According to the current situation of disposal, this paper mainly introduces the fly ash disposal technologies such as solidification/stabilization+landfill disposal, water washing+cement kiln collaborative disposal, high temperature melting/sintering disposal, compares and analyzes the advantages and disadvantages of existing technologies, and looks forward to its future development trend.
