the bed smell reduce of animalhusbandry waste water microbial contact areation system

摘要

The present invention relates to a microbial contact aeration tank device for reducing the odor of pig breeding houses using livestock microorganisms, is provided with a lid 13 is formed with an upper perforation (2) in the open upper portion, attached to the bottom 17 In the contact aeration tank apparatus in which the crushed stone 4 and the solid microbial material are loaded into the cylindrical culture aeration tank 100 at which the nozzle hole at the end of the L-shaped diffuser 10 is installed at the bottom, the lid of the cylindrical culture aeration tank lid 13 is provided. The upper perforated center is provided with a protruding upper diffuser (3), the L-shaped diffuser (10) is fixed to the outer body of the culture aeration tank with the fixing heel (5), and the fixing ring 12 of the culture aeration tank It is attached to the upper side, the outer periphery network 11 is formed by the lower outer periphery, and the inner aeration of the culture aeration tank is laid with crushed stone (4) to the height of the outer perforated network and covers the filter medium (16), and the medium inner cylinder (14) After loading (not shown), It is intended to significantly reduce the odor of the livestock wastewater through the microbial contact aeration tank for reducing livestock wastewater odor, characterized in that the stacking layer (15) is further stacked with another filter net (16).
