脱硝

The main component of NOx in flue gas is NO (with a volume concentration of 95%), which is difficult to dissolve in water and has poor reaction activity. 強力な酸化剤として, ozone can easily oxidize NO into high valence NO2, N2O3, N2O5, 等, and dissolve in water to generate HNO2 and HNO3. As a clean strong oxidant, ozone can quickly and effectively oxidize NO to high valence nitrogen oxides.
