摘要
经场地调查和人体健康评估表明,上海市某工业地块土壤受到砷,地下水受到砷、苯并(a)芘和石油烃污染,污染物浓度超过了人体健康风险可接受水平,需要进行修复.土壤修复技术采用原地异位固化或稳定化技术;地下水砷修复采用抽提,化学氧化;苯并(a)芘、总石油烃污染采用多相抽提联合氧化技术.对整个修复过程进行阶段性验收、现场采样监测,监测结果符合评价标准,修复工程效果评估合格.
Abstract
Site investigations and human health risk assessments have indicated that the soil at a certain industrial plot in Shanghai is contaminated with arsenic,and the groundwater is contaminated with arsenic,benzo(a)pyrene,and petroleum hydrocarbons.The concentrations of these pollutants exceed the acceptable levels for human health risk,necessitating remediation.The soil remediation technology employed in-situ solidification or stabilization techniques;arsenic in the groundwater was remediated using extraction and chemical oxidation;benzo(a)pyrene and total petroleum hydrocarbons were remediated using a combination of multi-phase extraction and oxidation technology.The entire remediation process was subject to phased acceptance and on-site sampling monitoring.The monitoring results met the evaluation criteria,and the remediation project was assessed as qualified.
