【 摘 要 】

The advanced oxidation technology based on the theory of sulfate radicals has been extensively studied. In this paper, the degradation of methyl orange over the transition metal catalysts and the catalytic effect on various metal ion catalysts were investigated. The wastewater degradation experiments were judged by the degradation rate and pH under the optimal conditions. In this study, the methyl orange was used as the simulation of the printing and dyeing wastewater, and the experiment was carried out. The vary concentration of methyl orange and metal ions were carried out.. The results showed that persulfate were activated by the metal salts the cobalt metal ions exhibited the strongest performance. The resulted indicated that the methyl orange degradation of 40 mg/L was the appropriate concentration. from varied from 40 mg/L to 120 mg/L interval 20 mg/L, and the catalytic activity of 2g m/L is the best dose at six metal concentrations of 0.5 mg/L, 1 mg/L, 2 mg/L, 3 mg/L, 4 mg/L and 5 mg/L, which provided a very rational basis for the treatment of the practical wastewater.
