摘　　要：利用臭氧氧化烟气中难溶性的NO为可溶性的NO2、NO3、N2O5等氮氧化物,结合相应的吸收剂可实现烟气脱硝。本文介绍了臭氧氧化脱硝机理,分析了水吸收、钙基溶液吸收、氨水溶液吸收及强碱溶液吸收四种工艺的优点和缺陷,为臭氧氧化烟气脱硝工艺研发及今后工程实践提供参考。The flue gas insoluble NO was oxidized to soluble NO2, NO3 , N2 O3 and so on using O3, combining with the corresponding absorbent to realize flue gas denitrification. The mechanism of O3 oxidation denitrification was introduced, and the advantage and defect of water absorption, calcium base solution absorption, ammonia solution absorption and strong alkali solution absorption technologies were analyzed in this paper,to provide reference for research and development and the future engineering practice of O3 oxidation flue gas denitrification process.
