  • The Fenton liquid-phase oxidation method was used for simultaneous desulfurization and denitrification. Firstly,the effect factors, such as H2O2 content, Fe2+ content, initial pH, ultraviolet irradiation(UV) and temperature, were investigated employing the single-factor experiments, respectively. The results indicated that the removal efficiency of SO2 and NO increased with the rise of the H2O2 content and Fe2+ concentration in the aqueous solution. Meanwhile, the variation of initial pH had great impact on the removal efficiency of SO2 and NO, and the efficiency could be improved when the UV was used. Temperature has little effect on the desulfurization efficiency however it plays a distinct role in the removal of NO. Hence, appropriate improvement of temperature could enhance the denitrification efficiency. Subsequently, the effect of SO2 on the NO removal was also studied by comparing the experimental results between separate denitrification and simultaneously desulfurization-denitrification. It was shown that the existence of SO2 slightly improved the removal efficiency of NO, and the initial removal efficiency of NO was about 80% while that of SO2 was more than 98%.
