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： PURPOSE:To obtain the maximum transferring amount of particles with the reduction in pressure loss in a transferring tube by inclining particle-ascending tube having single diameter in a transferring system where particles are transported from one fluidized bed reactor to another fluidized bed reactor. CONSTITUTION:A particle-desending tube 3 having single diameter is connected to a particle-assending tube 4 having single diameter at the lowest part between two sets of fluidized bed reactors 1, 2. The particles are transferred from one fluidized bed reactor to another fluidized bed reactor by means of the particle-desending tube 3 and the particle-ascending tube 4. When a transferring gas is introduced from the lowest part into the particle-ascending tube 4 to transfer particles, the particle-ascending tube 4 is inclined at an angle of 10-30 degrees to perpendicular, whereby the pressure loss in the particle-ascending tube 4 can be reduced and the transferring amounts of particles are maximized.

摘要： PURPOSE:To make heavy-gravity oil to dispersed spray flow and prevent clogging of a blow-out port by providing a diffusion plate in oposition to the blow-in nozzle on its axial line. CONSTITUTION:Mixed jet flow 7 of heavy-gravity oil and steam out from a blow- out port 3 hits against a diffusion plate 5 and becomes dispersed spray flows 8, part thereof are blown to the blow-out port 3. Then the carbon particles trying to deposit on the blow-out port 3 are blown away. Hence, clogging of the blow-out port 3 does not occur. In addition, direct contacting of the jet flow 7 to the opposing pipe walls and tower walls does not occur and therefore their abrasion and corrosion do not occur either. The diffusion plate 5 may be readily replaced and it is possible to select the one of various shapes depending upon the shapes, directions, etc. of the required spray flows.

摘要： PURPOSE:To reduce an initial cost without generating forth by previously using separated water by directly supplying air and foaming agent into sludge and stirring and mixing the sludge, then adding a high-polymer flocculating agent to the mixture, introducing the mixture into a flotation tank, floating the solid content in the sludge of the mixture together with the bubbles and separating the same. CONSTITUTION:The foaming agent 3 and the air 2 from an air diffuser 12 are supplied into a mixing tank 11 to which the sludge 1 is supplied. The mixture composed of the bubbles and the sludge is formed by the rotation of a stirrer 13. The bubbles/air mixture is supplied together with the high-polymer flocculating agent 4 into a line mixer 14 by which the mixture is flocculated and mixed. The flocculated mixture is introduced into the flotation tank 8. The solid content in the sludge floats together with the bubbles and is thickened in the flotation tank 8, by which the sludge is separated to the thickened sludge 9 and separated water 10. There is no need for a bubble generator according to this configuration and since the separated water is partly circulated and used to generate the bubbles, the device is simplified and the cost thereof is reduced.

摘要： PURPOSE:To cool the title gasification product with a high operating efficiency, by using a gasifier for hydrocarbons comprising a fixed bed of water gas reactive particles and an inverted cone-type cooler with a fluidized bed of fine particles. CONSTITUTION:The gasifier 1 is equipped with the inverted cone-type cooler 3 thereon, and the large particle containing dolomite, and MgO which are active for the water gas reaction are filled in the bottom of the cooler 3 to form a fixed bed. The fine particles 4, e.g. sand and zircon sand, are filled above the bed to form a fluidized bed. A gas formed in the reactor 1 at the same temperature as the gas in the bottom of the fixed bed 9 deposits no coke, and deposited coke on the bed 9 comprising the fine particles is gasified by water gas reaction. The coke in the fluidized bed 4 is peeled by the collision between the particles and discharged from above the cooler to cool the accompanying gas without coking.
