赤泥在环境修复领域的应用综述

Application of Red Mud in the Field of Environmental Remediation

赤泥资源丰富,因其高比表面积而具有很强的吸附作用,在环境修复领域前景广阔。本文详细综述了赤泥在污水处理、废气处理及土壤修复等领域的国内外研究状况,指出在提高赤泥吸附性能的基础上,充分利用赤泥中的有价元素硅、铝、铁等,制备赤泥复合材料,对赤泥资源的再生利用将产生更深远的影响。

Resources of red mud are abundant, and it has a promising prospect because of its high specific surface area which results in a strong absorption. In this paper, the research status on application of the red mud in polluted water treatment, waste gas treatment and soil restoration and other areas was described in detail. It also pointed that make full use of valuable elements in the red mud such as silicon, aluminum, iron, etc to produce composite materials on the base of improving the absorption capacity of the red mud will exert profound influence on the recycling of it.
