摘　　要：赤泥是炼铝工业的废料,其中含有大量的可利用资源,对赤泥减量化、无害化、资源化的研究可以从根本上解决赤泥堆积占用大量土地、潜在危害大的问题.本文通过单因素试验、多次洗脱试验以及正交试验研究了赤泥的脱碱性能,赤泥的脱碱技术可广泛应用于赤泥的预处理工艺中以达到减少赤泥危害的目的,为后续赤泥烧制高质量的砖提供了理论和技术支撑.Red mud are the waste of aluminum industry. There were huge in red mud. Researches on minimization, hazard-free treatment, and reutilization of red mud could fundamentally solve problems as field occupying and high protential risk,holding a pro-found significance. In this thesis, Single factor experiment,orthogonal test and repeatly wash-ing were employed to study dealkalization performance of red mud. The red alkaii can be widely used in red mud pre-treatment process to achieve the purpothe harm of red mud. It provides a theoretical and technical support for the subsequent tiring of high quality red mud brick.
