COMPOST FERMENTATION APPARATUS OF LIVESTOCK FARMING WASTE WATER

摘要

The present invention relates to a composting fermentation device for livestock wastewater, when composting the solids of pigs in the livestock wastewater can be fermented without the addition of sawdust, chaff or lime, as well as to reduce the size of the composting fermentation facility The purpose is to make it. The present invention configured for this purpose is a vertical fermentation tank for storing and fermenting a certain amount of solids; A hollow rotating shaft installed in the longitudinal direction rotatably inside the fermentation tank; Means for driving a rotating shaft; A plurality of stirring rods installed in the transverse direction on the outer circumferential surface of the hollow rotating shaft, while a plurality of air injection holes are formed in each of the stirring rods to stir the solids by the rotation of the rotating shaft; Blowing means for forcibly blowing air to the hollow portion of the rotary shaft to inject air into the solids in the fermentation tank through the air injection hole of the stirring rod; An outlet for discharging gas in the fermentation tank; And a means for supplying a portion of the solids in the manure collected in the fermentation tank to a fermentation solid in the fermentation tank.
