である。[Effects of the Invention] The present invention is constructed as described above, and
The contaminated air that was continuously passed through the gas passage means was sterilized and deodorized extremely efficiently by electrical treatment using electric discharge and physical or chemical treatment using a catalyst, so that it could not be treated with ozone-containing gas as in the past. Compared to methods such as mixing contaminated air with contaminated air in a contact tank, it is easier to downsize the device, and it also improves the deodorizing effect and achieves the sterilizing effect in a dramatically shorter contact time. This is a epoch-making and extremely significant invention.
