PHOTOLYSIS DEVICE FOR TREATING POLLUTANT COMPRISING IMPROVED PHOTOCATALYST AND PROCESS FOR DECOMPOSING POLLUTANT BY USING THE SAME

摘要

A photolysis device and a method for decomposing pollutants using the same are provided to remove harmful materials with high efficiency using optical fiber in which double catalyst layer having improved oxidizing potential is formed. A photolysis device includes the followings: a reaction unit(5) in which one or more optical fiber(4) is formed; an ultraviolet ray supplying unit(1) irradiating an ultraviolet ray into the optical fiber of the reaction unit; and a mixing unit(6) supplying pollutants and moisture to the reaction unit. The photocatalyst layer includes a titanium dioxide optical catalyst of which specific surface area is 100 ~ 300 m/g, and the optical catalyst containing titandioxide catalyst and the catalyst having band gap energy less than 3.0 eV. The thickness of the photocatalyst layer is 2~15 mum. The diameter of the optical fiber is 0.5~5mm.
