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 treating device which can be easily maintained in a satisfactory operating state and treat a digestive gas economically without the use of a chemical or a dry desulfurization device, as well as a method for treating the digestive gas. SOLUTION: An aeration tank B is arranged right below a water wash desulfurization/decarbonation device A, and a biodesulfurization device C is arranged in a process line following the aeration tank B. The water wash desulfuriz ation/ decarbonation device A has an exhaust aperture 6 on the top and an air inlet 5 and a water drain port 10 at the bottom with a filled layer 2 for bringing air into contact with a liquid formed in the intermediate part. A water spray pipe 3 is installed between the filled layer 2 and the exhaust aperture 6. The water wash desulfurization/ decarbonation device A is connected to the aeration tank B with a water spray pipe 4. In addition, the aeration tank B has an air diffuser 12 provided at the bottom part and at the same time, an exhaust aperture 16 at the top, and the exhaust aperture 16 is connected to the biodesulfurization device C with a tubular path 25. Further, in the biodesulfurization device C, filled layers 18, 22 in which a filler with implanted microbes is packed, are arranged and an exhaust aperture 30 connected to a suction blower 33 is arranged at the bottom part.

摘要： PURPOSE:To efficiently decompose a malodorous gas without deactivating microorganisms. CONSTITUTION:This treating device includes treating chambers 2 and 2' formed in the main body 1, fixed beds 2a and 2b for decomposing the malodorous gas component packed with a packing to which microorganisms are adhered and a neutralizing line extending from the chambers 2 and 2' to water sprinklers 3a and 3b through a neutralization tank 8. The malodorous gas is introduced downwardly into the chambers 2 and 2' and brought into contact with the fixed beds 2 and 2' to remove malodsrus components.
