摘要
本文简述了炼铝行业产生的大宗工业固废赤泥的化学组成、物理化学特性。基于这些特性,详细综述了通过对赤泥进行改性,制备各种环境吸附材料、纳米催化剂以及陶瓷材料,并用于石油化工产品脱硫脱氯和环境污染治理等领域。最后对赤泥固废的有效利用途径和面临的问题进行了分析。
The chemical composition and physicochemical properties of red mud,a large amount of industrial solid waste produced in aluminum smelting industry,are briefly described.Based on these characteristics,the preparation of various environmental adsorption materials,nano-catalysts and ceramic materials by modifying red mud were reviewed in detail,which were used in the fields of desulfurization and dechlorination of petrochemical products and environmental pollution control.Finally,the effective utilization ways and problems of red mud solid waste are analyzed.
