PROBLEM TO BE SOLVED: To restrain an increase in the cost required to install incidental equipment such as activated carbon adsorption equipment to the utmost. SOLUTION: The substance to be oxidized such as organic matter contained in the water which is to be treated and is introduced into a reaction tank 1 from an introduction port 2 of the water to be treated is adsorbed on a large quantity of an adsorbent 6 when the water to be treated is made to pass through an adsorbent layer 7. Ozone gas rising from an ozone injector 8 is brought into contact with the adsorbent 6 on which the substance to be oxidized is adsorbed. In other words, the substance to be oxidized in the water to be treated, the ozone gas and the adsorbent 6 are contacted with one another at the same time in the adsorbent layer 7. As a result, the effect of an advanced oxidization process (AOP) can be obtained since the adsorbent 6 exhibits a catalytic action. COPYRIGHT: (C)2005,JPO&NCIPI
