| 中文摘要 | Fly ash from hazardous waste incinerators (HWIs) was characterized by higher concentration of volatile heavy metals when compared with the ash from municipal solid waste incinerators. Inspite of its high leaching potential of toxic metals and high risk of heavy metal release in landfills, few studies are currently implemented for the detoxification of HWI fly ash. The feasibility of vacuum-aided heat treatment (VAHT) for high toxic HWI fly ash was investigated to fulfil the requirements of environmental sound management of HWI fly ash. Also, the behavior of major toxic heavy metals Ba, Cd, Cr, Cu, Pb, and Zn during the treatment and their leaching properties after VAHT were studied in detail. Laboratory scale study showed that VAHT could effectively eliminate 100% of the Cd, 93.1% of the Pb, and 81.0% of the Zn under conditions of 900 degrees C, 10 Pa, and 4 h. F-test showed that pressure is the significant factor for the removal of Cd and Pb, whereas temperature is a remarkable factor for Sn and Zn. Sequential chemical extraction analysis shows that VAHT can largely remove the heavy metals that are exchangeable, bound to carbonate, and bound to Fe-Mn oxides, correspondingly decreasing the environmental leaching toxicity of heavy metals from HWI fly ash. |
