有色金属尾矿库对周边土壤环境污染特征评价及治理

Evaluation and Treatment of Environmental Pollution Characteristics of Non-ferrous Metal Tailings Ponds

对某有色金属尾矿库基本情况进行了简要介绍,对尾矿库周边土壤进行采样,分析和评价了土壤中包含的重金属类型及其含量。结果发现:砷、铬、汞元素的含量只是略高于本地区背景值,污染程度相对较小;铅、镉元素含量则远远超过本地区背景值,说明这两种元素对土壤的污染程度比较严重。提出土壤环境污染治理措施,对于保护土壤环境具有重要的实践意义。

The basic situation of a non-ferrous metal tailings pond is briefly introduced,the soil around the tailings pond is sampled,and the types and contents of heavy metals contained in the soil are analyzed and evaluated.It was found that the content of arsenic,chromium and mercury elements was only slightly higher than the background value of the region,and the degree of pollution was relatively small;the content of lead and cadmium elements far exceeded the background value of the region,indicating that these two elements polluted the soil more serious.It is of great practical significance to protect the soil environment by proposing measures to control soil environmental pollution.
