Dimethyl phthalate, a common ingredient in the manufacture of plastics, was typical persistent substance organic wastewater environment due to its lipophilic and refractory properties. In order achieve higher degradation dimethyl this study used an experimentally constructed high-pressure resistant microwave-catalyzed experimental system, which could establish coupling between microwave field pressure wet oxidation process. Three different types catalysts were investigated for catalytic degradation. The effects variables such as reaction temperature, system catalyst concentration on removal phthalate also investigated. microwave-induced catalysis increasing temperature effectively increase rate constant. addition, COD content reduced from 4161.8 mg/L 1710.5 within 5 min. energy flow economy indices whole process comprehensively analyzed. Finally, analytical results intermediates other characterization techniques show that pollutant degraded by ·OH.
