Municipal solid waste incineration fly ash (MSWIFA) is rich in chlorine salt, carbon component, heavy metal and dioxin (PCDD/Fs) with high concentration. It has been listed in the national hazardous waste list. It must be safely and innocuous treated before its resource utilization and landfill. There are few studies on the pollution characteristics and treatment of msi fly ash in Macao. The pollution characteristics of toxic and harmful substances such as heavy metals and dioxins in msi fly ash were introduced in this paper. The research status of many fly ash detoxification and harm reduction technologies such as chemical agent stabilization method, cement solidification technology, heat treatment technology, flotation technology and microwave pyrolysis technology were analyzed. The research progress and existing problems in the treatment of heavy metals and dioxins in msi fly ash by the latter three technologies were elaborated emphatically, and their application prospects were prospected.
