Zusammenfassung:The invention relates to a decolorization section activated carbon cleaning method, which is characterized by comprising the following steps of: (1) adding recrystallization saccharide, decolorizationmother liquor, deionized water and activated carbon into a decolorization boiling kettle, and controlling the mass ratio of the activated carbon to the recrystallization saccharide to be 1:(150-200)and the mass ratio of the recrystallization saccharide to the (decolorization mother liquor and deionized water) to be (1.0-1.3):1; (2) turning on a decoloration circulating pump and steam, boiling the materials to 85-95DEG C, and feeding filtrate obtained by filtering the materials into a refining section; (3) pumping steam condensate into a circulating tank; (4) pumping the steam condensate in the circulating tank into a coarse filter, returning the cleaned liquid into a circulating tank through a pipeline, and performing circulating for 8-10min; and pumping the steam condensate after cleaning the activated carbon in
