CLEANING MODULE FOR AQUEOUS ENVIRONMENT USING FLUIDIZED BED OF TITANIA SPHERICAL POROUS BODIES AND METHOD OF PRODUCING THE SAME

PROBLEM TO BE SOLVED: To construct a practical energy minimum-type aqueous environment cleaning system by obtaining a high performance water-based environment purification module in which a self-supported photocatalyst not requiring a binder or a substrate causing lowering of the performance of a fine powder photocatalyst is used. SOLUTION: As the self-supported photocatalyst to be used without using the binder or the substrate causing lowering of the functions of the fine powder photocatalyst, titania spherical porous bodies having excellent wear resistance are produced and a fluidized bed is formed by passing water from the lower part in a module filled with the titania spherical porous bodies. the practical water-based purification module capable of efficiently decomposing and removing the pollution materials in water is obtained by irradiating the fluidized bed with ultraviolet rays.
