Description:
Under the condition of 35 °C, honeycomb cinder was used as the carrier, nickel as the active ingredient, impregnated for 2h, and calcined at 300 °C for 2h. The catalyst was used to Catalytic Wet Peroxide Oxidation of methylene blue simulated printing and dyeing wastewater. The effect of the amount of catalyst, the amount of catalyst, the reaction temperature and the reaction time on the treatment efficiency and the effect of the self-made catalyst on the simulated wastewater with different concentration gradient were studied in the experiment. The results showed that when the reaction conditions were H 2 O 2 8ml/L, catalyst 12g/L and reaction time 1h, the degradation rate of methylene blue reached more than 77% for the wastewater with concentration ranging from 40 mg/L to 200 mg/L. In addition, at a temperature of 30 DEG C, the wastewater, the concentration was 80mg/L, degradation rate was up to 85.70%.
