Abstract:
Thermal pretreatment can improve subsequent sludge anaerobic digestion efficiency and performance of sludge dewaterability.This paper summarizes domestic and foreign studies of sludge thermal pretreatment,including thermal-alkaline,thermal-ultrasound,and thermal-oxidation,highlighting the effect of thermal pretreatment on sludge solubilization,anaerobic digestion,dewaterability,and rheological behavior.The overall energy balances of thermal pretreatment and anaerobic digestion were analyzed.Finally,the problems with the thermal pretreatment studies were discussed,and the development tendencies were presented.
Key words:  thermal pretreatment  solubilization  anaerobic digestion  combined pretreatment  energy balance
