    摘要: A deinking method using a cellulase which enables the load upon the environment to be reduced; and an evaluation method whereby a cellulase effective in deinking and the effective addition level of the cellulase can be appropriately determined. By proposing pulp-swelling activity (PSA) that elevates the water-retention value of pulp after pulp is reacted with cellulase, it becomes possible to select an enzyme that is effective in cellulase-deinking treatment without lowering the paper strength and to determine the effective enzyme dosage. Namely, a method of deinking waste paper is provided wherein the selection of an effective cellulase and the optimization of the enzyme dosage with the use of PSA as an indication make it possible to minimize the cellulase addition level and lessen the amount of the deinking agent.

    摘要: A mixing device in the form of a centrifugal pump is used to mix gas (typically air) with liquid (typically effluent water, dispersion water, or waste paper pulp suspension, etc.). The pump is provided with a common inlet conduit for both the liquid and the gas so that liquid and gas flow freely and in an arbitrary ratio into the pump, that is there is no controlling or adjusting of the flows. The gas is allowed to either dissolve in the liquid or be mixed as small bubbles with the liquid, and any surplus gas is separated from the mixing device (e.g. by holes in the pump impeller leading to a rear portion of the pump which is attached to a vacuum source, such as a liquid ring pump). The liquid and gas dissolved therein, and small bubbles mixed therein, are discharged from the mixing device at a pressure that is raised from the inlet pressure, due to the action of the impeller, which pressure development enhances the dissolution of gas in the liquid. Treatment chemicals, such as flotation-enhancing chemicals, can be added to the liquid before it enters the centrifugal pump, and the outlet from the pump may be connected to a flotation tank or the like.

    摘要: A process for increasing a degree of whiteness of paper pulp may include bring paper fiber pulp, which may at least partially include printed waste paper, into a suspension with water. The suspension may be mixed with bleaching aids and bleaching chemicals. The bleaching chemicals may preferably contain molecular oxygen. Intensely mechanically treating the pulp, e.g., at at least 20 kWh/to, prior to bleaching the pulp suspension. The bleaching period may take at least 10 minutes, with a pressure above the atmospheric pressure being exerted during the bleaching. After bleaching, a major portion of remaining color print particles may be removed from the bleached pulp.
