Description

Technical Field

[0001] The present application relates to the technical field of sewage sedimentation, and more specifically, to a sewage sedimentation tank. Background Art

[0002] Sewage sedimentation tank is an important part of sewage treatment system, used to settle suspended matter and solid particles in sewage to purify water quality. After staying in the tank for a period of time, gravity causes solid particles to settle to the bottom of the tank, forming a sludge layer, so that suspended matter in sewage can be separated and removed, purifying water quality.

[0003] Existing sewage sedimentation tanks usually adopt the principle of gravity sedimentation, which slows down the water flow rate so that the suspended matter in the sewage settles naturally in the tank. However, this traditional sedimentation method has a low sedimentation efficiency. When the amount of sludge is large, a long sedimentation time is required to settle the sludge, which is not conducive to large-scale or efficient treatment. When the sewage flow rate is fast, the sludge will enter the drain pipe with the water flow, seriously affecting the subsequent use operation.

[0004] In view of this, we propose a sewage sedimentation tank. Utility Model Content
