<P>PROBLEM TO BE SOLVED: To provide a treatment method, even when manganese is made to flow into a membrane separation type activated sludge treatment tank, in which membrane separation type activated sludge treatment is stably performed without fouling the membrane. <P>SOLUTION: In the method for treating organic waste water where manganese-containing organic waste water is subjected to biological treatment in an activated sludge treatment tank, and the water subjected to the biological treatment by a membrane separation device installed in the activated sludge treatment tank is subjected to membrane separation treatment, a load on the membrane separation device is controlled on the basis of the state of manganese in the organic waste water and/or in the activated sludge treatment tank. <P>COPYRIGHT: (C)2012,JPO&INPIT |
