| description | To provide: a catalyst for water treatment capable of maintaining a contact oxidation ability of dissolved manganese even when a water flow rate is increased, sufficiently insolubilizing dissolved manganese, and reducing the residual amount of manganese in treated water; and a water treatment system and a water treatment method using the catalyst for water treatment.SOLUTION: A catalyst 1 for water treatment includes a base material 2 and a catalyst layer 3 provided on at least a part of a surface of the base material 2, in which the catalyst layer 3 contains manganese dioxide and the true specific gravity thereof is 5.1 g/mL or more. The water treatment system has a reaction tank filled with the catalyst 1 for water treatment. A water treatment method brings the catalyst 1 for water treatment into contact with treated water containing dissolved manganese.SELECTED DRAWING: Figure 1
【課題】通水速度を高速化した場合でも溶解性マンガンの接触酸化能力を維持でき、溶解性マンガンを充分に不溶化でき、処理水中のマンガンの残存量を低減できる水処理用触媒；前記水処理用触媒を用いた水処理システム及び水処理方法を提供する。【解決手段】基材２と、基材２の少なくとも一部の表面に設けられた触媒層３とを有する触媒であって、触媒層３は二酸化マンガンを含み、かつ、触媒の真比重が５．１ｇ／ｍＬ以上である水処理用触媒１；水処理用触媒１が充填された反応槽を備える水処理システム；溶解性マンガンを含む被処理水と水処理用触媒１とを接触させる水処理方法。【選択図】図１ |
