<P>PROBLEM TO BE SOLVED: To provide a disinfection layer device for efficiently disinfecting pathogenic bacteria existing agricultural service water and nutritious liquid to be used especially in hydroponics. <P>SOLUTION: This disinfection layer device 10 is made of a container 11, a disinfection layer 12, a conduit pipe 14, a drainage pipe 15, a disinfecting sheet 16, baffle plates 17 and 18, and a faucet socket 19. The disinfection layer is formed by baking in a doughnut shape a mixed raw material of a phosphate-based antibacterial agent supporting a metal having antibacterial effect, such as silver and copper, an inorganic binder, and irregular shape granular ceramics. The disinfection layer and the baffle plate are alternatively laminated in the container, the conduit pipe and the drainage pipe are inserted into through holes formed centrally in the disinfection layer, and a container inner wall and the suspended part of the drainage pipe are covered with the disinfecting sheet. Since agricultural circulating water 13 circulating in the disinfection layer device thoroughly prevails in the disinfection layer and the disinfecting sheet, and the disinfection layer contains irregular shape granular ceramics, the contact area of the circulating water is widened, and pathogenic bacteria in liquid are efficiently disinfected. <P>COPYRIGHT: (C)2011,JPO&INPIT |
