<p><P>PROBLEM TO BE SOLVED: To provide a method for treating swelling in a system for an activated sludge process solving the swelling by a bactericide, complementing a decrease in process performance caused by damage to activated sludge due to the bactericide by introducing at least one or more kinds of microbes, without reducing a waste water treatment performance, and capable of swiftly and continuously suppressing the swelling. <P>SOLUTION: In the method for suppressing the swelling characterized by introducing the bactericide and at least one or more kinds of microbes to the system for the activated sludge process by leaving a space, it is preferable that the bactericide is a chlorine-based oxidation type bactericide, and further, to dose the bactericide to a sludge separation tank and/or a sludge recirculation line as a dosing place, and introduce the microbes into an aeration tank. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
