Description

technical field [0001] The invention belongs to the technical field of anaerobic reaction, and in particular relates to an anaerobic reaction control method and control system. Background technique [0002] Anaerobic reaction technology is a technology that can convert organic waste into energy. At present, the research of this technology is mainly concentrated in several directions such as biomass biogasification, biomass liquefaction into ethanol, biomass fuel and microbial fuel cell, biomass energy production of water gas and biomass hydrogen production. Among them, biomass biogasification is the most researched direction. Its production process is to transform biomass into a mixed gas mainly composed of methane and carbon dioxide through microbial catabolism under anaerobic and other suitable conditions. In the above transformation process, in order to ensure the effect of anaerobic reaction, it is necessary to monitor and control the parameters in the reaction process....
