.However,it is difficult to use directly because of the residual heavy metal ions in the sludge.In this paper,the existing forms and the interaction mechanism of heavy metals in the sludge were introduced.Several effective methods for removing heavy metals(adsorption,leaching and chemical methods)were summarized.The advantages and disadvantages,the influencing factors,the treatment effects,the application scope and the current situation of the land use after treatment were analyzed.This paper aims to provide a reference of the agricultural land use in order to reduce the secondary pollution hazard,improve the utilization rate of the surplus sludge,decrease the economic investment and change the waste to the wealth.
