Incineration is an important way of garbage disposal. The fly ash is a kind of hazardous waste, which is rich in heavy metals, dioxins and other harmful substances. At present, the main treatment and disposal technologies of fly ash include stabilization and solidification, chemical treatment, safe landfill and resource treatment. At present, the main treatment technologies have their own advantages and disadvantages. This paper summarizes the treatment and disposal methods of fly ash based on the research status at home and abroad. Among them, resource-based treatment is the main research direction in the future. It is urgent to study clean and efficient treatment technology suitable for China.
