In this paper,catalytic wet oxidation process is mainly used to solve the problem of various types of pesticide sludge,high concentration of pollutants,high toxicity,and high cost of incineration disposal as hazardous solid waste.The removal of chemical oxygen demand(COD)and volatile solids(VS)from pesticide sludge by wet air oxidation under different conditions with copper ion as catalytic active substance was studied.The results showed that the addition of catalysts can significantly improve the removal rate of characteristic pollutants in pesticide sludge by catalytic wet oxidation method.Under the conditions of reaction temperature 260℃,stirring speed of 300 r/min,copper ion addition amount of 0.20 g/L,and reaction time of 60 min,the removal rates of VS and COD of sludge can reach more than 90% and 80% respectively.So the catalytic wet oxidation method can provide relevant reference for the reduction and harmless treatment of pollutants in pesticide disposal.
