Abstract

PURPOSE: To ensure the returning of the required amount of active sludge by a method wherein a siphone pipe is installed between a floating sludge separating tank and an active sludge recovering tank in the water treatment equipment, so that the active sludge is taken by the action of siphone.
CONSTITUTION: In the water treatment equipment having a unit 4 to float and separate the active sludge, one end of a reverse-U type siphone pipe 18 is opened to the floated sludge layer in the separation tank 11, and the other end is opened to the active sludge recovering tank 12. At the downstream of the recovering tank 12, provided is a reservoir 5 connecting to the naturally flowing pipe route. The sludge is returned by the return unit 23 which is run according to variations in the load of pollution in a treating unit 9. At this time, the sludge is forcedly sucked by the siphone action from the separating tank 11 to the recovering tank 12 until the returned amount has caused the balance between the recovery tank 12 and the reservoir 5 with respect to the active sludge level. This ensures the active sludge to be returned in the required amount.
