waste such as waste water and kitchen waste enters the shell 1 through the feeding hole 101, sludge is placed at the bottom of the reaction cavity 11, the sludge contains a large number of microorganisms, and the microorganisms can decompose the waste in the reaction cavity 11 to generate methane, carbon monoxide and other gases.

Wherein, be equipped with stirring subassembly 5 in the reaction chamber 11 with the discarded object in the stirring reaction chamber 11, anode plate and negative plate are all established on stirring subassembly 5, and stirring subassembly 5 drives anode plate 21 and negative plate 22 rotatory for anode plate 21 and negative plate 22 can contact with the discarded object of different positions in the reaction chamber 11. When the power is supplied, the surface of the anode plate 21 undergoes a reduction reaction, the surface of the cathode plate 22 undergoes an oxidation reaction, the anode plate 21 and the cathode plate 22 undergo electron transfer, and electrons move from the anode plate 21 to the cathode plate 22 to generate an electric potential, which improves the decomposition capability of microorganisms. That is, the potential increases the decomposition ability of microorganisms near the anode plate 21, the decomposition ability of microorganisms near the cathode plate 22, and the microorganisms between the anode plate 21 and the cathode plate 22, i.e., in the above-described region, are more active, which ultimately improves the performance of the stirred-electrode anaerobic reactor and the efficiency of anaerobic digestion.

Therefore, the stirred electrode anaerobic reactor 100 according to the present novel embodiment has good performance, and can improve the community structure of microorganisms and strengthen the anaerobic digestion process of microorganisms, thereby improving the decomposition efficiency of the stirred electrode anaerobic reactor 100.
