| description | To provide a manufacturing method of a recycled pulp usable as household papers from a pulp slurry including a paper sludge discharged from a paper mill as a raw material.SOLUTION: Disclosed is a manufacturing method of a recycled pulp from a pulp slurry including a paper sludge as a raw material, wherein the manufacturing method of a recycled pulp involves a pretreatment step of mixing the paper sludge with dilution water to obtain a mixed water; in the pretreatment step, a pretreatment oxidizer and/or a pretreatment alkali agent is added to the mixed water or the dilution water.SELECTED DRAWING: None
【課題】製紙工場から排出されるペーパースラッジを原料として含むパルプスラリーから家庭紙に利用可能な再生パルプの製造方法を提供する。【解決手段】ペーパースラッジを原料として含むパルプスラリーから再生パルプを製造する方法であって、上記ペーパースラッジと希釈水とを混合して混合水を得る前処理工程を有し、上記前処理工程において、前処理用酸化剤及び／又は前処理用アルカリ剤を、前記混合水又は前記希釈水に添加することを特徴とする再生パルプの製造方法。【選択図】なし |
