一种对含重金属的残余物热处理的方法在一多床炉中完成,该炉分为三区,每区包括几个叠层。所述方法包括:将重金属残余物连续供给多床炉的第一区的顶层,逐渐将残余物转移到第二区并且在转移期间被干燥;将还原剂和脱硫剂连续供给第二区的顶层,还原剂和脱硫剂与残余物混合,加热到约 One method of heat treatment of heavy metal-containing residues is accomplished in a multi-bed furnace which is divided into three zones, each zone comprising several laminates. The method comprises continuously feeding the heavy metal residue to the top layer of the first zone of the multi-bed furnace, gradually transferring the residue to the second zone and being dried during the transfer, supplying the reducing agent and the desulfurization agent continuously to the top of the second zone The reductant and desulfurizer are mixed with the residue and heated to approx
