Process for biogas generation

Process for the generation of biogas, including: material handling, anaerobic fermentation, desulfurization, washing, caustic washing, dehydration, storage, power generation step, in the desulfurizing agent is added at the same time an anaerobic fermenter of the anaerobic fermentation, so that the fermentation and desulphurization together, eliminating the need for a separate desulfurization apparatus, cost savings, in addition to a first storage tank is provided and a second storage tank, second storage tank according to a first storage tank to the gas delivery pressure of the first storage tank changes. The present invention provides a gas generating process, the gas anaerobic fermentation solution is low, the quality of the supply of instability technical problems.
