摘要
铝灰是铝工业产生的一种危险固体废弃物,含有金属铝和氧化铝等成分,具有较高的回收与利用价值.铝灰的类型不同,其利用方式也不同.国内外研究显示,一次铝灰主要用于回收金属铝,二次铝灰主要用于制备聚合氯化铝和氧化铝等材料.通过总结国内外铝灰综合利用研究现状,对铝灰的研究提出建议,期待铝灰综合利用能取得进一步的发展.
Aluminum ash is a kind of dangerous solid waste produced by aluminium industry,which contains metal aluminium and alumina,and has high recycling and utilization value.Different types of aluminium ash have different utilization modes.Domestic and foreign research shows that primary alumin ium ash is mainly used to recover metal aluminium,secondary aluminium ash is mainly used to prepare polyaluminium chloride and alumina materials.By summarizing the research status of comprehensive utilization of aluminium ash at home and abroad,this paper puts forward some suggestions on the re search of aluminium ash,expecting further development of comprehensive utilization of aluminium ash and making greater contribution to the development of aluminium industry.
