Abstract:
Provided is a method for efficiently recovering pulp fiber from used hygiene products that include pulp fiber and a polymer absorbent. This method is characterized by including a step for introducing the used hygiene product into a treatment tank in which an aqueous solution with ozone dissolved therein has been introduced, and a step for treating the used hygiene product while infusing water into the treatment tank at a first flow rate, extracting the aqueous solution from the treatment tank at a second flow rate and introducing a gas containing ozone into the aqueous solution in the treatment tank, thereby decomposing the polymer absorbent, lowering the molecular weight thereof, and making the same dissolvable.

Claim (Index 2):
The method according to  claim 1 , wherein\n the first flow rate R 1  (unit: L/minute) and a volume V (unit: L) of the aqueous solution inside the treatment tank satisfy formula (1):\n 0.05 \u2264R 1 /V\u2264 0.2\u2003\u2003(1).
