中文摘要: 采用以废治废的思路，以砷碱渣为碱源加入到高砷锑氧粉中共焙烧，通过研究挥发气氛、烟尘及焙烧渣中组成成分和As、Sb含量，分析As、Sb转化迁移机理。研究表明，高砷锑氧粉和砷碱渣的共焙烧，能显著减少砷、锑的挥发；当高砷锑氧粉和砷碱渣的质量配比为1︰1时，砷的固化率由10%提高到85%；砷主要以Na3AsO4、NaAsO2、As2O5的形式固定在焙烧渣中，锑主要以NaSbO3、NaSbO2的形式固定在焙烧渣中。
Abstract:With idea of treating the wastes with wastes, arsenic-alkali residue was used as alkali source and co-sintered with As-Sb-bearing dust. As and Sb content, and composition in volatilization atmosphere, dust and roasting residue were investigated to analyze migration and transformation mechanism of As and Sb. The results shows that co-sintering of As-Sb-bearing dust and arsenic-alkali residue can effectively reduce volatile of As and Sb. The solidifying efficiency of As is up to 85% when mass ratio of As-Sb-bearing dust and arsenic-alkali residue is 1︰1. As is mainly solidified as the form of Na3AsO4, NaAsO2, and As2O5, while Sb is mainly solidified as the form of NaSbO3 and NaSbO2.
