Research on Process Control of High-Temperature Anaerobic Digestion System for High-Solid Sludge
Anaerobic digestion is one of the mainstream technologies for sludge treatment,which can convert organic carbon in sludge into methane.The high-temperature and high-solid content anaerobic digestion process has advantages such as high operating efficiency,high load,and reduced land occupation,compared with the medium-temperature and low-solid content anaerobic digestion process,it has some specific technical requirements in terms of control.Based on the operational experience of engineering cases,an analysis is conducted on the control of the high-temperature and high-solid content anaerobic digestion process,and a comprehensive review is conducted from the aspects of sludge control,process parameter control,operation management,and safety maintenance,providing guidance for the stable operation of the process.
