Abstract:

Microwave heating demonstrates notable benefits compared to conventional heating methods in aspect of heating modes, activation processes, and energy usage expenses. The research of microwave combined advanced oxidation processes (MCAOPs) in organic-contaminated soil remediation is on the rise, attributed to their gentle condition, controllable reaction, superior efficiency, and broad usability. This review examined MCAOPs' advancements in organic contaminated soil remediation, delved into microwave heating technology's evolution and features, outlined prevalent microwave-based advanced oxidation remediation technologies, investigated how factors like microwave power, temperature, and the water-to-soil ratio affected organic contaminants breakdown, elucidated the effects of soil organic matter, minerals, and moisture on these systems, outlined the reaction mechanism, microwave action mechanism and environmental effects of MCAOPs in soil, and summarized current lab- and pilot-scale microwave reactors and optimization issues, as well as proposing a viable conceptual model for amplifying MCAOPs in organic contaminant soil remediation. Ultimately, the review outlined the domains requiring additional exploration in MCAOPs for treating polluted soil, with the aim of enhancing the theoretical basis of MCAOPs and promoting their widespread use.

Key words: microwave heating, advanced oxidation, soil remediation, organic pollutants, degradation
