Mechanisms for Co-stabilization of Multiple Heavy Metals in Thermally Treated Solid Waste Systems

Hazardous heavy metals in the solid wastes pose a great threat to environment and ecosystems. Ceramic sintering technique is a promising method for achieving the excellent stabilization of heavy metals-laden solid wastes together producing useful ceramic products. However, more complicated sintering backgrounds as well as the multiple heavy metals co-existing situations in the practical solid wastes may enhance the difficulties for the stabilization of heavy metals. This study aims to explore the mechanisms for heavy metals stabilization accompanied with their stabilization efficiencies in the sintered products from the practical or simulated solid wastes sintering systems.

固体废弃物含多种有害重金属，严重威胁环境和生态系统。陶瓷烧结技术不仅可以实现含重金属工业固废的高效稳定化，同时还可将含重金属固废转化为陶瓷产品。然而，实际固体废弃物中较为复杂的组成成分以及多种重金属共存的情况，增加了固废体系中重金属稳定化的难度。本研究旨在从实际或模拟固体废弃物烧结体系中探讨各重金属稳定化机理及其在烧结陶瓷产品中的稳定化效率。
