Abstract: Petrochemical wastewater typically exhibits characteristics such as high pollutant loads and complex oil-water multiphase structures. Under typical operating conditions like crude oil desalting and certain refining process effluents, it also demonstrates elevated salinity levels, thereby posing significant environmental hazards.This review systematically analyzes the dynamic regulation mechanisms of microplastics in photocatalytic degradation of pollutants. By integrating the characteristics of petrochemical wastewater, it elucidates radical conversion under high salinity, mass transfer limitations in oily systems, enhanced π-π interactions between aromatic pollutants and microplastics, and the radical quenching effect of natural organic matter. This provides a mechanistic framework for photocatalytic treatment of complex systems.

Key words: microplastics, petroleum and petrochemical wastewater, photocatalytic degradation
