Abstract
A kind of compound catalyst containing the main activated component CuO,the second activated component Co3O4 and electronic promoter CeO2 was prepared.The results on treatment of high concentration SDBS wastewater by catalytic wet air oxidation(CWAO) show that the co-catalyst has high activity.The process conditions such as temperature,oxygen partial pressure and pH value of wastewater were measured experimentally and the results show that the removal rate of COD can reach 88.1% with CWAO while only 30.7% without catalyst at the same reaction conditions as follows: temperature 280℃,oxygen partial pressure 3.0MPa,pH value of wastewater 8.2,the initial COD concentration 4?942.1?mg/L and reaction time 120 min.
