过硫酸盐氧化修复有机污染土壤的研究现状

CurrentStatus on Remediation of Organics-contaminated Soil by Activated Persulfate

基于过硫酸盐新兴高级氧化技术,分析了活化过硫酸盐氧化作用的机理和活化方法,重点介绍了热活化和过渡金属活化过硫酸盐在有机污染土壤中的研究现状,包括菲、柴油、石油、石油烃、芘、十溴联苯醚、对硝基氯苯等污染土壤的处理效果、制约因素或动力学规律等。并结合目前存在的问题提出了5方面的针对性建议:加强基础理论研究,加强污染风险防控;深入研究过硫酸盐活化方式,提高过硫酸盐活化效率和利用率;研发组合修复工艺技术和智能化土壤修复装备;加强对复合污染物土壤的联合修复;开发水土共生体系一体化修复技术。以期相关成果能为活化过硫酸盐修复有机污染土壤相关技术研究与工程应用提供参考。

Research including advanced oxidation technology of persulfate, the oxidation mechanism and activation methods of activated persulfate were analyzed, the research situation of remediation of organics-contaminated soil by thermally activated persulfate and transition metal activated persulfate, on phenanthrene, diesel, crude oil, hydrocarbon, pyrene,deca-brominated diphenyl ether, and p-nitrochlorobenzene,were introduced.Recommendations were made in five aspects:strengthen basic theoreticresearch, increase activate efficiency and utilization ratio of persulfate oxidation, develop synergetic remediation technology and intelligent soil remediation equipment, enhance integrated remediation for soil with combined pollution, and develop water-soil symbiotic remediation technology.Such improvements and developments could be referredto in the engineering application of remediation technologies in the future.
