摘要
调查了湖南省郴县东西河流域尾矿重金属的污染状况,分析了土壤与水体中重金属的形态分布特征,将污染区分为轻、中、重三个区域并在不同的污染区提出了相应的防治技术。试验结果表明,利用农业生态工程技术来防治多金属复合污染获得了较好的治理效果和经济效益。
In this paper, we investigated the pollution status of tail mine heavy metals in East River and West River valley in Chen County and analyzed the distribution characteristics of heavy metals in the soil and water. The polluted areas were divided into three types, which contained slight, medium and high concentrations of heavy metals, respectively. Comprehensive methods were used for controlling heavy metal contamination in different zones. Finally it has been found that the agro-ecosystem engineering techniques were satisfactory to harnessmulti-metal pollution.
