Method for repairing, preventing and treating polluted soil in urban core area
The invention relates to an urban core area polluted soil restoration and prevention method, which relates to the technical field of building construction, and comprises the steps of restoration area closing, multiphase extraction construction, water pollution treatment and soil pollution treatment. Closing of the repair area, specifically, closed treatment space construction and repair area supporting construction are included, the repair area is supported after the repair area is confirmed, meanwhile, a closed pollution treatment space is built, and the surrounding environment is prevented from being polluted in the pollution treatment process; multiphase extraction construction is conducted, specifically, multiphase extraction is conducted firstly to extract NAPL and polluted foundation pit water in a site polluted area by combining multiphase extraction with a foundation pit water extraction treatment and repair technology; water pollution treatment: carrying out purification treatment on the polluted water pumped out from the remediation area; soil pollution treatment, wherein polluted soil is excavated and conveyed to a cement plant to be subjected to cement kiln co-treatment. The method is suitable for restoration and prevention of polluted areas of urban core areas, and the influence on the surrounding environment is reduced as much as possible while the polluted areas are restored.
本申请涉及一种城市核心区域污染土修复和防治方法，涉及建筑施工技术的领域，其包括封闭修复区域、多相抽提施工、水污染处理和土壤污染处理；封闭修复区域：包括密闭处理空间施工和修复区支护施工，确认修复区域后对修复区域进行支护，同时建造密闭的污染处理空间，预防污染处理过程中污染周边环境；多相抽提施工：使用多相抽提结合基坑水抽出处理修复技术，先进行多相抽提把场地污染区域内NAPL及污染基坑水抽出；水污染处理：将修复区域抽出的污染水进行净化处理；土污染处理：将污染土壤清挖后运送至水泥厂进行水泥窑协同处置。本申请适用于城市核心区域的污染区域修复和防治,在修复污染区域的同时尽可能降低了对周边环境的影响。
