Abstract
A sedimenting assembly for sedimenting debris contained in a processed waste liquid in a sedimentation tank includes a plurality of partition plates extending vertically across a direction in which the processed waste liquid flows and disposed at spaced intervals in the direction, thereby defining a zigzag channel through which the processed waste liquid flows horizontally. The zigzag channel ensures a time during which to sediment the debris against a time during which the processed waste liquid flows through the zigzag channel, allowing the debris to settle reliably.
Claims8
A waste liquid treating apparatus for removing debris from a processed waste liquid discharged from a processing apparatus, the apparatus comprising:
- a sedimentation tank having side plates and a bottom plate interconnecting lower ends of the side plates;
- an inlet joined to one of the side plates, for introducing the processed waste liquid into the sedimentation tank;
- an outlet joined to another one of the side plates in confronting relation to the inlet, for discharging the processed waste liquid from the sedimentation tank;
- and
- sedimenting means disposed between the inlet and the outlet, for sedimenting debris contained in the processed waste liquid,
- wherein the sedimenting means includes a plurality of partition plates extending vertically across a direction from the inlet to the outlet and disposed at spaced intervals in the direction, the partition plates each including a through-hole, each of the through-holes on the partition plates being spaced from the side plates and the bottom plate of the sedimentation tank, wherein the through-holes on adjacent plates are at different positions such that the through-holes collectively define a zigzag channel through which the processed waste liquid flows horizontally.
