摘　　要：以上海桃浦某污染地块为例,探讨多相抽提联合原位化学氧化技术对工业地块污染地下水的修复效果。该地块地下水中包含VOCs、SVOC及TPH污染,采用压缩空气作为抽提动力,增加废气抽提管道,定期对修复区域地下水进行监测。结果表明,经过1年的多相抽提及1轮原位化学氧化,地下水中污染物浓度远低于修复目标值,达到修复效果。针对深污染、多类型的污染地下水,在有限修复工期内优化多相抽提法联合原位化学氧化技术,能有效提高修复效果。Take a pollution treatment project in Taopu,Shanghai as an example,the remediation effect of multi-phase extraction combined with in situ chemical oxidation technology in remediations of industrial contaminated groundwater sites was explored.The groundwater of the site contains VOCs,SVOC and TPH pollution.Using compressed air as pumping power.Adding the exhaust gas extraction lines,the groundwater in the remediation area should be monitored regularly.After one year of multi-phase extraction and one round of in situ chemical oxidation,the results indicated that the concentration of pollutants in groundwater was far below the remediation target value,achieving a good remediation effect.For the deep pollution,multiple types of polluted groundwater,optimizing the multi-phase extraction combined with in situ chemical oxidation technology within a limited remediation period could effectively improve the remediation effect.
