The concentration biogas fermentation device has the following defects: 1. The structure of the device is simple, the mixing process is backward, and the volume of the monomer pool is small. 2. Serious incrustation, many faults, and the digestibility of the material is below 60%. The main reason is that the maturation sequence of the material from raw meal to semi-raw meal to relatively clinker to clinker in the fermentation device is not easy to control, which will cause About 25% of undigested raw meal is discharged. 3. The loss of microorganisms and activated sludge in biogas fermentation is serious, and the volumetric organic load of the digester is only 2-3KgCOP/m 3 /d. 4. The existing processes all use single-stage stirring, pump stirring, and propeller stirring, but they have not achieved ideal results in the application of large tank capacity.
