摘　　要：针对某隧道弃渣场含重金属渗漏水污染环境事件,进行水质检测及矿物元素分析,合理选取污水处理工艺,确定运行年限,采取生态防护与污水处理相结合的措施高效解决重金属污染水及污泥处置问题,取得了显著的环境效益,可为铁路渣场治理工程提供借鉴。The resolution of heavy metal pollution caused by leachate in one of tunnel waste-disposal yard was put forward. The reasonable wastewater treatment process and its operating life were determined after mineral element analysis and leaching experiments. Ecological protection combined with wastewater treatment measures could efficiently solve the water pollution problems caused by heavy metal and sludge disposal. The project obtained significant environmental benefits, and could provide guidance for similar projects in railway waste-disposal yard.
