摘　　要：分别采用水泥固化技术、聚乙烯材料固化技术、沥青固化技术对云南某厂的硫化砷渣进行固化处理。结果表明:硫化砷渣在经过沥青-水泥的二次固化后,砷的最大浸出浓度为0.105 mg/L,固化效果十分明显。Solidification treatment was carried out for arsenic sulfide residues of one Yunnan plant separately by cement solidification technology,polyethylene material solidification technology,asphalt curing technology.The results show that the maximum leaching concentration of arsenic is 0.105 mg/L after the second pitch-cement solidification of arsenic sulfide slag,which is a very effective way.
