Multidimensional photocatalysis sewage disposal device

A multi-dimensional photocatalyst sewage treatment plant comprises a casing, an ultraviolet lamp and an aerator pipe. It is characterized in that glass particles permeable to ultraviolet light are provided in the casing, and a nanometer titanium dioxide catalyst coat is attached to the surface of said glass particles. Glass particles permeable to ultraviolet light attached with a nanometer titanium dioxide catalyst coat are added to the reaction casing, so that the nanometer titanium dioxide catalyst is well carried in the multi-dimensional photocatalyst reactor, solving the problem of adding catalyst to a photocatalyst reaction system. It is advantages by large reaction area, high light absorbing rate, and high efficiency of oxidizing treatment of organic wastewater by photocatalyst. Moreover, titanium dioxide catalyst can be separated and recovered easily. Accordingly, this device has the value of practical industrial application.
