【 摘 要 】

In this experiment, we applied a combined process of adsorption and oxidation for the treatment of candied fruit production wastewater. The influence of the pH value and dosage of the Fenton reagent on the treatment effect were investigated. The impact of regeneration temperature, power, and time on the efficacy of the regeneration of adsorbents were examined by ultrasonic wave. The results revealed that at pH 4, the removal rate of COD was 81.74% at a dosage of FeSO4 7H2O of 7 g/L and 40 mL/L of H2O2. The maximum regeneration rate of the adsorbent 90.73%, reached at a temperature of 35 ° C, ultrasonic power of 200 W, and 10 min.
