Abstract
PURPOSE: To save an operational cost while avoiding an excessive aeration, by aerating a sewage only at a sewage introducing period and in case where a sewage is not introduced within a determined period of time.
CONSTITUTION: An aerator in a purification vessel is controlled in such a manner to be automatically operated for a determined period of time when a sewage is introduced and when a sewage is not introduced within a determined period of time. In case where the aerator is operated at the sewage introducing period, the aerator is controlled to be driven after a determined period of time from the sewage introducing period. In the concrete, the aerator is continuously operated when a cycle timer is put ON, and intermittently operated (Ton) at determined time intervals when the cycle timer is put OFF. In this case, the aerator is automatically operated if the sewage is not introduced within a determined period of time (Toff).
