摘要
多环芳烃(PAHs)是土壤中常见的一类持久性有机污染物,焦电、煤矿和冶炼等重点工业场地多存在PAHs超标的问题。基于过硫酸盐(PS)的原位化学氧化技术能够高效去除难降解污染物,被广泛用于土壤PAHs污染的修复。围绕PS原位化学氧化技术在土壤PAHs降解中的应用,详细介绍了铁基和碳基活化材料的开发利用现状以及环境因素对PS氧化体系的影响机制,综述了PS氧化体系对土壤生态功能的危害和环境风险等方面的研究进展,并对该领域未来的发展方向做出了展望。
Polycyclic aromatic hydrocarbons(PAHs)are a class of persistent organic pollutants commonly found in soil,as significant contamination issues often observed at key industrial sites such as coking plants,coal mining areas,and smelting operations.In situ chemical oxidation based on persulfate(PS)has been widely employed for the remediation of PAHs pollution in soil due to its effectiveness in degrading recalcitrant pollutants.Centering on the application of PS-based in situ chemical oxidation in soil PAHs degradation,this study introduced the current development of iron-based and carbon-based activation materials,and detailed the mechanisms of environmental influences on the PS oxidation system,and then summarized research progress on its hazards to soil ecological function and environmental risks.Finally,the future research priorities in this field were prospected.
