铝业赤泥污染处理的现状及前瞻

Situation and prospect of aluminum industry red mud pollution treatment

随着氧化铝工业的发展,赤泥的排放及危害日益成为严重的问题.总结了近年来我国铝工业的发展进程以及赤泥排放情况,简要评述了赤泥的基本性质,从提取有价元素、制作无机材料、环保等三个方面综述了国内外赤泥污染处理方面的研究,最后介绍了赤泥再资源化利用的最新进展,对赤泥污染处理提出了新的展望.

With the rapid development of alumina industry,it becomes increasingly important to reduce the pollution and damage caused by red mud. The development of our country aluminous industry process as well as red mud discharge was summarized;the fundamental character of the red mud was briefly judged;the research of red mud pollution treatment was overviewed from three aspects： extracting valuable elements, making inorganic materials, and environmental protection. At last, the recent advances of red mud reutilization were introduced and new prospect to red mud pollution was put forward.
