<p><P>PROBLEM TO BE SOLVED: To provide a treatment method and its apparatus for organic waste water wherein organic waste water is treated in activated sludge treatment, treated water is separated from solid like sludge by a filter body composed of a fibrous bundle formed by bundling multiple fibrous bodies, capable of preventing leakage of solid like sludge from the filter body, and obtaining stable and satisfactory treated water, regardless of variation of BOD load. <P>SOLUTION: Turbidity or suspended matter of the treated water is measured from which solid matter like sludge is separated by the filter body composed of a fibrous bundle formed by bundling multiple fibrous bodies. A given amount of flocculant is added to an aerator according to the measured values. The flocculant is added to the aerator when the BOD load in the aerator is 0.01kgBOD/kgMLVSS/d or less, or 0.2kgBOD/kgMLVSS/d or more. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
