<p>PROBLEM TO BE SOLVED: To settle such problems that oxygen supplied by an aeration method based on a conventional activate sludge method is low in dissolution rate and lacks in fluidity of sewage as well, therefore, is slow in propagation of micro-organisms and is full of defects such as the burden for treatment for odor an waste sludge, and the expense of chemicals. SOLUTION: Superfine air bubbles having a high dissolution rate are ejected by a underwater type ejector pump, the specified flow is bought about in a tank, water temperature is kept by utilization of remaining heat of an underwater motor and environmental factors for the propagation of micro-organisms which decompose organic material are prepared. For instance, the inside of the tank is brought to approximate to the environment of human intestines, thereby, the explosive propagation and reactive action of the micro-organisms is imparted, the organic material is decomposed and extinguished and the odor is removed with a small number of processes and in a short time. Thus, the sewage is changed to active water, which is used for deodorization of livestock barn, is added to portable water of livestock, promotes the growth thereof, further, is sprayed to farm and, thereby, is utilized for the improvement, etc., of the soil which is fully activated and relies on no agricultural chemicals, etc. Thus, the inventive development of this system which makes the waste close to zero and prevents environmental pollution is promoted.</p> |
