The resource utilization of waste is important in the construction of an ecological civilization. Agricultural waste contains rich renewable resources and has high potential value in fertilization and energy conversion. Anaerobic digestion technology is promising for treating agricultural waste.
Anaerobic digestion refers to the way in which organic matter is decomposed into CH4, CO2, H2O and H2S by facultative bacteria and anaerobic bacteria under anaerobic conditions, which can transform solid organic matter into soluble organic matter. Not only does it have the advantages of stable processing and low operational cost, the biogas produced can also be used as clean biomass energy, reducing air pollution.
