摘　　要：采用小型流化床装置对西湖底泥和四堡污泥进行燃烧实验。用原子吸收法测量污泥及不同温度燃烧产物中Cu、Cr、Cd、Hg等重金属元素,分析金属元素在燃烧过程中的排放特性。Two kinds of sludge collected from West Lake and Sibao water disposal factory of Hangzhou respectively were incinerated in the lab scale fluidized bed.The contents of several heavy metal elements,such as Cu,Cr,Cd,Pb and Hg in sludge and incineration bottom ashes from different temperatures (600℃,700℃ and 800℃),were investigated by atomic absorption spectrometry.The behaviors of heavy metal elements emission during combustion were discussed in the paper.
