To provide an anaerobic treatment apparatus capable of further efficiently eliminating organic matter from waste water that contains organic matter.
The anaerobic treatment apparatus includes a reaction tank that has granules and obtains anaerobically treated water by anaerobically treating the waste water containing organic matter, with the granules. The apparatus is constituted to discharge the anaerobically treated water to the outside of the reaction tank by allowing the anaerobically treated water to flow out of the water surface side of the reaction tank. The apparatus also includes a concentrated water producing apparatus constituted to put the anaerobically treated water discharged to the outside of the reaction tank, into an airtightly pressurized state to pressurize the granules contained in the anaerobically treated water discharged to the outside of the reaction tank and to obtain separated treated water less in granule content than the anaerobically treated water, and concentrated water more in granule content than the anaerobically treated water, by sedimentation separation from the anaerobically treated water put in the pressurized state. The apparatus is constituted to return the concentrated water to the reaction tank.
