The municipal solid waste incineration (MSWI) fly ash has been a major problem with the rapid development of the cities in China. And the cement rotary kiln co-processing technique is accepted as an effective method to dispose detrimental heavy metals in MSWI fly ash. This study focused on presented the total leaching content and the morphological distribution of the heavy metals in cement solid samples doped with MSWI fly ash. These samples were collected from a MSWI fly ash co-processing cement rotary kiln plant. The leaching test and the sequential extraction procedure were adopted to measure the migration characteristic of As, Pb, Cu, and Zn. In addition, the leachability of clinker samples under different simulated environmental conditions was also detected to analyze the security of the cement product doped with MSWI fly ash. This work demonstrates the feasibility of the cement rotary kiln MSWI fly ash co-processing technique and provides a scientific guidance to related plant.
城市固体废弃物焚烧（MSWI）飞灰是中国城市快速发展带来的主要问题。而将水泥回转窑协同处置技术作为一种有效处理 MSWI 飞灰中有害重金属的方法已被广泛接受。本研究集中于研究掺有 MSWI 飞灰的水泥固体样品中重金属的总浸出含量和形态分布。这些样品是从 MSWI 飞灰协同处置水泥回转窑厂采集的。采用浸出试验和连续提取程序来测量 As、Pb、Cu 和 Zn 的迁移特性。此外，还检测了不同模拟环境条件下熟料样品的浸出率，以分析掺有 MSWI 飞灰的水泥产品的安全性。这项工作证明了水泥回转窑 MSWI 飞灰协同处置技术的可行性，并为相关工厂提供了科学指导。
