Unfortunately,the emission of huge amounts of pollutants greatly restricts the pace of economic and social progress.Since the 13th Five- Year Plan,a series of powerful measures have been introduced at the central to the local levels to promote ultra-low emissions throughout the steel industry.With the deepening of ultra-low emissions in China's iron and steel industry,in-depth governance of the iron and steel industry is imminent.This article summarized several traditional multi-pollutant control technologies and discussed "multi-pollutant synergistic removal technology based on the magnesium method".Four new types of ultra-low emission technologies in the iron and steel industry were summarized:"multi-pollutant collection and adsorption removal technology for flue gas","multi- 收稿日期：2020-06-18 基金项目：国家重点研发计划资助项目(2017YFC0210300):国家自然科学基金资助项目(51770438)：国家自然科学基金青年科学基金资 助项目(21707007)：北京科技计划项目资助项目(Z191100009119008):北京市科技新星计划资助项目(Z171100001117084):国家移动污染 源排放控制技术工程实验室开放资金资助项目(NELM2017A14):固废资源化利用与节能建材国家重点实验室开放基金资助项目(SWR- 2019-002)中国钢铁行业超低排放之路 邢    奕1)，张文伯1)，苏    伟1) 苣，温    维1)，赵秀娟2)，于敬校3) 1) 北京科技大学能源与环境工程学院，北京 100083    2) 河北工业职业技术学院材料工程系，河北 050091    3) 河钢邯钢环保能源部，河北 056000 苣通信作者，E-mail：suwei@ustb.edu.cn 摘    要    随着中国钢铁行业超低排放的不断深入，钢铁行业的深度治理迫在眉睫. 在对几种传统的多污染物控制技术进行综 述的基础上，对“基于镁法的多污染物协同去除技术”、“烟气多污染物集并吸附脱除技术”、“多污染物中低温协同催化净化 技术”以及“烧结烟气循环技术”四种新型钢铁行业超低排放技术进行了总结，同时阐述了钢铁行业超低排放的必要性、难点 以及推动超低排放的合理化建议，并对下一步深化钢铁行业超低排放进行展望（源头治理）. 有利于推动和促进钢铁行业多 工序多污染物协同控制和治理. 关键词    钢铁行业；超低排放；协同治理；脱硫；脱硝 分类号    X511 Research of ultra-low emission technologies of the iron and steel industry in China XING Yi1) ，ZHANG Wen-bo1) ，SU Wei1) 苣 ，WEN Wei1) ，ZHAO Xiu-juan2) ，YU Jing-xiao3) 1) School of Energy and Environmental Engineering, University of Science and Technology Beijing, Beijing 100083, China 2) Material Engineering Department, Hebei College of Industry and Technology, Hebei 050091, China 3) Ministry of Environmental Protection and Energy, HBIS Handan Iron and Steel Company, Hebei 056000, China 苣 Corresponding author, E-mail: suwei@ustb.edu.cn ABSTRACT    In today ’s world, the overall output of China ’s steel industry accounts for more than 50% of the world ’s steel output; however, China ’s steel industry is dominated by lengthy processes featuring multiple steps, high energy consumption, wide variety of pollutants, and large amounts of pollutants. The steel industry is a pillar of China’s national economy, and it involves a wide range of related  industries;  thus,  it  plays  a  pivotal  role  in  the  development  of  the  national  economy.  With  the  continuous  strengthening  of  air pollution control, especially since the implementation of ultra-low emissions in the thermal power industry, the main pollutant emissions of  the  iron  and  steel  industry  have  exceeded  that  of  the  power  industry.  Thus,  becoming  the  largest  source  of  industrial  pollutants.
