Summary of Disposal Technology and Resource Utilization Approaches of Municipal Solid Waste Incineration Fly Ash
Incineration is currently the most dominant method of municipal waste treatment,but the fly ash generated by the process contains excessive amounts of toxic and hazardous components such as heavy metals,dioxins and chlorine salts,and is recognized as hazardous waste.It mainly discusses the formation and source of fly ash,physical and chemical properties,pollution characteristics and hazards,summarizes the disposal technologies such as fly ash curing/stabilization,hydrothermal treatment,low-temperature thermal treatment,high-temperature sintering,high-temperature melting,and plasma melting,and analyzes the advantages and disadvantages of each type of technology and its application.At the same time,it introduces the resource utilization of fly ash for the preparation of cement,ceramic granules,concrete mix,glass,zeolite and geopolymer,summarizes the current situation and problems of fly ash disposal technology and resource utilization,and looks forward to the direction of future development.
