PURPOSE:To easily sediment and remove sludge, by adding activated sludge to outflow water after treatment by a bacteria carrier. CONSTITUTION:Waste water is treated by suspended bacteria carriers in a fluidized tank 1 to be flowed out from the fluidized tank 1 and the excessive activated sludge generated in a second process 6 is added to the outflow water to obtain primary treated water through sedimentation and separation. The released sludge contained in the outflow water is adhered to and absorbed by added activated sludge to be brought to sludge having an excellent sedimentation property. |
