Practice of Pollution Site Treatment in a Textile Factory in Jiangsu Province
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.
