摘　　要：减污降碳协同是电解铝行业解决大气污染问题、实现深度降碳的重要路径。介绍了电解铝行业大气污染物和CO_(2)排放特征以及烟气净化和碳捕集的末端治理技术,围绕近年来电解铝的减污降碳协同控制措施,对惰性阳极材料应用、低温铝电解工艺、余热利用技术3个方向的研究进展进行了综述,并分析了可再生能源对电解铝企业减污降碳协同的支撑作用。电解铝行业大气污染物与CO_(2)排放具有同根、同源、同过程特性,但现行的末端治理技术在减污降碳方面的负协同特征正逐步显现。为实现减污降碳协同增效,在围绕源头控制、过程优化类技术开展深度研究和工业试验的同时,还需推动可再生能源与电解铝行业融合发展、实现可再生能源电力在电解铝行业的碳减排价值转化,为电解铝行业在“碳达峰”“碳中和”背景下深化绿色低碳发展提供有力支撑。Synergistic control of air pollutants and CO_(2)is an important path for the electrolytic aluminum industry to solve the air pollution problems and achieve large reduction of CO_(2).Characteristics of air pollutants and CO_(2)emissions from the electrolytic aluminum industry,as well as flue gas purification technology and carbon capture technology are introduced.Focusing on the synergistic control measures of air pollutants and CO_(2)in the electrolytic aluminum industry in recent years,the research progress of inert anodes,low-temperature aluminum electrolysis,waste heat recovery are reviewed.The role of renewable energy in supporting the synergy of pollution reduction and carbon reduction in electrolytic aluminum enterprises is analyzed.At present,air pollutants and CO_(2)emitted by the aluminum electrolysis industry come from the same source and have the same process characteristics.However,the current flue gas purification technology and CO_(2)emission reduction is showing negative synergy characteristics.In order to achieve synergies between pollution reduction and carbon reduction,it is necessary to carry out in-depth research and industrial tests on technologies related to source control and process optimization.It is also necessary to promote the integration of renewable energy and the electrolytic aluminum industry,and explore the carbon emission reduction value transformation path of renewable energy power in the aluminum industry,to provide strong support for the deepening of green and low-carbon development of aluminum industry under the background of"Carbon Peak""Carbon Neutrality".
