| description | The invention discloses a preparation and application method of a Ce-Zr/molecular sieve Fenton heterogeneous catalyst, which comprises preparation of the Ce-Zr/molecular sieve Fenton heterogeneous catalyst from active metals such as Ce and Zr and application of the Ce-Zr/molecular sieve Fenton heterogeneous catalyst in high-salt and high-COD wastewater, the active metals such as Ce and Zr are impregnated in a molecular sieve carrier by an ultrasonic impregnation method, and the Ce-Zr/molecular sieve Fenton heterogeneous catalyst is obtained. Preparing a Ce-Zr/molecular sieve Fenton heterogeneous catalyst; the method comprises the following steps: putting a catalyst sample into wastewater with certain salinity and certain COD (Chemical Oxygen Demand), and degrading and removing COD in the high-salinity wastewater by adding an acid solution, a hydrogen peroxide solution and an alkali solution. According to the preparation and application method of the Ce-Zr/molecular sieve Fenton heterogeneous catalyst, adopted |
