Research on Synergistic Effect of Microwave Irradiation-Fenton Oxidation Coupling Coagulation Process to Treat Dye Wastewater

Abstract:

From various aspects, enhancement effect of microwave and synergistic effect of the combined process were investigated systematically to treat dye wastewater using microwave irradiation-Fenton oxidation coupling coagulation process. The results showed when microwave was introduced to enhance Fenton oxidation and coagulation process, the degradation efficiency of refractory organic substances in dye wastewater was significantly promoted, and treatment time and various dosages of flocculant, oxidant and catalyzer were also reduced obviously. The synergistic effect discussion of the combined system also indicated that microwave irradiation brought not only the thermal efficiency but also the non-thermal efficiency, which would accelerate to produce more hydroxyl radicals, and promote the molecular polarization of organic substances. The physical and chemical properties of refractory organic substances in dye wastewater could be changed, which would be helpful for the follow-up Fenton oxidation and coagulation process. These facts fully embodied that there existed synergetic effects in microwave irradiation-Fenton oxidation coupling coagulation process.
