摘　　要：以固废铁砷渣为铁源,开展了有色冶炼砷碱渣与铁砷渣的共处理研究。在Fe/As摩尔比为1.2、温度150℃、pH为0.3和反应时间12 h的条件下,As的去除率达到87.53%,稳定性符合EPA的监管限制。研究结果表明,以“以废治废”的理念实现了砷碱渣与铁砷渣的共处理,还可为有色冶炼企业绿色高效发展提供有力的技术支撑。The co-treatment of arsenic alkali residue and iron arsenic residue in nonferrous smelting was studied with iron arsenic residue(Fe-bearing solid waste)as iron source.Under the conditions including Fe/As molar ratio of 1.2,temperature of 150℃,pH value of 0.3 and reaction time of 12 hours,the removal rate of As is 87.53%,and the stability meets EPA regulatory limits.The results show that the co-treatment of arsenic alkali residue and iron arsenic residue is realized with the concept of“treating waste with waste”,which also provides strong technical support for the green and efficient development of non-ferrous metallurgical enterprises.
