摘　　要：土壤重金属和有机物复合污染治理是工业污染场地中治理修复的难点问题。文章以江苏某纺织厂污染场地治理工程为例,重点介绍了项目概况、治理工艺、治理工程实施过程及治理效果。污染地块污染因子为砷、苯并(a)芘、总石油烃(TPH),采用“异位热脱附+土壤淋洗”联合修复工艺,很好的去除了土壤中的污染物,达到修复目标(砷:20 mg/kg,苯并(a)芘:0.55 mg/kg,总石油烃:826 mg/kg),通过治理实践为类似项目提供借鉴。The treatment of soil heavy metal and organic compound pollution is a difficult problem in the treatment and restoration of industrial polluted sites.Taking the polluted site treatment project of a textile factory in Jiangsu as an example,this paper focuses on the project overview,treatment technology,implementation process and treatment effect.The pollution factors of the contaminated land were arsenic,benzo(a)pyrene,and total petroleum hydrocarbon(TPH).The combined remediation process of"ectopic thermal desorption+soil leaching"was adopted to remove the pollutants in the soil well and achieve the remediation target(arsenic:20 mg/kg,benzo(a)pyrene:0.55 mg/kg,total petroleum hydrocarbon:826 mg/kg)to provide lessons for similar projects through governance practices.
