| description | The invention belongs to the technical field of environmental protection, and particularly relates to a modified biomass charcoal catalyst based on activated sludge and a preparation method thereof. The method comprises the following steps: (1) sorting and freeze-drying activated sludge, and pulverizing and sieving the dried activated sludge; (2) impregnating the powdery activated sludge in a modification solution such as FeCl3, CeCl3 and LaCl3, and then filtering and drying the activated sludge to obtain impregnated activated sludge; (3) carrying out anaerobic pyrolysis treatment on the impregnated activated sludge in a nitrogen atmosphere, controlling the heating rate and the constant-temperature pyrolysis time, and cooling the pyrolyzed product to room temperature after pyrolysis is finished, so as to obtain biomass charcoal prepared from the activated sludge; and (4) grinding the biomass charcoal in a ball mill, sieving the biomass charcoal, washing the biomass charcoal with wateruntil the pH value is neu |
