<P>PROBLEM TO BE SOLVED: To provide a treatment apparatus of organic matter containing wastewater in which the film filterability of an aerobic biological treatment sludge is improved, film flux is maintained high, and chemical washing frequency is reduced when the aerobic biological treatment is performed after the organic matter containing waste water is performed by anaerobic biological treatment, and the aerobically biologically treated water is performed by a membrane separation treatment. <P>SOLUTION: The treatment apparatus of organic matter containing wastewater includes: an anaerobic biological treatment tank 1 which performs the anaerobic biological treatment of the organic matter containing wastewater; an aerobic biological treatment tank 2 which performs the aerobic biological treatment of the anaerobically biologically treated water that flows out from the anaerobic biological treatment tank 1; and a membrane separator 5 which solid-liquid separates the aerobically biologically treated water of the aerobic biological treatment tank 2, and is characterized by providing a biological fixed bed 4 in the aerobic biological treatment tank 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
