Description

Technical Field

[0001] The utility model relates to a sedimentation tank, in particular to a sewage treatment sedimentation tank. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the required water quality for discharge into a water body or reuse. Wastewater treatment is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life.

[0003] At present, when sewage is treated, a sedimentation tank is used to remove suspended solids in the water by natural sedimentation or coagulation sedimentation. Therefore, a sewage treatment sedimentation tank is needed.

[0004] When sewage is drained from the current sewage treatment sedimentation tank after sedimentation, the drainage is not thorough and cannot be carried out reasonably according to the water level of different water volumes. Since the amount of sediment in the unused water volume is different, if the amount of sediment in the tank body is less, the amount of sewage that can be discharged will be greater. At this time, the sewage near the bottom of the tank will not be convenient to be discharged, and will be discharged along with the sediment, resulting in a waste of water resources.
