摘要： PROBLEM TO BE SOLVED: To provide a method for treating organic waste water and a treatment device by which conventional problems are solved, the process or means of biological treatment is improved, and sludge can be dehydrated without adding a chemical for the improvement of the dehydrating property during dehydrating the sludge. SOLUTION: The method for treating organic waste water is carried out by introducing the organic waste water into aeration tanks 1, 2, 3, 4 to aerobically treat by active sludge, subjecting the suspension liquid sent from the aeration tanks to solid liquid separation in a sedimentation tank 5, and directly or indirectly returning the sludge settled in the sedimentation tank 5 to the aeration tanks while draining and dehydrating a part of the sludge as excess sludge. The above method and the treating device are characterized by that the amount of the returned sludge in the process of returning the sludge drained from the sedimentation tank 5 is 1.5 to 10 times as the amount of the organic waste water and that the excess sludge drained from the sedimentation tank 5 is condensed and then dehydrated by a filter press type dehydrating machine 9 having an electric osmotic function without adding a chemical effective for dehydration in an effective amount.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for treating organic wastewater, for effectively reducing the generation quantity of sludge, facilitating normal solid-liquid separation in a solid-liquid separation process and enhancing the dehydration properties of excessive sludge. SOLUTION: In the method for treating organic wastewater by introducing organic wastewater into a treatment system having an aeration tank 1 and a solid-liquid separation tank 2 respectively provided to the front and rear stages thereof to subject the same to aerobic biological treatment, sludge containing spores of endospore forming bacteria is drawn out of the solid-liquid separation tank 2 to be guided to a sludge modifying tank 3 positioned in the front stage of the aeration tank 1 and subsequently guided to the aeration tank 1. In this case, the amount of sludge guided to the sludge modifying tank 3 is made twice-quintuple the amount of organic wastewater introduced into the treatment system and spores of endospore forming bacteria in sludge are germinated by organic wastewater supplied to the aeration tank 2 to be converted to nursing cells and a single or composite compound containing silicon and magnesium is added to treat organic wastewater while propagating nursing cells.
