This study proposed a two-stage oxidation process of combining potassium ferrate and hydrogen peroxide to improve the treatment effect of neomycin sulfate wastewater. The experimental results showed a significant synergistic effect between the two oxidation processes, leading to a higher chemical oxygen demand removal rate, and adjusting the treatment parameters appropriately could maximize the treatment effect.
This study proposed a two-stage oxidation process of combining potassium ferrate and hydrogen peroxide to reduce the amount of potassium ferrate and further improve the treatment effect of neomycin sulfate wastewater. Compared with the K2FeO4 single oxidation process and the H2O2 single oxidation process, the K2FeO4 + H2O2 two-stage oxidation process had a higher chemical oxygen demand (COD) removal rate than the sum of the two single oxidation processes, showing a certain synergy. In addition, H2O2 dosage, system acidity, reaction temperature and reaction time did not affect this conclusion. In the first stage, the optimized processing parameters are the dosage of K2FeO4 7 g/L, pH value 4, reaction time 40 min and temperature 40 degrees C. In the latter stage, the appropriate dosage of H2O2 is 20 mL/L, pH value is 3, the reaction time is 50 min and the reaction temperature is 40 degrees C as same as the first stage, the COD removal rate of neomycin sulfate waste-water is 96.83%, showing a good treatment effect and obvious synergistic effect.
