Oil refinery wastewater discharge involves massive volumes, complex compositions, and highly toxic pollutants. Effective treatment is crucial for environmental protection and sustainable petroleum industry development. The synergistic application of green chemical technologies has become the key to solving this challenge. By organically integrating biological treatment, physicochemical processes, and nanotechnology, various pollutants can be efficiently removed. The combination of biological flocculants and advanced oxidation technologies enhances the removal rate of refractory organic compounds, while membrane separation combined with adsorption techniques effectively eliminates heavy metals and oil residues. This synergy not only improves efficiency and reduces costs but also minimizes secondary pollution, achieving a win-win situation for both environmental protection and economic benefits. This approach paves new pathways for oil refinery wastewater treatment.
