PROBLEM TO BE SOLVED: To provide a regeneration method for activated carbon for reducing the acid concentration in acid wash, and for shortening the cleaning time, and for simplifying post-washing, and for maintaining the strength of the activated carbon to be obtained, and for increasing the iodine adsorptivity.SOLUTION: A regeneration method for used activated carbon for drying used activated carbon used in water treatment, and for carrying out steam activation and regeneration includes an addition process of adding a hydrogencarbonate and/or carbonate to the used activated carbon before drying or after drying. |
