| Abstract: |
| As the main solid waste in aluminum electrolysis industry, electrode waste (including overhaul slag, anode carbon residue, etc.) not only contains harmful components such as fluoride and cyanide, but also contains valuable components such as high-quality carbon and electrolytes. It has the dual attributes of hazardous solid waste and secondary resources, so its comprehensive disposal can not only realize resource recycling and turn waste into treasure, but also effectively alleviate the environmental pollution caused by it. The research status of comprehensive disposal of electrode waste residues in electrolytic aluminum industry were reviewed with the main lines of harmless disposal, resource recovery and resource utilization. At the same time, the main problems of current technical methods were pointed out, and reasonable suggestions for development direction of electrode waste disposal in electrolytic aluminum industry were put forward. It can provide a reference for the comprehensive disposal of electrode waste residues in electrolytic aluminum industry, and has reference significance for green and sustainable development of electrolytic aluminum industry in China. |
