Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a device for reducing water flow noise in a secondary sedimentation tank. Background Art

[0002] In the modern sewage treatment process, the secondary sedimentation tank is a crucial link. The secondary sedimentation tank is a device used for solid-liquid separation, mainly used to treat suspended particles in sewage. It is usually located in the primary treatment stage of the sewage treatment plant and is responsible for separating the solid matter in the sewage from the water. The secondary sedimentation tank uses gravity and sedimentation principles to make the solid particles settle to the bottom of the tank, and then the clean water flows out from the top of the tank, thereby achieving solid-liquid separation.

[0003] When the secondary sedimentation tank is in use, water will flow from the outlet hole on the sedimentation tank to the inside of the drainage ditch. The water in the drainage ditch is discharged through the outlet trough. When the water level in the drainage ditch is too low, the height difference between the outlet hole and the water surface in the drainage ditch is large. When the water flows out through the outlet hole and falls into the drainage ditch, a lot of noise will be generated due to the height difference, which will have an adverse impact on the production and life of people around.

[0004] Therefore, a device for reducing the water flow noise in the secondary sedimentation tank is needed to reduce the water flow noise in the secondary sedimentation tank and avoid the noise from affecting others. Utility Model Content
