<p>PURPOSE:To perfectly treat excretion by diffusing treatment gas into air by a method wherein a gas bubble generator is provided in the vicinity of the surface layer of the supernatant liquid anaerobically treated with anaerobic bacteria and the supernatant liquid is foamed to be fed to a predetermined height before gas bubbles are collapsed. CONSTITUTION:Excretion is flowed into a treatment tank 11 to be subjected to anaerobic treatment. Anaerobic bacteria rise in the treatment tank 11 to become a supernatant liquid. A gas bubble generator 13 is provided in the vicinity of the surface layer of the supernatant liquid, and the supernatant liquid and gas become bubbles by the gas bubble generator and move through an upper bubble feed pipe 14 to be sent into a second treatment tank 15 where gas bubbles are stored. The gas bubbles rise through a flue 17 and sheared by the blades of an upper electromotive fan 16 to be diffused into air. By this method, a blower can be miniaturized to reduce power consumption.</p> |
