Treatment of Methyl Orange by Photocatalysis Floating Bed

A novel photocatalysis floating bed reactor was prepared to study for the degradation of textile wastewater. The reactor was assembled by short quartz tube loaded TiO2 film, showing a good catalytic activity. The decolorization rate of methyl orange can reach 98.7% by the photocatalysis floating bed reactor under UV light irradiation for 8 hours. Scanning electron microscopy and EDS were used to characterize the structure of the photocatalyst. The results indicate that the TiO2 films of 1 μm were loaded on short quartz tube in the photocatalysis floating bed reactor.
