摘要
矿区开采在我国的工业化和城市化进程中发挥了不可或缺的作用,由于过度开采,矿区潜在有毒元素(PTEs)污染的问题逐渐凸显。矿区开采过程中PTEs不仅会对当地的生态环境造成破坏,还会通过降雨、地表径流和大气降尘等方式造成大面积的污染,故开展矿区污染评价和生态治理修复至关重要。本文将围绕矿区PTEs的污染评价方式:内梅罗污染指数、地质累计指数、潜在生态危害指数;矿区生态修复技术:物理修复、化学修复和生物修复技术归纳总结,为今后更好地开展矿区生态修复提供指导。
Mining plays an indispen sable role in the process of industrialization and urbanization in China,and due to over-exploitation,the problem of pollution by potentially toxic elements(PTEs)in mining areas has gradually come to the fore.PTEs in the mining process will not only damage the local ecological environment,but also cause large-scale pollution through rainfall,surface runoff and atmospheric precipitation,etc.Therefore,it is crucial to carry out the evaluation of pollution in the mining area and ecological management and restoration.This paper will summarize the pollution evaluation methods of PTEs in mining areas:Nemero pollution index,geological cumulative index,potential ecological hazard index;and ecological remediation techniques in mining areas:physical remediation,chemical remediation and bioremediation techniques,in order to provide guidance for better ecological remediation in mining areas in the future.
