金属尾矿区的重金属检测与资源利用

Heavy Metal Detection and Resource Utilization in Metal Tail Mining Area

我国作为矿产资源大国,矿山开发后的尾矿矿渣内重金属释放影响着自然环境和人类身体健康。由于尾矿内含有有价重金属,矿山的综合利用及对尾矿内重金属的回收利用可实现减量化、无害化和资源化处理成为现在重金属污染处理重点。为了控制金属尾矿中的重金属含量在工艺要求和环保标准的范围内,提高金属尾矿再利用的利用率,本文研究分析了金属尾矿的重金属检测技术,通过对金属尾矿区重金属污染土壤的调查,研究重金属在土壤中的含量,通过利用微生物修复技术、修复促进剂治理技术以及治理无害化技术降低尾矿中的重金属含量,为矿区重金属污染地的生态风险提供了参考数据,为尾矿区生态修复奠定了基础,对于尾矿的综合利用具有非常重要的意义。

China is a country with large mineral resources.The release of heavy metals in tailings and slag after mine development affects the natural environment and human health.Because the tailings contain valuable heavy metals,the comprehensive utilization of mines and the recovery and utilization of heavy metals in tailings can realize the reduction,harmless and resourceful treatment,which has become the focus of heavy metal pollution treatment.In order to control the content of heavy metals in metal tailings within the scope of process requirements and environmental protection standards,and improve the utilization rate of metal tailings recycling,this paper studies and analyzes the heavy metal detection technology of metal tailings,and studies the content of heavy metals in the soil through the investigation of heavy metal contaminated soil in the metal tailings area,through the use of microbial remediation technology remediation accelerator treatment technology and harmless treatment technology reduce the content of heavy metals in tailings,provide reference data for the ecological risk of heavy metal contaminated areas in the mining area,lay a foundation for the ecological restoration of tailings area,and are very important for the comprehensive utilization of tailings.
