摘　　要：针对某铜冶炼厂的固废渣进行了砷元素的物质流分析和环境属性研究,结果表明,含砷固废渣主要是硫化砷渣、铁砷渣及尾矿渣,含砷固废渣的酸可提取态占比较高,属于危险固废,需要无害化处置。Material flow analysis (MFA) and environmental attributes of arsenic of slag-bearing arsenic in a certain copper smelter factory were investigated in detail. The results showed that the main components of arsenic-containing solid waste residue were mainly composed of arsenic sulfide slag, iron arsenic slag and tail slag. Arsenic containing solid waste residue belongs to hazardous solid waste and needs harmless disposal because of the high proportion of soluble substances.
