Research Progress of Metal Additives in Anaerobic Digestion
As a typical source of clean energy,biogas has attracted worldwide attention.Although biogas production technology has been well developed in many countries,how to further increase gas production is still the focus of current anaerobic fermentation biogas research.It is an important way to increase the amount of biogas produced of anaerobic fermentation by adding suitable mental ions as one kind of additive.In this paper,the research progress of metal additives in anaerobic digestion process at home and abroad was briefly introduced.
