The wastewater of pig farm is treated by aerobic and anaerobic sewage treatment system and discharged to the standard. A small amount of biogas is generated when it passes through the anaerobic reactor. Therefore, the compressed bio gas project aims at the discharge of sewage to the standard and generates biogas energy at the same time, the biogas output of this project is 2000m³/d.
