上海市虹口区某地块土壤修复技术方案实例

Example of Soil Remediation Technology Programme for a Site in Hongkou District, Shanghai

摘要: 目的：为上海市虹口区某铅、总石油烃污染地块的土壤修复提供技术方案。方法：通过铅、石油烃污染常见修复技术比选并结合地块实际情况，选择合适的修复技术路线：总石油烃污染选择高级氧化技术，铅污染选择化学淋洗技术。结果：项目组通过小试试验，确定了药剂的种类和投加浓度、投加量，并通过监测结果确认选择的修复技术路线可以达到修复目标。结论：根据本地块前期的土壤污染状况初步调查、详细调查和风险评估报告，确定了该地块的污染物种类、污染点位信息、修复目标以及修复范围。本案例可为类似污染地块的修复技术路线提供参考。

Abstract: Objective: To provide technical solutions for soil remediation of a lead and total petroleum hydrocarbon contaminated site in Hongkou District, Shanghai. Methods: By comparing the common remediation technologies for lead and petroleum hydrocarbon pollution and combining them with the actual situation of the site, a suitable remediation technology route was selected: advanced oxidation technology for total petroleum hydrocarbon pollution, and chemical drenching technology for lead pollution. Results: The project team determined the types of chemicals and the concentration and dosage of chemicals through small pilot tests, and confirmed that the selected remediation technology route could achieve the remediation objectives through the monitoring results. Conclusion: Based on the preliminary investigation, detailed investigation and risk assessment report of the soil contamination status in the early stage of this site, the types of pollutants, and information of contaminated sites, remediation objectives and remediation scope of this site were determined. This case can provide a reference for the remediation technology route of similar polluted plots.
