摘要
赤泥是氧化铝工业生产过程中产生的高碱性废弃物。文章分析了其环境危害性,综述了其在建材、回收有价金属、废水治理及生态修复中的研究进展,指出需要加大赤泥环境危害性的监测和研究,加大赤泥的绿色处置技术研究,实现赤泥耗量大和高附加值产品方向开发,实现对环境无害的零排放和循环利用。
The red mud is a kind of waste produced in the process of aluminum oxide preparation. The environmental hazards were analyzed in this paper. The research progress in building materials, recovery of valuable metals, waste-water treatment and ecological restoration were reviewed. It was pointed out that the need to increase monitoring and control environmental hazards of the red mud, increase its green disposal research, pay more attention to the modification of the red mud. In a word, it will achieve zero discharge of harmless to the environment and recycling when a large amount of the red mud were utilized as high valueadded products.
