In order to broaden the processing conditions of the Fenton method, under the premise of adding a catalyst, the operating conditions of the Fenton-like system were studied. When studying Fe3O4-MnO2-PAC composite material as a catalyst,this experiment find the influence of different single factors on the Fenton-like system. Research shows that when the pH is 2-5, the dosage of Fe3O4-MnO2-PAC is 800mg/L, the dosage of H2O2 is 0.8mol/L, the reaction temperature is 10°C-50°C, Fe3O4-MnO2-PAC catalyst. When used less than five times, it has a better degradation effect on methylene blue wastewater.
