Abstract:
(EN) An adsorption member having a porous ceramic honeycomb structure including a plurality of flow channels separated by porous partition walls and extending in an axial direction, wherein water to be treated is passed through the plurality of flow channels so that foreign matter within the water to be treated is adsorbed and removed. The adsorption member is characterized in that: in the flow channels, the side into which the to-be-treated water flows and the side from which the treated water flows are alternately sealed; the partition walls have connection holes through which the flow channels are connected; the partition walls are formed of a base material made of porous ceramic, and metal oxide particles fixed to at least a portion of the inner surfaces of the communication holes and the surface of the base material; and the total volume of pores having a pore diameter of 10-200 nm as measured by mercury intrusion is 0.1% or more per apparent volume of the partition walls.
(FR) Elément d'adsorption ayant une structure en nid d'abeille de céramique poreuse comportant une pluralité de canaux d'écoulement séparés par des parois de séparation poreuses et s'étendant dans une direction axiale, l'eau à traiter empruntant les nombreux canaux d'écoulement, de telle sorte que les impuretés de l'eau à traiter soient adsorbées et retirées. L'élément d'adsorption est caractérisé en ce que : dans les canaux d'écoulement, le côté dans lequel s'écoule l'eau à traiter et le côté duquel s'écoule les flux d'eau traités sont scellés en alternance ; les parois de séparation comportent des trous de raccordement auxquels sont reliés les canaux d'écoulement ; les parois de séparation sont constituées d'un matériau de base constitué de céramique poreuse, de particules d'oxyde métallique fixées à au moins une partie des surfaces internes des trous de communication et de la surface du matériau de base ; et le volume total des pores d'un diamètre de 10 à 200 nm, tel que mesuré par intrusion de mercure, est de 0,1 % minimum par volume apparent des parois de séparation.
(JA) 多孔質の隔壁に仕切られた軸方向に延びる複数の流路を備え、前記複数の流路に被処理水を通過させて前記被処理水内の異物を吸着除去する多孔質セラミックハニカム構造体からなる吸着部材であって、前記流路は、被処理水流入側又は処理水流出側が交互に目封止されており、前記隔壁は、前記流路間を接続する連通孔を有し、多孔質セラミックからなる基材と、前記基材の表面及び連通孔内面の少なくとも一部に固定された金属酸化物の粒子とで構成されており、水銀圧入法で測定した10~200 nmの細孔径を有する全細孔容積が、前記隔壁の見かけ体積当たり0.1%以上であることを特徴とする吸着部材。
