PROBLEM TO BE SOLVED: To provide a device for sterilizing and purifying fluid, having high sterilization and purification effects. SOLUTION: Net-like photo-catalysts 7 are arranged in plural layers vertically or slantly with respect to the direction of the flow of fluid in a treating case 4 under irradiation with UV rays. Thus, the fluid passes continuously through the meshes of the photo-catalyst 7 plural times, then the occasion when the substance to be treated comes into contact with the photo-catalyst particles increases and the efficiency of working of the photo-catalyst is raised and the sterilization and purification performance is enhanced. |
