Fly ash produced by Municipal Solid Waste Incineration (MSWI) contains significant quantities of dioxins, posing a major challenge for safe disposal. Compared to other high-temperature disposal methods, low-temperature pyrolysis (<500 °C) can efficiently degrade dioxins in fly at relatively low temperatures. To better understand the effects water-washing and catalysts on dioxin decomposition during pyrolysis, this study investigates impact three different (V2O5-WO3/TiO2, Fe/C, CaO) washed (WFA). The results indicate that, despite fact that pretreatment causes enrichment WFA, toxic equivalent quantity (TEQ) within WFA remains lower identical temperature when contrasted with raw (RFA). Low-temperature carried out 250 °C is capable degrading 99.3% present water-washed ash, achieving significantly performance compared which has degradation efficiency merely 80%. Nevertheless, set 210 °C, turns be low, only reaching 29%. addition remarkably promoted °C. Among them, CaO exhibited most outstanding performance, as high 94.8%. It should emphasized catalyst ratio plays pivotal role process. Specifically, proportion not less than 10 wt.%.
