The dioxins concentration has positive a correlation with the flue gas temperature, and reaches a peak value as the temperature above 250℃. The proportion of the SO₂ concentration below 2000 mg/m³ occupies 63%, and the over 2000 mg/m³ occupies 37%. Therefore, the desulfurization efficiency should be higher than 90% and 96%, respectively. The proportion of the NO_x concentration below 300 mg/m³ is 86%, and the flue gas can be discharged directly without treatment. However, the proportion of NO_x concentration between 300 and 600 mg/m³ is 14%, and the denitration efficiency should be higher than 50%. The dioxins concentration between 1.0 and 5.0 ng TEQ/m³ has to be reduced to reach the national standard. According to the emission characteristics of high SO₂ and dioxins concentrations from the sintering flue gas, four kinds of multi-pollutant simultaneous control technologies are reviewed. Activated carbon adsorption belongs to an integrated control technology, while SDA (spray drying adsorption), MEROS (maximized emission reduction of sintering) and IOCFB (inner outer circulating fluidized bed) methods belong to collaborative control technologies based on the SO₂ absorbed by calcium-based sorbents and the dioxins adsorbed by activated carbon. Industrial applications of the four technologies are demonstrated and the removal efficiencies are compared with each other., authors=ZHU Tingyu, LIU Qing, LI Yuran, YAN Xiaomiao, QI Feng, YE Meng,

mg/m³的占37%,要求脱硫效率大于96%.NO_x排放浓度≤300 mg/m³的占86%,烟气无需脱硝可直接排放;在300~600 mg/m³之间的占14%,要求脱硝效率大于50%.二噁英排放浓度为1.0~5.0ng TEQ/m³,必须采取控制措施才能达标排放.针对烧结烟气SO₂和二噁英浓度高的特点,论述了基于活性炭吸附的活性炭法,以钙基吸收剂脱硫为主、活性炭(焦)脱二噁英为辅的SDA 法、MEROS 法、IOCFB 法等4 种多污染物协同控制技术及脱除效果., authors=朱廷钰, 刘青, 李玉然, 闫晓淼, 齐枫, 叶猛, authorsList=朱廷钰, 刘青, 李玉然, 闫晓淼, 齐枫, 叶猛, authorCompany=中国科学院过程工程研究所;湿法冶金清洁生产技术国家工程实验室, 北京 100190, correspAuthors=null,
