多环芳烃污染土壤化学氧化修复技术的应用分析

Application Analysis of Chemical Oxidation Remediation Technology of PAH Contaminated Soil

多环芳烃(PAHs)是一类常见的环境污染物,其对土壤生态系统和人类健康具有潜在危害。因此,开展土壤中PAHs的化学氧化修复技术研究具有重要的现实意义。本文通过综合分析国内外相关研究成果,总结了目前应用较为广泛的几种土壤化学氧化修复技术,并对其优缺点进行了评述。研究发现,Fenton氧化、高级氧化过程(AOPs)以及二氧化氯等技术在PAHs污染土壤修复方面表现出较好效果。然而,技术应用过程中仍存在一些挑战,如工艺参数的优化、反应产物的处理等。因此,研究人员在今后的研究中需要进一步完善相关技术,提高修复效率并降低成本。

Polycyclic aromatic hydrocarbons(PAHs)are a common class of environmental pollutants that have potential harm to soil ecosystems and human health.Therefore,it is of great practical significance to carry out the chemical oxidation repair technology of PAHs in soil.By analyzing relevant research results at home and abroad,we summarize several popular soil chemical oxidation remediation techniques,and review their advantages and disadvantages.The study found that Fenton oxidation,advanced oxidation processes(AOPs),chlorine dioxide and other technologies showed good results in the remediation of soil contaminated with PAHs.However,there are still some challenges in the technical application process,such as the optimization of process parameters and the processing of reaction products.Therefore,further improvement of related technologies is needed to improve the repair efficiency and reduce the cost in future studies.
