Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a speed-adjustable sedimentation tank. Background Art

[0002] Sedimentation tanks are treatment structures that use gravity sedimentation to remove suspended particles with a density greater than that of water from water. They are one of the most widely used treatment units in wastewater treatment and can be used for wastewater treatment, post-biological treatment, and deep treatment. The application of the sedimentation principle in the grit chamber can remove inorganic impurities in the water, the application of the sedimentation principle in the primary sedimentation tank can remove suspended matter and other solids in the water, the application of the sedimentation principle in the secondary sedimentation tank can remove activated sludge in the effluent of biological treatment, the application of the sedimentation principle in the concentration tank can separate the water in the sludge and concentrate the sludge, and in the field of deep treatment, the application of the sedimentation principle after the flocculation reaction of the effluent of the secondary sedimentation tank can remove suspended matter in the water.

[0003] For example, the utility model with application number 202221098683.5 discloses a high-efficiency sedimentation tank. After the sewage is precipitated multiple times in the preliminary sedimentation tank and the deep sedimentation tank, the precipitated sludge is discharged through the sludge discharge port and the sludge discharge pipe, and the precipitated sewage is output through the outlet connected to the top of the deep water outlet area, so that the discharged sewage can meet the standards.

[0004] Similar to the above application, there are still some shortcomings:

[0005] Although the high-efficiency sedimentation tank can make the discharged sewage meet the discharge standards, the high-efficiency sedimentation tank only uses natural sedimentation to separate water and impurities, and cannot adjust the sedimentation speed according to usage requirements. In addition, the deep depth of the sedimentation tank will reduce the sedimentation rate.
