摘要
石油作为现代工业的血液,被广泛应用于各行各业.但是,其带来的环境污染问题不容忽视,尤其是泄漏等生产事故诱发的土壤污染.化学氧化法因具有修复效能高、成本低及操作便利等优势,常用于石油烃污染土壤修复.本文重点综述了基于过氧化氢和过硫酸盐的高级氧化技术修复石油烃污染土壤过程中常用的活化剂、强化措施、关键影响因素及其效能;汇总了其他氧化剂在修复石油烃污染土壤方面的效果;分析了不同高级氧化技术应用于石油烃污染土壤修复的优缺点;展望了化学氧化法修复石油烃污染土壤未来的发展方向与挑战.
Petroleum is considered to be the blood of the modern industry,which has been widely used in a wide range of industries.However,the environmental pollution caused by petroleum,especially the soil pollution induced by petroleum leakage accidents could not be ignored.The chemical oxidation method is a suitable and widespread remediation approach to petroleumcontaminated soil since it has the advantages of high remediation efficiency,low cost,and easy operation.This paper mainly provided an up-to-date overview of two common advanced oxidation techniques,hydrogen peroxide and persulfate separately.This part focused on the activators,intensification measures,key influencing factors,and their effectiveness.Besides,the effects of other oxidants on the remediation of petroleum hydrocarbon contaminated soil were summarized.Meanwhile,the advantages and disadvantages of various advanced oxidation techniques for the remediation of petroleum hydrocarbon contaminated soil were also highlighted.Finally,the future development directions and challenges of the chemical oxidation method of remediation for petroleum hydrocarbon contaminated soil were also proposed.
