Photocatalysis oxidation treated high concentration organic trade waste

The invention relates to a modified loading nano composite photocatalyst which takes titanium dioxide as main part and adopts new reaction technique to degraded the organic industrial wastewater in a water processing system (see attached drawing 1 in Instruction). The main point on preparing the catalyst lies in that titanium dioxide active compounds loaded on different carriers are employed to prepare a loading photocatalyst with grain diameter of 5-40nm; meanwhile, different elements are mixed into the loading photocatalyst to reduce the composition between photoproduciton electron and cavity, which enables the catalyst to move the light absorbing wavelength thereof towards the visible regions, thus effectively improving the degradation rate of organic pollutants as a new environmental-friendly catalyst. As to the new technique of processing the organic industrial wastewater, the invention overcomes the defects that the present photocatalysts are only used for degrading the organic industrial wastewater with low concentration. The catalyst being irradiated respectively or simultaneously under sunbeam and ultraviolet light can decrease COD values of high-concentration organic industrial wastewater from 10000-40000mg / L to less than 100mg / L in short time, thus meeting the national emission standard.
