摘　　要：经过系统的实验、中试和工业化试验研究,成功解决了气相臭氧氧化协同吸收脱硫脱硝技术涉及的同一吸收系统内同步高效脱硫脱硝,O_(3)与烟气混合强化,冒黄烟和O_(3)、SO_(3)、N_(2)O_(5)逃逸造成二次污染等技术难题。在此技术基础上,投运于某钢铁厂3#炉300m^(2)烧结机烟气处理工程,并实现连续、稳定运行,不仅实现了SO_(2)、NO_(x)和颗粒物排放浓度分别低于35mg/m^(3)、50mg/m^(3)、10mg/m^(3)的超低排放目标,而且经济性优势明显,具有广阔的推广应用前景。Through systematic experiment,pilot-scale test and industrial-scale test,some technical problems involved in the gaseous ozone oxidation and synergistic absorption technology for desulfurization and denitration were successfully solved.The technical problems included the simultaneous efficient desulfurization and denitration within the same absorption system,mixed enhancement of O_(3) and flue gas,secondary pollution caused by escaping yellow smoke,O_(3),SO_(3) and N_(2)O_(5),etc.On the basis of this technology,the flue gas treatment project for 300m2 sintering machine of 3#furnace of a steel mill was built and put into operation;and continuous and stable operation were realized.The emission concentration of SO_(2),NO_(x) and particulate matters was lower than 35 mg/m^(3),50 mg/m^(3) and 10 mg/m^(3) respectively,thus achieving the ultra-low emission targets.The technology showed obvious economic advantages and a broad prospect of popularization and application.
