摘　　要：针对铜矿山酸性水污染治理需求,以江西省永平铜矿为例,系统分析了矿区污水来源、分布特征及现有调节库的处置能力。通过优化调节库布局、改进防渗体系,结合管网优化与分阶段生态修复,构建“设施扩建—管网优化—生态修复”综合治理模式。优化后,该矿新增了5#、6#、7#调节库,总库容提升至2.078×10^(6) m^(3),主要防渗体系都设置2 mm高密度聚乙烯薄膜。结果表明:改造后酸性水收集效率明显提升,外排污染负荷显著降低,形成“地表截流—梯度调蓄—生态修复—渗滤管控”全生命周期治理框架,为高污染风险矿山的环境治理提供了可推广的技术路径。In response to the demand for acidic water pollution treatment in copper mines,taking Jiangxi Yongping Copper Mine as an example,this study systematically analyzed the wastewater sources,distribution characteristics,and treatment capacity of existing regulating reservoir in the mine area.A comprehensive treatment model of"facility expansion-pipeline network optimization-ecological restoration"is constructed by optimizing the layout of the regulating reservoir,improving the anti-seepage system,and combining pipeline network optimization with phased ecological restoration.After optimization,the mine has added 5#,6#,and 7#regulating reservoirs,with a total storage capacity of 2.078×10^(6) m^(3).The main anti-seepage system is equipped with 2 mm high-density polyethylene film.The results show that the collection efficiency of acidic water is significantly improved after the renovation,and the externally-discharged pollutant load is significantly reduced.A full life cycle treatment framework of"surface interception-gradient regulation-ecological restoration-infiltration control"is formed,which provides a scalable technological path for the environmental governance of high pollution risk mines.
