Study on biogas for the users of alpine region based on two-phase anerobic fermentation technics process

For the alpine region of household biogas fermentation period is too long, less gas situation, they proposed and designed for the rural household of two-phase anaerobic fermentation equipment. Through Reasonable technical programs, control the change of two-phase anaerobic fermentation in the acidogenic phase, to determine the course of two-phase anaerobic fermentation temperature, PH value, factors such as hydraulic retention time, to explore the alpine new model of household biogas for future cold the development of household biogas to provide technical support and reference.
