| Abstract: | Huge amounts of sludge are produced in wastewater treatment, and the treatment and disposal of sewage sludge had become a rising challenge for the wastewater plant. Anaerobic digestion is a traditional method for sewage sludge treatment, which has some shortages. Recent research showed that thermal-alkaline pretreatment could enhance the anaerobic digestion of sewage sludge. In this study, the research progress of thermal-alkaline pretreatment of sludge was thoroughly reviewed, including the mechanism of thermal-alkaline pretreatment, the impact of thermal-alkaline pretreatment on the sludge properties and anaerobic digestion and the influencing factors. And the feasibility of thermal-alkaline pretreatment for enhancing anaerobic digestion of sewage sludge was discussed through energy consumption analysis. Finally, the enhancement of thermal-alkaline pretreatment on anaerobic digestion and its prospects and problems were also discussed. |
