摘　　要：矿山环境修复是建设“美丽中国”和实施“两山”政策的具体措施之一。修复尾矿废渣导致的水体污染问题也是众多矿山环境问题中的重要一环。本文对湘潭锰矿周边进行采样研究,尾矿周边重金属浓度最高是Mn,其次按顺序为Cd、Zn、Pb等;Mn在部分地区污染严重,Cd和Cr污染存在潜在威胁。该研究致力于分析污染物,采用生物炭或改性生物炭进行尾矿区修复。mine environment restoration is one of the specific measures to build a"beautiful China"and implement the"two mountains"policy.Remediation of water pollution caused by tailings is also an important part of many mine environmental problems.In this paper,the sampling study around Xiangtan Manganese Mine shows that the highest concentration of heavy metals around the tailings is Mn,followed by Cd,Zn,Pb,etc;Mn pollution is serious in some areas,and Cd and Cr pollution is a potential threat.This study is devoted to analyzing pollutants and using biochar or modified biochar to repair tailings.
