摘　　要：随着城市化的快速推进,危险废物的处理需求不断增加,传统处理方法存在污染风险和资源浪费的问题。本文对城市危险废物的分类以及现有的处理技术进行了综述,结合冶金窑炉的工作原理及其在处理危险废物方面的技术优势,基于宝钢的监测数据,分析了冶金窑炉处理废铁质包装桶的环保效益。结果表明,冶金窑炉能够在高温下彻底分解桶内残留的有害物质,同时回收铁质材料用于钢材生产。在1300℃以上的高温环境中,二噁英等持久性有机污染物被完全分解,污染物排放浓度远低于国家标准,冶金窑炉原有的配套烟气净化技术能有效去除VOCs、氯化氢等气体污染物,避免带来新的空气污染。最后,讨论了冶金窑炉技术在处理城市危险废物中的挑战及优化策略,并对其未来发展方向进行了展望。With the rapid advancement of urbanization,the demand for hazardous waste treatment continues to increase,and traditional treatment methods have problems of pollution risk and resource waste.This article reviews the classification of urban hazardous waste and existing treatment technologies.Combined with the working principle of metallurgical kilns and their technical advantages in processing hazardous waste,based on Baosteel's monitoring data,the quality of scrap iron processed by metallurgical kilns is analyzed.Environmental benefits of packaging barrels.The results show that the metallurgical kiln is able to completely decompose the harmful substances remaining in the barrel at high temperatures while recycling the ferrous materials for steel production.In high-temperature environments above 1300°C,persistent organic pollutants such as dioxins are completely decomposed,and the pollutant emission concentration is far lower than the national standard.The original supporting flue gas purification technology of metallurgical kilns can effectively remove VOCs,hydrogen chloride,etc.Gas pollutants to avoid bringing new air pollution.Finally,the challenges and optimization strategies of metallurgical kiln technology in the treatment of urban hazardous waste are discussed,and its future development direction is prospected.
