摘　　要：针对某地区历史遗留的含铬污泥,采用了回转窑焚烧系统对其进行解毒。通过铬渣干法解毒的方法原理、技术手段等对该工程采用的铬渣干法解毒技术进行了全面的介绍,并阐述了该成套处理产品的技术创新点。通过技术创新,使含铬污泥中的Cr6+彻底还原为Cr3+,尾气达标排放,且二噁英达欧标排放,较为经济地解决了遗留铬渣的处理处置问题,为该地区的环境保护工作提供参考。By using the rotary kiln incineration system, this article detoxifies the chromium sludge which was leR in a region for historic reasons. Moreover, the article gives a comprehensive introduction to the chromium slag dry detoxification technology from the aspects of its principle of the method, the technical means, etc. , and explains the technical innovation of the sets of processing products. Through technological innovation, the sludge containing chromium Cr^6＋ is completely restored to the Cr^3＋ , thus, the exhaust emissions reach the standards, and the dioxin level reaches the European emission standard. Therefore, it disposes the chromium slag in an economic way, and is significant to the environmental protection in the region.
