污染场地调查与修复研究

Investigation and Restoration of Contaminated Sites

本文以某化工园区的土壤地块污染调查与修复处理项目为例,依托水文地质调查、园区地块污染识别、调查采样方案的设计与实施,确定该污染场地内含有的主要污染物为苯、1,2-二氯乙烷、氯乙烯等挥发性污染物。基于此,相关人员选择了常温降解修复工艺实施现场环境污染的修复与处理,并在修复后及时进行效果检测。结果表明,通过常温降解修复工艺的实施,修复后的苯含量均低于评估标准值;污染物去除率不低于99%,满足修复要求。

Taking the investigation and remediation of soil block pollution in a chemical industry park as an example,relying on the design and implementation of hydrogeological investigation,park block pollution identification and survey sampling scheme,this paper determines that the main pollutants contained in the contaminated site are volatile pollutants such as benzene,1,2-dichloroethane and vinyl chloride.Based on this,the normal temperature degradation remediation process was selected to repair and treat the environmental pollution on site,and the effect was detected in time after the repair.The results show that the benzene content after repair is lower than the evaluation standard value,depending on the implementation of the normal temperature degradation repair process.The pollutant removal rate is not less than 99%,which meets the remediation requirements.
