Abstract

PURPOSE: To raise the separability of sludge by eliminating the blinding of filter medium and also by raising the stickability and separability of microorganism on the lower part of filter medium in the system in which the flow of water passing through filter medium is directed upwards in a circulated manner all the time.
CONSTITUTION: Original waster to be treated is first introduced into the circulating cylinder 2 where it is mixed with water pumped up by the pump CP from the storage tank 8 and also air through the diffusing pipe 3 from the blower B is blown into the water for the supply of oxygen. The water current passing through the circulating cylinder 2 becomes of an upward flow going from the lower part to the upper part of the filter medium 41 through the precipitate 6, and the water passing through the filter medium 41 enters the water-collecting through 5, passes through the pipe 9, and enters the storage tank 8. Then, the water over-flowing the storage tank 8 is discharged as treated water, and the biological membrane which deposits on the precipitate 6 is discharged as the sludge 7 to the outside by the pump P properly.
