The integration of desulfurization, wet electricity, and flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied in the chemical industry for the generation of multiple nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Therefore, the application of this technology has many benefits for environmental air purification. The currently known flue gas desulfurization and denitrification technologies include PAFP ACFP、 Technologies such as soft manganese ore method, electron beam ammonia method, pulse corona method, gypsum wet process, catalytic oxidation method, microbial degradation method, etc.
