APPARATUS FOR GARBAGE DRAINAGE TREATMENT AND METHOD FOR OPERATING THE SAME

PROBLEM TO BE SOLVED: To treat corresponding to the inflow of drainage and to cut treatment power expense by a method in which crushed garbage is piping-transported with water, solids is recovered in a solid-liquid separation part, drainage is treated with aerobic microorganisms, and the treatment is done in accordance with the inflow of the drainage to a drainage treatment part. SOLUTION: Garbage crushed by a crusher 1 is led into a garbage drainage storage tank 2. The stored drainage is sent to a precipitation separation tank 5, the crushed garbage separated here is treated in an aerobic organism treatment tank 7, while the drainage is treated in a drainage aerobic organism treatment tank 8. The liquid level of the tank 2 is controlled by the level signal of a level gauge 9 set in the tank 2 to be kept in a set level range, and the air diffuser 11 of the tank 8 is controlled. Preferably, the operation of a blower 11 is controlled to stop after the air diffusion has been continued for 1/3-12hr since the stop of the inflow of the drainage into the tank 7 corresponding to the operation of a quantitative transfer pump 3.
