摘要
本研究以四氯乙烯(PCE)污染场地为例,利用气相抽提(SVE)技术对山东某工业园区四氯乙烯污染修复项目开展中试试验研究,在罗茨风机频率30 Hz运行条件下,对包气带土壤中四氯乙烯污染进行修复处理,根据监测及检测结果表明,气相抽提后,超标土壤中四氯乙烯浓度低于183 mg/kg,符合《土壤环境质量建设用地土壤污染风险管控标准(试行)》(GB 36600-2018)二类用地管制值的要求,对包气带中四氯乙烯的去除效果较好;抽提点周围有效影响半径3.464 m以上,本研究为PCE污染场地的修复提供了可靠的数据与实践案例。
This study conducted a field pilot trial of soil vapor extraction(SVE)technology at a tetrachloroethylene(PCE)-contaminated industrial park site in Shandong Province.Under operational conditions with a Roots blower frequency of 30 Hz,the remediation effectively treated PCE contamination in vadose zone soils.Monitoring and analytical results demonstrated that post-SVE treatment achieved PCE concentrations below 183 mg/kg in previously exceeding soils,complying with Class II land use regulatory limits specified in the"Soil Environmental Quality-Risk Control Standard for Soil Contamination of Development Land(GB 36600-2018)".The technology exhibited favorable PCE removal efficiency in the vadose zone,with an effective radius of influence exceeding 3.464 m.
