摘要： 钢铁行业是我国国民经济的重要基础产业，但同时也是我国污-碳排放量最大的工业行业。2019年4月，五部委联合印发了《关于推进实施钢铁行业超低排放的意见》，率先引领了工业烟气超低排放，我国钢铁行业大气污染排放量实现了大幅削减。“十四五”以来，在“双碳”背景下，随着减污降碳的提出，现有超低排放技术所带来的碳增量效应问题逐渐凸显，又对钢铁行业带来了新的技术需求。本工作阐述了我国钢铁行业超低排放的技术进展，归纳了钢铁行业减污降碳发展方向，并提出了未来钢铁行业绿色低碳发展建议，为推动中国钢铁行业的高质量绿色发展提供参考。

关键词: 钢铁行业, 超低排放, 减污降碳, 全过程控制

Abstract: The iron and steel industry plays an important role in China's national economy, and it is also the largest pollution-carbon emission in China. In April 2019, five ministries and commissions jointly issued the "Opinions on Promoting the Implementation of Ultra-low Emissions in the Iron and Steel Industry", leading to a beginning of ultra-low emissions for industrial flue gas, and the air pollution emissions of China's steel industry achieved a significant reduction. Since the "14th Five-Year Plan", under the background of carbon peaking and carbon neutrality, with the proposal of pollution and carbon reduction, the problem of carbon incremental effect caused by ultra-low emission technologies has gradually become prominent, which has brought new technological needs to the steel industry. This work expounds the technological progress of ultra-low emissions in China's steel industry, summarizes the development direction of pollution and carbon reduction in the steel industry, and puts forward suggestions for the green and low-carbon development of the steel industry in the future, providing a reference for promoting the high-quality green development of China's steel industry.

Key words: iron and steel industry, ultra-low emission, pollution and carbon reduction, whole process control
