Application Analysis of Chemical Oxidation Remediation Technology of PAH Contaminated Soil
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.
