Abstract of invention patent:
The invention discloses a method for rapidly and efficiently degrading pollutants by ultraviolet catalytic wet oxidation at normal temperature and pressure, and designs a typical device for realizing the method. In this method, ultraviolet light, oxidant and catalyst are introduced into the reaction system, and the wet oxidation reaction is carried out under normal temperature and pressure and mild conditions by using their synergistic catalytic oxidation. Compared with the traditional catalytic wet oxidation method requiring high temperature and high pressure, the method of the invention can decompose organic pollutants in high-concentration toxic and harmful wastewater into harmless components CO2 and water at 25-80 DEG C and normal pressure, and the CODCr removal rate of various representative high-concentration organic wastewater after treatment can reach over 95%, and the biodegradability is also obviously improved. The method has the advantages of mild reaction, high treatment efficiency, complete degradation, clean and green process, energy saving and broad application prospects.
