摘　　要：随着对SO2排放控制要求提高以及有效固硫技术的广泛应用,经历高温的废渣硫酸盐含量越来越高,这些高硫废渣的资源化利用越来越受到关注。本文从作为水泥原料使用的角度,分析了我国目前排放量较大的固硫灰渣、垃圾焚烧飞灰和污泥焚烧飞灰等高硫废渣的主要特性,并针对高硫废渣特性提出高硫废渣作为水泥混合材应用的一些建议。With the higher requirement of SO2 emission control and wider applications of effective desulfurization technologies, the residues formed in high temperature have much higher sulfate content. Therefore the utilization of the sulfate-rich residues has attracted more and more attention. In this paper, the fluidized bed combustion （FBC） ash and slag, municipal solid wastes incineration （MSWI） fly ash and sewage sludge ash （SSA）, as the main types of sulfate-rich residues, their characteristics are investigated in a view of using as raw components of cement. In addition, considering the characteristics of the sulfate-rich residues, the applications of them as supplementary eementitious materials of cement are proposed.
