摘要：
In order to obtain the pyrolysis characteristics of sewage sludge, the thermalgravimetric analysis was used to study themechanism of dried sewage sludge from Xi'an Beishiqiao Sewage Treatment Plant. The TG-DTG curves of sludge under different heating rate are obtained. The results showed that there are three periods of losting weight quickly in pyrolysis process of sludge. By Coats-Redfern exponential integration, the pyrolysis kinetic parameters - frequency factor A and the activation energy E which of the second period were obtained, and the pyrolytic dynamics calculation model of the sludge was also given.
