Abstract

PURPOSE: To perform ideal solid-liquid separation in a short time by leaving the treating water subjected to an aeration treatment still for a constant time in a solid-liquid separation vessel, and removing the same after allowing suspended solids to float and separate.
CONSTITUTION: The stop valve device 14 of a solid-liquid separating vessel 13 is opened and a stop valve 16 is closed to introduce the treating water from an aerating vessel up to a constant level, after which the stop valve 14 is closed. The treating water is left still for a constant time to allow nitrifying germs to propagate and to float while adsorbing org. matter, whereby scum is removed. A scum removing device 17 moved on a rack member by means of pinions 24 is provided to the upper part of the vessel 13. The scum enters a trough 18 through the intake port 19 of the trough 18 of the device 17, and is guided automatically to a bottom wall 20a part. Thence, when a submersible pump 21 is driven, the scum is discharged via a hose 22 to the outside of the vessel 13.
