摘　　要：以某铅锌采选矿企业为例,对企业及周边土壤和地下水污染状况进行检测分析。分析结果表明,土壤45项基本项污染物及重金属锌的指标中仅有锌和砷含量超过国标(GB 36600—2018)的筛选值,但低于管控值。地下水水质中镉、pH及总大肠杆菌数指标超过国标(GB 14848—2017)Ⅲ类水质,镉和pH指标都属于Ⅳ类地下水水质,总大肠杆菌数超标严重,研究结果将为铅锌行业场地环境治理提供参考。Taking a lead-zinc mining and beneficiation enterprise as an example,this paper detected and analyzed the pollution status of soil and groundwater around the enterprise.The analysis results showed that among the 45 basic items of soil and the indicator of heavy metal zinc,only the contents of zinc and arsenic exceed the screening value of the national standard(GB 36600—2018),but were lower than the control value of the national standard.The indexes of Cadmium,pH and total Escherichia coli in groundwater quality exceed the standard of class III water quality(GB 14848—2017).Cadmium and pH indicators belonged to class IV groundwater quality,and the total Escherichia coli exceeded the standard seriously.The research results would provide more comprehensive reference for the site environmental treatment of lead-zinc industry.
