中国钢铁行业“超低排放”向“减污降碳”过渡的技术思考

Technical consideration on the transition from"ultra-low emissions"to"reduction of pollution and carbon emissions"in China's iron and steel industry

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。

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.
