摘　　要：多环芳烃(PAHs)是一类具有致癌、致畸和致突变性质的碳氢化合物。随着工业的发展,大量排放的PAHs在干沉降和湿沉降的作用下富集在土壤中,对土壤环境的污染日益严重,因此急需寻求有效的方法对其进行治理。概述了化学修复技术即化学氧化法、光催化氧化法、电化学修复法、声化学修复法和机械化学法对PAHs污染土壤的修复机理与研究进展,讨论了土壤环境因素对PAHs污染土壤化学修复效果的影响,并对其今后的发展进行了展望。Polycyclic aromatic hydrocarbons（PAHs）are a kind of carcinogenic,teratogenic and mutagenic hydrocarbons.With the development of industry,a large number of emissions of polycyclic aromatic hydrocarbons are gathered in the soil through dry deposition and wet deposition,which brings increasing pollution to soil environment.Therefore,it is urgent to seek effective remediation technology for soil treatment.This paper reviews the mechanism of chemical oxidation process,photocatalytic remediation,electrochemical remediation,sonochemistry remediation and mechanochemical remediation,and also discusses the influence of soil environment factors on chemical remediation.Moreover,the paper prospects the development of chemical remediation technology in the future.
