摘要：多环芳烃(PAHs)作为土壤和地下水中常见的有机污染物,严重威胁了人类健康。近年来,基于过硫酸盐(PS)的原位修复技术由于高效快速且成本适中被广泛用于PAHs污染场地修复。介绍了PS的活化方式及机理,分析了4种PS原位注入技术的优缺点及应用条件,综述了土壤环境对PS氧化技术应用的影响,总结了PS在PAHs污染场地修复的实际工程应用,以及基于PS的联合修复技术的发展现状,并对PS氧化技术在实际场地修复的应用和发展进行了展望,以期为PAHs污染场地原位修复提供理论依据和技术支撑。
As a typical organic contaminant in soil and groundwater,polycyclic aromatic hydrocarbons(PAHs)performed a great harm to human health.In recent years,in-situ remediation technology based on persulfate(PS)has been widely used in PAHs contaminanted site remediation due to its high efficiency and moderate cost.In this study,the activation methods and mechanism of PS were introduced,the advantage and disadvantage of 4 PS in-situ injection techniques and their application were analyzed,the effects of soil environment on the application of PS oxidant technology,the actual engineering application of PS in PAHs contaminated site remediation were included,and the current situation of coupling remediation technology development based on PS were summarized.Finally,the application and development of PS oxidant technology in actual site and groundwater remediation were prospected,in order to provide theoretical basis and technical support in further for PAHs contaminated site in-situ remediation.
