Co-combustion of sedum plumbizincicola and sewage sludge was performed in a tubular furnace. The influence of experimental conditions on the partitioning of Zn, Cd, and Pb was investigated. The results showed that 30% sewage sludge was proposed as the optimal ratio for the co-combustion as a compromise between low calorific value and high amount of heavy metal remained in the bottom ash. High temperature increased the volatilization degree of heavy metals, among which the performance of Cd and Pb was obvious than Zn. Rising oxygen concentration was beneficial to the formation of heavy metal compounds, and the effect of oxygen on Zn was the most pronounced. Thermodynamic equilibrium calculation was carried out to forecast heavy metal compounds. The results demonstrated that Zn, Cd, and Pb mainly generated ZnAl₂O₄, CdSiO₃ and PbSiO₃ in solid phase, which are partly confirmed by X-ray diffraction (XRD). The promising results offered a great possibility of heavy metal immobilization, indicating the combustion of Sedum plumbizincicola with sewage sludge is an effective way for waste disposal.

景天景天和污水污泥的共燃烧在管式炉中进行。研究了实验条件对Zn，Cd和Pb分配的影响。结果表明，建议采用30％的污泥作为混合燃烧的最佳比例，因为这是低热值和残渣中残留的大量重金属之间的折衷方案。高温增加了重金属的挥发度，其中Cd和Pb的性能明显优于Zn。升高的氧浓度有利于重金属化合物的形成，并且氧对Zn的影响最明显。进行热力学平衡计算以预测重金属化合物。结果表明，Zn，Cd和Pb主要产生ZnAl _2。固相中的O ₄，CdSiO ₃和PbSiO ₃部分通过X射线衍射（XRD）确认。有希望的结果提供了重金属固定化的巨大可能性，表明用污水污泥燃烧景天景天是废物处理的有效方法。
