In this paper, the effects of different forms of sulfide on the volatilization of heavy metals (Cd, Cr, Ni, Cu, Pb, and Zn) in municipal solid waste (MSW) were investigated. The heavy metal amount and surface morphology of bottom ash were analyzed with Atomic Absorption Spectrometer (AAS) and Scanning Electron Microscope (SEM) respectively. Results showed that, compared with the organic sulfur, inorganic sulfur can more effectively immobilize the heavy metals in bottom ash in the thermal process. The presence of sulfur compounds would inhibit the volatilization of Cd, Cu and Pb during the thermal process. The inorganic sulfur would inhibit the volatilization of Cr and Ni, while the organic sulfur would increase the volatilization rates. However, the presence of sulfur compounds would increases the volatilization of heavy metals in reducing atmosphere.
Key words： heavy metals; volatilization rate; sulfur; reducing atmosphere
