摘要
尾矿库因势能高、尾矿量大且组分复杂等特点而成为重点环境监管对象。本文分析了尾矿污染地下水的成因与特征,梳理了管控修复技术,总结了不同技术的特点及适用场景,介绍了典型的技术应用案例,并展望了未来的技术发展方向。指出,“堵、截、隔、治”的组合手段是治理尾矿污染地下水的重要措施,可为尾矿库地下水污染的风险管控和修复提供参考。
Tailings impoundment has become the key environmental regulatory object due to its high potential energy,large scale and complex composition.Causes and characteristics of contaminated groundwater from mine tailings are analyzed firstly.Then,control and remediation technologies are sorted out,and the characteristics and application scenarios of different technologies are summarized.Finally,the typical technical application cases are introduced.The development and application directions are prospected.It is pointed out that the combination of“plugging,intercepting,separating,and treating”is a key measure to control the groundwater pollution caused by tailings,which can provide reference for risk management and remediation of groundwater pollution in tailings impoundments.
