摘要
赤泥是氧化铝工业生产的副产物,其化学成分极其复杂,属强碱性废渣。赤泥长期堆积存放将导致土壤碱化甚至污染地下水,给环境带来沉重的负担。本文简单概述了赤泥的成分与性质,介绍了赤泥在水处理领域中的应用与研究现状,指出了其存在的问题和今后的发展方向。
Red mud is by - product of alumina industrial production, its chemical composition is very complicated, it belongs to a strong alkaline residue. The long - term accumulation of red mud will lead to soil alkalization and groundwater being polluted, which brings heavy burden to the environment. In this paper, the composition and properties of red mud are introduced briefly, the research and application present situation of red mud in water treatment is introduced, and its existing problem and the future development direction are pointed out.
