Inflating device for biological oxidation tank

The utility model relates to an inflating device for a biological oxidation tank, and belongs to a device used in a biological oxidation process. The inflation pipeline is connected with the gas distribution pipeline, gas distribution holes are evenly formed in the lower portion of the gas distribution pipeline, and the water vapor pipeline is communicated with the side face of the inflation pipeline. The device has the advantages that the structure is novel, and water mist entering the inflation pipeline from the water vapor pipeline enters the gas distribution pipeline together with gas in the inflation pipeline and then uniformly enters the bottom of the oxidation tank from the gas distribution holes. Water mist entering the gas distribution pipeline can keep the inner walls of the gasdistribution holes moist; the solid-liquid-gas separation device is simple to operate, easy to implement, suitable for a biological oxidation tank and a reactor, wide in application prospect, and goodin market value and econo
