Abstract

Abstract

Medical waste incinerator fly ash (MWIFA) has been classified as hazardous waste in China due to its special characteristics of high concentrations of chlorine salt, carbon constituents, heavy metals, and dioxins (PCDD/Fs), which may cause serious harm to environment and human health if managed and disposed improperly. There were few comprehensive studies on treatment and disposal of MWIFA. The pollution characteristics of heavy metals and dioxins in MWIFA were presented in this study. Then, the status of various treatment technologies of fly ash, such as chemical stabilization method, cement solidification, thermal treatment, hydrothermal treatment and flotation technology were reviewed. Finally, the development and disadvantage of thermal treatment, hydrothermal treatment and flotation technology in treating heavy metals and dioxins of MWIFA were described in detail, and the prospect was also predicted in the future.
