Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sand removal flocculation tank for water treatment. Background Art

[0002] Sewage treatment, as the name suggests, is the process of purifying sewage so that the water quality of sewage can meet the national emission standards. In sewage treatment, there is often a flocculation and sedimentation operation process. Flocculants need to be placed in a flocculation tank and mixed with sewage to produce a chemical reaction, so that the suspended particles in the sewage will aggregate and become larger to form flocs, thereby accelerating the aggregation of particles and achieving the purpose of solid-liquid separation.

[0003] However, the traditional flocculation tank lacks pretreatment function. When in use, sewage is generally discharged directly into the flocculation tank. If the time is too long, it will easily cause the filter screen at the bottom of the flocculation tank to be blocked, resulting in the phenomenon that the treated liquid in the flocculation tank cannot be completely discharged after the reaction is completed. Not only that, the traditional flocculation tank also lacks stirring function. When the catalyst and sewage come into contact during use, they are easily not mixed sufficiently, resulting in the phenomenon of prolonged reaction time. Utility Model Content
