Research Progress on Comprehensive Disposal Technology of Arsenic Containing Solid Waste in Non-ferrous Smelting
The smelting process of non-ferrous metals generates a large amount of arsenic containing solid waste,posing a serious threat to the ecological environment and human health.In order to promote the popularization and development of com-prehensive disposal technology of arsenic-containing solid waste in non-ferrous smelting,this article first introduces the sources and trends of arsenic containing solid waste based on smelting processes,and analyzes in detail the properties of different types of arsenic containing solid waste;Then,based on the characteristics of arsenic containing solid waste,several common arsenic containing solid waste disposal processes were introduced,including pyrometallurgical treatment process,hydrometallurgical treatment process,and joint treatment process,as well as their respective application scenarios and bottleneck issues;Finally,focusing on the treatment challenges of alkaline arsenic containing wastewater,chemical precipitation treatment technology and evaporation crystallization treatment technology were emphasized,and possible solutions were proposed.The research content of this article has certain reference significance for understanding the pollution problem of arsenic containing solid waste,under-standing the current status of arsenic containing solid waste disposal technology,and promoting the green and sustainable devel-opment of the non-ferrous smelting industry.
