<p>PURPOSE:To reduce the treatment cost of waste water by making generated released sludge easy to sediment, by suspending inorg. particles along with org. particles having bacteria included therein. CONSTITUTION:A fluidized tank 1 has a draft tube 3 vertically provided at the center thereof and is provided with a flooding weir at the upper part thereof while a sludge separating cylinder 6 is provided between the weir 4 and the tube 3. The air diffuser 8 connected to a blower 7 is provided to the lower part of the draft tube 3 and waste water in the fluidized tank 1 is fluidized by the air diffuser 8. The treated waste water reaches the solid separating part between the flooding weir 4 and the sludge separating cylinder 6 to remove particles therein and sent to a sedimentation tank 2 where sludge is sedimented and removed to obtain treated water. Inorg. particles are received in the fluidized tank 1 other than org. particles having bacteria included therein.</p> |
