某制革企业旧址污染场地修复工程实例

Project Case of Organic Contaminated Site in a Tannery Abandoned Site

介绍了某制革厂旧址污染场地异位化学氧化修复工程。通过前期场地调查及风险评估,确定场地污染现状、修复目标及修复工程量。通过修复技术比选,确定适合本项目的修复技术路线。通过小试试验确定适宜的氧化药剂及药剂添加范围。通过现场中试试验,确定不同污染程度污染土壤的药剂投加量。修复施工完成后,由第三方检测机构对修复工程进行采样、检测,根据检测结果评估修复质量。本修复工程的成功实施能够为制革行业其他类似污染场地土壤修复项目提供参考。

This paper introduced the heterotopic chemical oxidation remedition engineering of organic contaminated site in a tannery abandoned site.The pollution status,the target values of soil remediation and the quantities of the project were determined by using pollution site investigation and risk assessment.The technology roadmap of soil remediation was determined after comparison and selection.The suitable remedition agent and additon ratio for the soil polluted by different pollution levels were determined through lab-scale experiments and pilot tests.A third party testing corporation performed both sampling and analysis to confirmed that the treated groundwater reached target values after the end of engineering.Successful implementation of this project showed that the heavy metal contaminated soil was remediated effectively,which could provide reference for other similar projects.
