摘要
多环芳烃(PAHs)作为土壤环境中典型的持久性有机污染物,因其高毒性和独特的理化性质,而备受人们关注。近年来,针对PAHs污染土壤修复,过硫酸盐高级氧化工艺作为一种行之有效的策略已展现出巨大的工程应用前景。基于此,本文系统地综述了基于过硫酸盐高级氧化技术在修复PAHs污染土壤的应用研究进展,归纳了活化过硫酸盐的常见方式及机制和活化过硫酸盐修复PAHs污染土壤的影响因素,总结了过硫酸盐高级氧化联合其它修复技术的新思路。最后,提出了活化过硫酸盐高级氧化技术在修复PAHs污染土壤领域面临的挑战及未来发展方向。
Polycyclic aromatic hydrocarbons(PAHs),as a typical persistent organic pollutant in soil environment,have attracted much attention due to their unique physical,chemical properties and high toxicity.In recent decades,activated persulfate advanced oxidation process,as an effective remediation strategy,has shown great engineering application prospects for PAHs-contaminated soil remediation.Based on this,this paper systematically reviewed the application research progress of persulfate-based advanced oxidation technology in remediation of PAHs-contaminated soil,summarized the common ways and mechanisms of activated persulfate and the influencing factors of activated persulfate in remediation of PAHs-contaminated soil,and summarized the new ideas of persulfate-based advanced oxidation combined with other remediation technologies.Finally,the challenges and future development direction of activated persulfate advanced oxidation technology in remediation of PAHs-contaminated soil were proposed.
