Since the requirements of sludge treatment and disposal in China is becoming more and more stringent , sludge car-bonization technology is regarded as an efficient disposal method of sludge stabilization, reduction, innocuity as compared with conventional sludge treatment technologies.Its advantages become more and more obvious and have a bright market prospect.This paper introduced the basic principles and domestic research progress of sludge carbonization technology, elaborating that sludge carbonization technology can be divided into high temperature carbonization , medium temperature carbonization and low tempera-ture carbonization based on the temperature control range and whether it is pressurized.This paper described the technical charac-teristics of each carbonization technology , comparing them in terms of operating conditions and products and analyzing the trends of carbonization technology.
