The present invention provides a method which， in the process of manufacturing recycled pulp fibers from a mixture of pulp fibers and a high water-absorption polymer， enables efficient manufacturing of the recycled pulp fibers while properly removing the high water-absorption polymer from the pulp fibers. This method comprises: a supply step (S 19-2a) for supplying an aqueous solution containing a mixture (98) to a driving fluid supply port (DI) of an ejector (107) and simultaneously supplying， to a suction fluid supply port (AI) of the ejector， a gaseous substance (Z2) which is capable of degrading a high water-absorption polymer so as to make the degraded polymer dissolvable; and a treatment step (S19-2b) for discharging， from a mixed fluid discharge port (CO) of the ejector that is connected to a lower part of a treatment tank (105)， a mixed liquid， which is formed when the aqueous solution and the gaseous substance are mixed within the ejector， into a treatment liquid (P2) within the treatment tank， so as to lessen the high water-absorption polymer in the mixture.
