Abstract

PURPOSE: To provide a batch treating method for various kinds of waste water by the use of activated sludge, in which aeration is started after completion of supply of waste water to an aeration tank, whereby highly efficient treatment of waste water can be carried out in stable manner for a long time, while completely preventing bulking of the activated sludge.
