| description | The invention relates to the technical field of Fenton sludge treatment, and discloses a Fenton sludge and waste biochar synergistic resourceful treatment method, which comprises: carrying out pyrolysis treatment on Fenton sludge under an anaerobic condition to obtain pyrolyzed Fenton sludge; according to the total iron content in the pyrolyzed Fenton sludge, the sludge larger than the content demarcation point is the first-class pyrolyzed Fenton sludge, and the sludge smaller than the content demarcation point is the second-class pyrolyzed Fenton sludge; the method comprises the following steps: uniformly mixing first-class pyrolysis Fenton sludge and waste biochar to prepare a block mass, uniformly mixing second-class pyrolysis Fenton sludge and waste biochar to obtain a mixed bulk material, and carrying out high-temperature roasting on the block mass or the mixed bulk material at a temperature sufficient to completely decompose organic matters and volatilize other metals into flue gas, but insufficient to |
