摘　　要：本修复工程采用抽提—高级氧化耦合工艺对苏南某焦化厂退役地块的受污染地下水进行修复处置,修复目标污染物为苯、萘、石油烃(C_(10)~C_(40)),最大修复深度14 m,修复面积4500 m^(2),修复工程历时120天,实际总地下水抽提和处置量约12800 m^(3),修复后地下水中的修复目标污染物浓度水平均可稳定低于修复目标值。抽提出的受污染地下水经过高级氧化单元处理后尾水各项污染物浓度均满足《污水排入城镇下水道水质标准》(GB/T 31962-2015)中的C级标准,可达标排放至市政污水管网。This restoration project had adopted extraction and advanced oxidation coupling process for treating complex contaminated groundwater in the retirement site of a coking plant in southern Jiangsu.The target pollutants of the restoration was benzene,naphthalene and petroleum hydrocarbon(C_(10)~C_(40)).The maximum restoration depth were about 14 meters,and the restoration area were about 4500 square meters.This restoration project had lasted 120 days,and the actual total groundwater extraction and disposal volume were about 12800 cubic meters.After restoration,the concentration level of the remediation target pollutants in the groundwater could be stable lower than the remediation target value.After being treated by advanced oxidation unit,the concentration of various pollutants in the contaminated groundwater meets the Class C standard in the“Wastewater quality standards for discharge to municipal sewers”(GB/T 31962-2015),and can be discharged into the municipal sewage network.
