采矿区地下水重金属污染特征及其修复技术

Pollution Characteristics of Heavy Metals in Groundwater in Mining Areas and Their Remediation Techniques

地下水是人类赖以生存的重要资源。矿产资源的过度开发使重金属通过渗透作用或迁移扩散进入含水层,导致地下水重金属污染严重。总结了金属矿山开发对地下水资源和地下水质的影响,阐述了地下水污染特征及其修复技术,以期为我国金属矿山开发区地下水污染治理和地下水环境保护提供参考。

Groundwater is an important resource for human survival.With over-exploitation and utilization of mineral resources,the heavy metals produced enter the aquifer through penetration or migration,resulting in serious pollution of heavy metals in groundwater.This paper systematically summarizes the impact of metal resource mine development on groundwater resources and groundwater quality,and expounds the characteristics of groundwater pollution and the progress of its remediation technology,in order to provide some references for groundwater pollution control and groundwater environmental protection in metal mine development zones in China.
