method for recycling and utilizing excess sludge based on the preparation of high-efficiency energy storage electrode material

The invention relates to a method for recycling and utilizing excess sludge based on the preparation of high-efficiency energy storage electrode material, belonging to the technical field of environmental pollution treatment and solid waste comprehensive utilization. Follow these steps, humic acid is purified from sludge by alkali extraction, The graphene oxide suspension is prepared by Hummers method, dilution and ultrasonic treatment, A humic acid and graphene oxide are mixed into a mixed solution according to a certain proportion and then ultrasonic wave is continued for a period of time, At 90 DEG C for 24h with that participation of hydrazine hydrate, aft the reaction, the mixture is pumped through a 0.45 [mu]m aqueous membrane, aft the pumping, the membrane is collected into a petridish, dried in an oven at 80 DEG C, and ground into powdered humic acid/graphene composite material by mortar grinding. The prepared composite material, conductive agent and binder are mixed into electrode paste according to
