摘　　要：矿产资源选冶过程中产生了大量冶炼废渣,废渣无序堆排破坏了生态环境。为解决历史遗留冶炼废渣环境污染问题,以某硫磺冶炼废渣处置工程为例,根据废渣堆存现状和植被生长情况,将治理范围划分为自然恢复区和人工修复区,提出了“风险管控工程+生态修复工程”相结合的综合治理方案,主要治理措施包括废渣中和处理、截流防渗处理、植被恢复和土地复垦等。方案的落地实施,可使废渣堆置区约2.72 hm^(2)的裸露废渣得到有效治理,项目周边生态环境得到恢复,为类似历史遗留矿业固废综合治理工程提供参考。A large amount of smelting waste residue has been left behind during mineral resource extraction and smelting processes,causing severe ecological damage due to uncontrolled disposal.To address the environmental pollution from historical smelting waste residue sites,this study takes a sulfur smelting waste residue disposal project as an example.Based on the current status of residue storage and vegetation growth,the treatment area was divided into natural restoration zones and artificial restoration zones.A comprehensive management scheme combining"risk control engineering+ecological restoration engineering"was proposed,including residue neutralization treatment,interception and seepage prevention,vegetation restoration,and land reclamation.The implementation of this plan effectively treated approximately 2.72 hm^(2)of exposed residue piles,restoring the ecological environment around the project area and providing a reference for similar historical mining solid waste comprehensive management projects.
