Summary:The performance of the catalyst in the multiphase Fenton system is particularly important. It will directly affect the rate of hydroxyl radical generation during the multiphase Fenton reaction which is the main material for oxidative degradation of organic matter in wastewater. Therefore, it is necessary to select a suitable catalyst to construct a multiphase Fenton system. In this study, the preparation of CuO/CeO2 catalyst in multiphase Fenton technology was discussed. The effects of CuO loading, calcination time and calcination temperature on CuO/CeO2 were investigated. The best preparation conditions for the catalytic performance of the catalyst were as follows: the loading of CuO was 7%, the calcination time was 3h and the calcination temperature was 400°C. The catalyst prepared under this condition can achieve a CODCr removal rate of 34% for a plurality of Fenton processes.
