Abstract

This invention is to provide a method for treating organic waste water capable of improving the quality of treated waste water without increasing the facility cost. After organic waste water is treated biologically in a biological treatment tank 2, sludge and water in the treated waste water in the biological treatment tank 2 are separated in a sedimentation tank 4. A part of the sludge is returned to the biological treatment tank 2, while the rest of the sludge is solubilized by thermophilic bacteria in a solubilization tank 7, and thereafter the treated water is returned to the biological treatment tank 2.
