The secondary pollution brought by the biogas and bioliquid after scale pig breeding residue anaerobic fermentation is very serious. In response to this problem

Taihua pig farm works closely with Nanchang University. Under the guidance of the integration of systems engineering theory and circular economy and other theories

the farm has constructed stable supply engineering to utilize the biogas efficiently. And for the pollution of bioliquid

the farm has set up a systemic engineering for shunting

delay filtering

natural flow aerobic treating

and three-tier storing the bioliquid. Also it has set up five types of resource utilization engineering. So it has successfully realized that the resource utilization of livestock residue inner breeding region

as well as treatment of the pollution. The Taihua mode we introduced in this paper has the advantage of simple structure

easy to operate

and is particularly suitable for scale pig raising farms.
