Pig farming wastewater treatment technology at Song Vu farm.
Physicochemical technology combined with aerobic microorganisms SBR
Wastewater (Collected together with pig manure) → Collection tank → Pumping and pressing to separate manure; wastewater after separation → Intermediate tank → Biogas tank 1 → Biogas tank 2 → Sedimentation tank 1 → Sedimentation tank 2 → Conditioning tank → Flocculation – flocculation tank → Physicochemical Sedimentation tank → Selector tank → Aerobic tank SBR → Disinfection tank → Biological filter yard → Biological pond 1 → Biological pond 2 → Receiving source.
Construction process of pig farming wastewater treatment system.
Proceed to dig Biogas holes in settling ponds, finishing ponds and lay pipes
Carry out welding
