摘要： 钢铁行业在我国经济生产中占有重要地位，是国家的支柱性产业，但同时也是高耗能、高耗水、高污染、高碳排行业。在我国制定“双碳”发展目标的新形势下，钢铁行业水污染末端治理与生产过程结合度不够，用水用能效率仍有待提升，难以满足行业低碳发展的控制需求，亟需推进污染控制与碳减排统筹。本工作提出了“双碳”战略下钢铁行业节水减污技术发展的研究思路，通过供水-用水-废水处理-水循环利用综合统筹、污染跨介质-低碳协同控制、水污染全过程控制及智能优化、钢铁企业与城市的产-城共荣协同发展等方面，有望进一步提升对未来钢铁行业节水减污的科技支撑能力，助力钢铁行业绿色低碳发展。

Abstract: The iron and steel industry plays an important role in Chinese economic development. It is a pillar industry of our country, but also an industry with high energy and water consumption, high pollution, and high carbon emissions. Under the new situation that China has formulated the carbon peaking and carbon neutrality goal, the end treatment of wastewater pollution in the iron and steel industry is still disconnected from the production process, and the efficiency of water and energy usage still needs to be improved. It is difficult to meet the control needs of low-carbon development of the industry, so it is urgent to promote the overall planning of pollution control and carbon emission reduction. This work puts forward the research ideas for the development of water-saving and pollution-reduction technology in the iron and steel industry under this background, which concludes the comprehensive planning of water supply, water use, wastewater treatment, and water recycling, low-carbon collaborative control of water pollution across different mediums, the whole process control and intelligent optimization of wastewater pollution, the common prosperity and collaborative development of steel enterprises and local cities. It is expected to further enhance the scientific and technological support for water conservation and pollution reduction in the iron and steel industry in the future, and help the green and low-carbon development of the industry.

Key words: Iron and steel industry, Low carbon development, Cross-medium pollution, Whole process water pollution control, Water saving and pollution reduction
