<p>The utility model relates to a light-catalysed disinfecting and sterilizing device for sewage or gas, which is composed of a box body, a disinfecting cavity and an air sucking mechanism, wherein the disinfecting cavity and the air sucking mechanism are arranged in the box body which is provided with an inlet and an outlet, and the sewage or the gas is discharged from the outlet after sucked through the disinfecting cavity from the inlet of the box body. The disinfecting cavity is formed by that spacer plates which are obliquely arranged in mutual parallel are respectively arranged on the top surface and the corresponding bottom surface in the disinfecting cavity, the length of each of the spacer plates is slightly shorter than the inner height of the disinfecting cavity, an upper and a lower spacer plates are staggeringly arranged at intervals to be formed into a passage which is bent back and forth, a titanium dioxide coating layer is arranged on the surface of each of the spacer plates, and UVC type ultraviolet lamps are installed on the top surface and the bottom surface of the disinfecting cavity. Due to the facts that the passage is bent back and forth, the surface of each of the spacer plates is provided with the titanium dioxide (TiO2) coating layer, and the disinfecting ultraviolet lamps are provided, the process and the time for the sewage or the gas passing through the disinfecting cavity are extended so that the sewage or the gas is sufficiently irradiated by the ultraviolet lamps from place to place in a long disinfecting passage to be sterilized and disinfected. The decomposition of organic matter, dirt removal, deodorization and antibiosis are effectively done by using the photocatalysis of titanium dioxide. The ideal disinfecting and sterilizing effect is achieved.</p> |
