Abstract: With the development of waste water treatment market, the production of municipal sludge is increasing year by year. In order to achieve the sludge reduction 、stabilization、harmless and resource utilization, sludge carbonization technology is becoming more and more applications in engineering cases. This paper describes about municipal sludge in carbonization process, such as different sludge products are produced at different stages with the change of temperature; the temperature conditions corresponding to pyrolysis reaction of different organic matter components in sludge; the influence of the length of carbonization furnace on the carbonization reaction temperature; and the selection analysis about heat source.

Key Words: Municipal sludge; Carbonization process; Carbonization temperature; Heat source selection
