摘　　要：以某铅锌冶炼厂周边土壤为研究对象,综合运用土壤学、环境科学和生态修复技术,探讨了土壤中重金属污染的特征及其治理方法。首先,通过土壤样品采集与实验室分析,确定土壤中主要重金属污染物种类及其含量水平,评估污染程度和空间分布特征。其次,基于污染特征,筛选适宜的物理、化学和生物修复技术,包括土壤固化/稳定化、电动修复、植物修复和微生物修复等,对比分析各种技术的优势与局限性。进一步结合场地条件和污染特征,选择土壤固化/稳定化修复方案。研究结果表明:土壤固化/稳定化修复方案能够有效降低土壤中重金属含量,恢复土壤生态功能,为类似铅锌冶炼厂污染场地的土壤污染治理提供了科学依据和技术支持。Taking the soil around a lead-zinc smelter as the research object,the characteristics and treatment methods of heavy metal pollution in soil were discussed by comprehensive application of soil science,environmental science and ecological restoration technology.First,through soil sample collection and laboratory analysis,the types and content levels of major heavy metal pollutants in the soil were determined,and the pollution degree and spatial distribution characteristics were assessed.Secondly,based on the characteristics of pollution,this study screened suitable physical,chemical and biological remediation technologies,including soil solidification/stabilization,electric remediation,phytoremediation and microbial remediation,and compared and analyzed the advantages and limitations of various technologies.Further,according to the site conditions and pollution characteristics,the soil solidification/stabilization restoration scheme is selected.The results showed that the soil solidification/stabilization restoration scheme could effectively reduce the heavy metal content in soil,restore the soil ecological function,and provide a scientific basis and technical support for soil pollution control of similar lead-zinc smelter contaminated sites.
