摘要：
The behavior of selected heavy metals in sewage sludge during incineration was investigated in a two-stage swirl-now fluidized-bed incinerator. Leaching tests- were also carried out to evaluate the leachability of the metals in the ash discharged from the incinerator. Selected heavy metals were quantitatively retained in the output stream ash due to both the effects of a low incineration temperature and a uniform temperature distribution in the incineraton. Further, it can be round that the metals contained in the ash were highly stable.
