废弃遗留地重金属污染土壤治理与修复案例研究

A Case Study on Treatment and Remediation of Heavy Metal Contaminated Soil in Abandoned Land

土壤重金属污染主要来自农药、废水、污泥和大气沉降等,重金属污染物在土壤中移动性很小,不易被分解,易随食物链进入人体,潜在危害大。文章选取了废弃遗留地重金属污染土壤治理案例为研究重点,对项目概况、修复工艺选择、方案设计、修复效果评估进行分析,为各地实施重金属污染场地治理与修复提供参考。

Heavy metal pollution in soil mainly comes from pesticides,wastewater,sludge and atmospheric sedimentation.Heavy metal pollutants have little mobility in the soil,are not easy to be decomposed,and are easy to enter the human body with the food chain,which has great potential harm.In this paper,the case of treatment of heavy metal contaminated soil in abandoned land is selected as the research focus,and the general situation of the project,the selection of remediation process,scheme design and remediation effect evaluation are analyzed,in order to provide reference for the treatment and remediation of heavy metal contaminated sites.
