Electro-catalytic anaerobic digestion methane production system

The system comprises an anaerobic fermentation tank, an electric stirring rod, an electrode anode, an electrode cathode, a controllable power supply, a pH value sensor, a temperature sensor, a feeding and discharging bottle, a positive and negative rotating peristaltic pump, a gas collecting bag, a drying filter tube, a biogas flow meter, a cooling coil, a cooling water bottle, a cooling water pump, a heating pad and a control cabinet. The electrocatalytic anaerobic digestion methanogenesis system can enhance the activity and abundance of the hydrogen-philic methanogenesis bacteria in an anaerobic system, ensure that the hydrogen-producing and acetic acid-producing effects are smoothly carried out in the system, and provide hydrogen ions or hydrogen for the hydrogen-philic methanogenesis bacteria, so that the methanogenesis efficiency is remarkably enhanced, the acidity of an anaerobic treatment system is effectively balanced, and the yield of the hydrogen-philic methanogenesis bacteria is improved.
