PURPOSE: Provided is a device for purifying highly concentrated organic waste water, which permits the waste water to be treated completely with no need of additional incineration or embedding treatment. CONSTITUTION: The device for purifying highly concentrated organic waste water containing a great amount of solid substances comprises: an automatic compositing system(1), in which the waste water is passed through a fermentation bed(110) to be filtered, fermented in an anaerobic manner and then purified, thereby discharging leachate from which the solid substances are separated; a membrane-attached bio-reaction tank system(2), through which the leachate discharged from the automatic compositing system(1) is passed in order to remove organic substances, nitrogen, phosphorus and E.coli contained in the leachate; and a reverse osmosis membrane system(3), through which the primarily purified water treated in the bio-reaction tank system(2) is passed in order to remove hardly decomposable organic substances and colors present in the water. |
