PROBLEM TO BE SOLVED: To provide an adsorption module capable of reducing a differential pressure caused by water passage, and maintaining an ion exchanger in a short length even when a flow rate is raised, and having a large ion-exchange capacity per volume, and to provide a water treatment method.SOLUTION: An ion adsorption module includes: a container having an opening through which at least water to be treated flows in; and an organic porous ion exchanger which is a continuous macroporous structure in which bubble-shaped macropores filled in the container are superposed on one another and the superposed portions form openings having an average diameter of 30-300 μm in a water-wet state, has a total pore volume of 0.5-5 ml/g and an ion exchange capacity per volume in the water-wet state of 0.4-5 mg equivalent/ml, with the area of a skeleton portion appearing on a cross section in the SEM image of a cut surface of the continuous macroporous structure (a dry body) occupying 25-50% of the image area. |
