摘要
AMD复合污染流是金属矿山最主要的污染形式,严重威胁着矿区群众的生命安全和制约矿山的可持续发展。治理AMD复合污染流的根本之策在于消除诱发矿山污染的外部环境因素,根本途径在于重建矿区受损的生态系统,恢复生态系统功能。综合分析了金属矿山废弃地污染成因及影响因素,从治理污染诱因的角度提出了一些系统修复的技术思路和方法;并从工程实践角度集成多种技术措施,形成了以工程措施控制水利、地形因子,物化及生物措施控制土壤因子,人工措施改善植被及小气候因子的系统修复技术体系,以期为同类金属矿山的污染修复提供借鉴。
Acid mine drainage(AMD)compound pollution flow is the main pollution form in metal mines,which seriously threaten the life safety of people and restrict the sustainable development of mines.The strategy of controlling AMD compound pollution flow is to eliminate the external environmental factors inducing pollution,the fundamental way to control pollution is to rebuild the damaged ecosystem and restore the self repair and self purification function of the ecosystem.The causes and influencing factors of metal mine wasteland pollution were analyzed.The technical ideas and methods of system repair were put forward,and the technical measures were integrated to form a systematic remediation technology system with engineering measures to control water conservancy and terrain factors,physicochemical and biological measures to control soil factors,and artificial measures to improve vegetation and microclimate factors,which could provide reference for the pollution remediation of similar metal mines.
