Abstract:

With the rapid development of industrial production,the output of industrial waste slag has been increased sharply.Due to its complex composition and potential environmental harm,the management and disposal of secondary aluminum dross have become urgent problems to be solved.The traditional secondary aluminum dross treatment technology is limited by technical bottleneck and high cost,and it is difficult to meet the current demand of environmental protection and resource recycling.In recent years,a large number of foreign studies have focused on the co-treatment technology of secondary aluminum dross and industrial waste residues.Through optimizing the ratio,regulating the reaction conditions and collaborative design strategies,the synergistic effect between waste residues has been realized,the resource recovery rate has been increased,and the waste discharge has been reduced.The feasible ways of co-treatment of secondary aluminum dross and industrial waste slag were summarized,including the recovery of valuable metals,the utilization of building materials and the application of glass ceramics.At the same time,the future development of co-treatment technology in improving the level of resource utilization of industrial waste and promoting high value conversion was prospected,and it was pointed out that this technology should be further consolidated and developed,and at the same time,efficient waste reduction could improve the resource recovery rate and the added value of treatment products.It was also suggested to develop new curing agents,promote the industrial application of co-treatment technology,and help economic circulation and industrial green transformation.

Key words: secondary aluminum dross, industrial waste residues, co-treatment, recycling
