<P>PROBLEM TO BE SOLVED: To provide an air diffusion device capable of achieving a sufficient efficiency of oxygen dissolution in diffusing air into water to be treated by feeding fine air bubbles stably for a long period without the occurrence of clogging of air diffusion holes. <P>SOLUTION: In diffusing the air into the water to be treated 10, the air diffusion device 2 feeds humidified air from one surface toward the other surface of an air diffusion panel consisting of a synthetic resin film molded to a sheet form and ejects the air in a humidified state from the air diffusion holes formed by the expansion of the air diffusion panel, thereby generating the fine air bubbles 100 in the water to be treated 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
