Described were advances in the study of pollutant removal from waste gases by use of ultraviolet/hydrogen peroxide and analyzed was the effect of the strong oxidation property of the UV/H_2O_2 system on the removal of SO_2 and NO_x in simulated flue gases.Under optimum test conditions,the removal efficiency of SO_2 and NO_x by use of UV/H_2O_2 can be higher than 95%.The authors have analyzed the reaction mechanism for SO_2 and NO_x removal by the UV/H_2O_2 system and proposed a theory that the free radical reaction is the basis for oxidation and removal of pollutants.The authors also noted that the method under discussion can be used to reconstruct the existing wet type flue gas desulfuration towers and transform them into atmospheric pollution control devices capable of controlling various pollutants in flue gases.
