摘要
多环芳烃是一种强疏水性有机污染物。土壤是多环芳烃积累富集的主要场所。多环芳烃污染会对生态环境与人体健康造成严重影响。针对多环芳烃污染土壤的修复问题,本文介绍了溶剂萃取、化学氧化、热处理、生物修复和联合修复技术的研究进展,总结了每种修复技术自身的特点、优势和局限性。指出,绿色可持续的生物修复技术以及多种土壤修复技术的整合是该领域未来的研究方向。
Polycyclic aromatic hydrocarbons(PAHs)are highly hydrophobic organic pollutants.Soil is the main place where PAHs accumulate and enrich.PAHs pollution will seriously affect the ecological environment and human health.Aiming at the remediation of polycyclic aromatic hydrocarbons contaminated soil,in this paper,the research progress of solvent extraction,chemical oxidation,heat treatment,bioremediation and combined remediation technologies are introduced,and the characteristics,advantages and limitations of each remediation technology are summarized.It is pointed out that the green and sustainable bioremediation technology and the integration of various soil remediation technologies are the directions for future research in this field.
