Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment tank. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. When treating sewage, flocculation is often used. Flocculants are added to the sewage and stirred to make the suspended particles in the sewage gather to form flocs, thereby accelerating the aggregation of particles and achieving the purpose of solid-liquid separation.

[0003] For example, a patent document with publication number CN217921721U discloses a sewage treatment tank, including a treatment tank body, wherein an outlet pipe is installed at the middle position of the bottom end of the treatment tank body, support columns are equidistantly provided at the bottom end of the treatment tank body, a partition is installed inside the treatment tank body, a through hole is opened in the middle position of the partition, and a collecting cylinder located above the partition is provided inside the treatment tank body. This design realizes the stirring of sewage and the scraping of the inner wall of the collecting cylinder to prevent flocculants from adhering to the inner wall of the collecting cylinder, and at the same time cooperates with the action of the lifter to realize the separation of flocs and large particles from sewage, effectively providing convenience for the later cleaning of flocs and large particles.

[0004] When the above device is used, the flocculant needs to be manually put into the collecting cylinder from the feeding port, which is inconvenient to add the flocculant, and it is inconvenient to control the amount of the flocculant added when adding the flocculant manually.
