This project adopts PFR process with nearly medium temperature fermentation.Besides, it uses equipment to avoid scum crusting and improve the efficiency of biogas production. The biogas is transferred by pipe network to users, at the same time biogas slurry and biogas residue are discharged into the biogas slurry pool for further use of making bio-organic fertilizer, so this project can achieve the zero release standard.

The raw materials are including human, livestock manure and straw,etc.

The benefits to environment:

1. To avoid air pollution;

2. Biogas slurry can be made organic fertilizer to improve farmland fertility;

3.The entire biogas project has no noise, which can avoid noise pollution;

4. The excess biogas in the anaerobic fermentation system will burn through the flare burning gas, which will not pollute the atmosphere;

5. The entire biogas project has no peculiar smell, no environmental pollution;

6. The bottom of the biogas slurry pool uses a special film to avoid infiltration, and has pollution-free groundwater.
