Title (EN) METHOD FOR RECOVERING PULP FIBER FROM USED HYGIENE PRODUCT
(FR) PROCÉDÉ DE RÉCUPÉRATION DE FIBRE DE PÂTE À PARTIR DE PRODUIT D’HYGIÈNE USAGÉ
(JA) 使用済み衛生用品からパルプ繊維を回収する方法
Abstract:
(EN) 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.
(FR) L'invention concerne un procédé pour récupérer efficacement une fibre de pâte à partir de produits d'hygiène usagés qui comprennent une fibre de pâte et un absorbant polymère. Ce procédé est caractérisé en ce qu'il comprend une étape consistant à introduire le produit d'hygiène usagé dans une cuve de traitement dans laquelle une solution aqueuse, ayant de l'ozone dissous dans cette dernière, a été introduite, et une étape consistant à traiter le produit d'hygiène usagé tout en infusant l'eau dans la cuve de traitement à un premier débit, à extraire la solution aqueuse de la cuve de traitement à un second débit, et à introduire un gaz contenant de l'ozone dans la solution aqueuse dans la cuve de traitement, ce qui permet de décomposer l'absorbant polymère, de réduire le poids moléculaire de ce dernier et de le rendre soluble.
(JA) パルプ繊維および高分子吸収材を含む使用済み衛生用品からパルプ繊維を効率よく回収する方法を提供する。その方法は、オゾンが溶解した水溶液の入った処理槽に使用済み衛生用品を投入する工程、および処理槽に第一の流量で水を注入するとともに、処理槽から第二の流量で水溶液を排出し、かつオゾン含有ガスを処理槽内の水溶液の中に導入しながら、使用済み衛生用品を処理し、高分子吸収材を分解し、低分子量化し、可溶化する工程を含むことを特徴とする。
