摘要

Mixed combustion is considered as an effective and sustainable sludge energy utilization technol-ogy. A full understanding of the mixed combustion characteristics of municipal solid waste and sludge and the migration characteristics of heavy metals is helpful to formulate strategies to reduce environ-mental pollution during sludge utilization. In this pa-per, the combustion characteristics of municipal waste pollutants mixed with municipal sludge and domestic waste are comprehensively studied, and the activation energy of sludge combustion is measured by model-free method. The migration characteristics of heavy metals in combustion products under the mixing ratio are also studied in detail. The results show that mixed combustion is a multi-step process, and the activation energy increases with the increase of material conversion rate, with an average activa-tion energy of 79.59kj·mol!. With the increase of combustion temperature, the gas yield increases, the tar yield first decreases gradually, while the solids increase. At the mixing ratio of 3.5, the volatile se-?sis?quence of hot heavy?ymetals?Cu
