摘　　要：氯代烃类化合物广泛用于塑料、橡胶、染料、润滑油、农药和电子等行业的生产过程,是一种重要的化工原料。在生产使用、存储与处置等环节中,氯代烃类化合物易渗入地下水,对地下水环境造成污染。在某氯代烃污染场地的地下水修复工程中应用高效吹脱技术,以实现污染羽的有效控制。工程实践结果表明:抽出处理后出水中的四氯化碳、1,1,2-三氯乙烷、1,2-二氯乙烷、三氯乙烯和三氯甲烷等污染物浓度均达到《山东省南水北调沿线水污染物综合排放标准》(DB 37/599—2006)和《地下水质量标准》(GB/T 14848—2017)Ⅳ类标准的要求,可为类似挥发性有机物污染场地的地下水修复提供一定技术借鉴和工程示范。Chlorohydrocarbon,which is widely used in the production process of plastics,rubber,dyes,lubricants,pesticides and electronics industries,is an important chemical raw material.In the process of production,storage and disposal,chlorohydrocarbon is easily infiltrated into groundwater and causes pollution to the groundwater environment.High efficiency stripping technology was used in a remediation of chlorohydrocarbon contaminated groundwater project,in order to achieve effective control of pollution plume.The engineering results showed that the concentrations of carbon tetrachloride,1,1,2-trichloroethane,1,2-dichloroethane,trichloroethylene and trichloromethane after treatment met the requirements of Integrated Discharge Standards of Water Pollutants along the South-North Water Diversion Project in Shandong Province(DB 37/599—2006)and ClassⅣof Standard for Groundwater Quality(GB/T 14848—2017).It can provide technical reference and demonstration for groundwater remediation of VOC-contaminated sites.
