Modified fly ash was prepared with acid and alkali as modifier. The influence of modified fly ash as a particle electrode at different reaction conditions on methyl orange dye wastewater decolorizing rate. The results showed that the methyl orange decolorizing rate was up to 96.21%under the conditions of room temperature, 15min reaction time, initial methyl orange concentration for 100 mg/L, modification agent for 10 g/L, current density for 95 mAcm-2, 0.48g NaCl. COD removal rate can reach to 76.8%when electrolyzed 65min under the optimum reaction condition.
