Abstract
Conditions of municipal sludge and wheat straw pyrolysis, that was the temperature and proportioning, were changed by experiment. The five-step continuous extraction put forward by tessier was adopted to extract numbers of heavy metals including Cu, Zn, Pb, Cd, Cr, Ni and different kinds of shapes in the carbon powder by pyrolysis. Perkin elmer analyst 700 atomic absorption spectrometer was adopted to detect the content of extraction and the change regulation of different kinds of shapes under sludge and wheat straw pyrolysis was examined. The experimental results shown that the formation of carbon powdered by pyrolysis was compared with sludge before pyrolysis.
