摘　　要：有色行业飞速发展导致砷污染严重危及生态环境,含砷废渣的处理与处置已刻不容缓。文章对近年来含砷废渣无害化/资源化处理论文进行研究和分析,讨论了现有水泥固化/稳定化固砷技术的弊端,阐述了含砷废渣处理过程中物相变化及反应机理。讨论结果显示现有水泥固化/稳定化技术存在二次污染、资源浪费严重、固砷率低、成本高和长期稳定性未知等问题限制其推广应用。因此,文章介绍了冶金废渣协同固砷研究现状,重点论述了固化/稳定化技术的固砷机理,以期和该领域学者共同解决现存问题,为含砷废渣处理与处置技术的发展提供新视野。With the rapid development of nonferrous industry,arsenic pollution is seriously endangering the ecological environment.The proper treatment and disposal of arsenic are urgent.On the basis of the research and analysis of recent relevant studies on the harmless treatment of arsenic-containing waste,this paper studied the phase change and reaction mechanism in the treatment process of arsenic-containing waste.In accordance with the discussions and research results,the existing solidification/stabilization technology has limited applications due to the problems of low arsenic immobilization rate,high cost,and unknown long-term stability.These problems considerably limit the popularization and application of arsenic recovery and utilization technologies.The solidification/stabilization treatment of arsenic-containing waste residues has become the latest research hot spot.Therefore,this study focuses on the arsenic immobilization mechanism of various solidification/stabilization technologies.Together with other scholars,the paper aims to solve existing problems in this field and provides a new idea for the development of treatment and disposal technologies for arsenic-containing waste in the future.
