<P>PROBLEM TO BE SOLVED: To provide a method for preventing bacteria from propagating themselves in a waste water treatment apparatus, which can allow the waste water treatment apparatus to be operated stably for a long period of time by preventing bacteria from propagating themselves in each of various units arranged in the waste water treatment apparatus. <P>SOLUTION: The method for preventing bacteria from propagating themselves in the waste water treatment apparatus comprises a step of introducing at least a part of regenerated liquid waste or regenerated waste water, each of which is generated when an anion exchange unit is regenerated, into inlets of other units in the waste water treatment apparatus in the case that the waste water treatment apparatus has the anion exchange unit at the least. <P>COPYRIGHT: (C)2007,JPO&INPIT |
