<P>PROBLEM TO BE SOLVED: To provide an adsorption module which can reduce the differential pressure caused by water passage, can maintain an ion exchanger in a short length even when flow rate rises, and has a large ion-exchange capacity per volume, and to provide a water treatment method using the adsorption module. <P>SOLUTION: The ion adsorption module is provided with: at least a vessel having an opening into which water to be treated is caused to flow; and composite structural bodies each of which is composed of an organic porous body comprising a continuous skeleton phase and a continuous void phase, packed in the vessel, and a number of particulate bodies having a diameter of 4 to 40 μm, fixed to the surface of skeleton of the organic porous body or a number of protrusions having a size of 4 to 40 μm, formed on the surface of skeleton of the organic porous body, that is, monolithic organic porous ion exchangers each having an average diameter of pores in the moisture wet state, of 10 to 150 μm, a total pore volume of 0.5 to 5 ml/g and an ion-exchange capacity per volume in the moisture wet state, of 0.2 mg-equivalent/ml or more. <P>COPYRIGHT: (C)2011,JPO&INPIT |
