摘　　要：烟气中所含的二氧化硫(SO2),氮氧化物(NOx),重金属汞(Hg)等污染物都能对人体健康及周围环境产生危害.本文综述了臭氧法应用于烟气净化的研究进展、工业应用及反应机理,探讨了臭氧同时脱硫脱硝脱汞的主要影响因素,介绍了臭氧发生技术的研究现状,并对臭氧应用于烟气净化进行了经济性分析,认为臭氧法脱除烟气中的多种污染物具有广泛的应用前景.Sulfur dioxide（ SO2）,nitrogen oxides（ NOx）,mercury（ Hg） and other pollutants from flue gas are harmful to human health and the surrounding environment. This paper provided a comprehensive review on research progress of ozone application in flue gas purification, its industrialization and the reaction mechanisms during the process. Meanwhile,the main factors affecting simultaneous removal of SO2,NOxand Hg by ozone were discussed as well. Moreover,the research status of ozone generation technology and the cost analysis of ozone utilization in flue gas purification were proposed. Removal of various pollutants from flue gas by ozone was supposed to be a promising pollution control technology.
