The invention discloses repeatedly activated carbon powder. The repeatedly activated carbon powder comprises the following raw materials by weight: 0.3 to 1 part of phosphite, 100 to 120 parts of eucalyptus powder, 50 to 60 parts of phenol, 0.6 to 1 part of phosphoric acid, 0.03 to 0.05 part of urotropine, 17 to 20 parts of a formaldehyde solution with a concentration of 15 to 17%, 2 to 3 parts of lignin, 0.1 to 0.18 part of sodium hydroxide, 20 to 30 parts of dimethyl formamide, 1 to 2 parts of magnesium chloride, 2 to 3 parts of sodium chloride, 0.8 to 1 part of boric acid, 2 to 3 parts of allyl polyethylene glycol, 0.8 to 1 part of N-sodium lauroyl sarcosine, 1 to 2 parts of dibutyl maleate, 2 to 3 parts of urea and 0.1 to 0.2 part of di-n-octyltin bis(isooctyl mercaptoacetate). According to the invention, raw fiber is added into a salt solution for activation and is then activated in a mixed solution of formaldehyde and hydrochloric acid, so activation effect can be improved and stability of formed holes is enhanced.
