<p>PURPOSE:To continuously and efficiently perform the treatment of organic waste water, by using more than two sets of rotating disc device and by alternately performing operations of raw waste water supply and treated waste water discharge by adjusting the time. CONSTITUTION:Two sets of rotating disc device 1 and 1' are used. After a membrane is produced on the disc by means of adaptation, living waste water is supplied to rotating disc device 1 by opening stop valve 6 and closing valves 7 and 9. In this way, the disc is completely submerged under water as time passes, and then, when level gauge 11 starts working, stop valve 7 is opened and valves 6 and 10 are closed simultaneously and raw waste water supply to rotating disc unit 1' is started and, at the same time, supply to rotating disc unit 1 is stopped. Then, stop valve 9 is opened and the treated waste water in rotating disc unit 1 is discharged within a prescribed time. By alternately performing above mentioned operations raw waste water supply (aerobic conditions treatment)-(anaerobic conditions treatment)-treated waste water discharge (aerobic conditions treatment) is performed continuously.</p> |
