Abstract:
(EN) Provided is a porous membrane that can be manufactured in steps which are not complicated, that is highly hydrophilic and highly water permeable, and that exhibits excellent anti-fouling properties when used in the membrane bioreactor method (MBR method). The porous membrane includes a polymer (A) and a polymer (B), wherein polymer (A) is a membrane-forming polymer and polymer (B) has a unit (b1) represented by formula (1) and a unit (b2) based on hydroxyl group-containing (meth)acrylate. In the porous membrane, the concentration (mass%) of unit (b1) is at least the concentration (mass%) of unit (b2).
(FR) L'invention concerne une membrane poreuse qui peut être fabriquée dans des étapes qui ne sont pas compliquées, qui est hautement hydrophile et hautement perméable à l'eau, et qui présente d'excellentes propriétés anti-salissures lorsqu'elle est utilisée dans le procédé de bioréacteur à membrane (procédé MBR). La membrane poreuse comprend un polymère (A) et un polymère (B), le polymère (A) étant un polymère formant une membrane et le polymère (B) ayant une unité (b1) représentée par la formule (1) et une unité (b2) basée sur un (méth)acrylate contenant un groupe hydroxyle. Dans la membrane poreuse, la concentration (% en masse) de l'unité (b1) est au moins la concentration (% en masse) de l'unité (b2).
(JA) 煩雑でない工程で製造することができ、高い親水性と透水性を有し、膜分離活性汚泥法(MBR法)に使用したときの耐ファウリング性が優れた多孔質膜を提供する。ポリマー(A)及びポリマー(B)を含む多孔質膜であって、ポリマー(A)は、膜形成ポリマーであり、ポリマー(B)は、式(1)で表される単位(b1)及び水酸基含有(メタ)アクリレートに基づく単位(b2)を有するポリマーであり、多孔質膜中の単位(b1)の濃度(質量%)が単位(b2)の濃度(質量%)以上である多孔質膜。
