Abstract
A method and an apparatus for treating an organic waste water capable of deodorizing an exhaust gas diffused into an atmosphere is provided, wherein heat energy loss is small and the amount of an organic or inorganic nitrogen compounds in an effluent from the apparatus is low. In the method of the present invention, an organic waste water is nitrified in a nitrification device 8, denitrified in a denitrification device 9, and subjected to an aerobic biological treatment in an aeration tank 10, and then the treated mixture is solid-liquid separated in a solid-liquid separation device 3. A portion of an excess sludge separated in solid-liquid separation device 3 is solubilized at a high temperature in a solubilization device 6, and the solution after a solubilization treatment is returned to denitrification device 9 and a gas exhausted from solubilization device 6 is charged into nitrification device 8.
