摘要：

Effect of supercritical water oxidation of sewage slaudge was carried out in a lab-scale reactor. Experiments were implemented to investigate the effect of temperature, H2O2 dose, residence time and concentration of catalyst on oxidation of the municipal sewage sludge. The results showed that supercritical water oxidation is effective for removing organic compounds from municipal sewage sludge. Homogenous catalyst, FeSO4 and CuSO4 addition significantly increased TOC removal. TOC removal reached 95.8% under optimum conditions.
