摘　　要：针对某有色金属矿山周边酸性矿山废水存在环境污染隐患问题,进行了除铁、硫化收铜、中和处理试验研究。结果表明:该酸性矿山废水采用混合除铁收铜—中和处理后,污染物达到GB 8979—1996《污水综合排放标准》一级标准要求,产生的中和渣浸出毒性能够满足一般工业固体废物要求,铜渣铜品位可达到35%以上,铜综合回收率可达93.9%。In response to the environmental pollution risks posed by acid mine drainage surrounding a non-ferrous metal mine,experimental study was conducted on the removal of iron,copper recovery by sulfurization and neutralization treatment.The results indicate that after the process of mixed iron removal and copper recovery-neutralization treatment,the pollutants in the acid mine drainage met the requirements of Grade I of the GB 8979-1996"Comprehensive Wastewater Discharge Standard".The produced neutralization residue exhibit leach toxicity levels that meet the general industrial solid waste requirements.The copper grade in the copper residue can reach over 35%,and the comprehensive copper recovery rate can reach 93.9%.

关 键 词：酸性矿山废水 综合治理 铜 铁 回收率
