Description

Technical Field

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

[0002] Wastewater treatment: The process of purifying sewage to ensure that it meets the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] For example, a sedimentation tank device for sewage treatment with authorization announcement number "CN220714916U" can automatically discharge impurities at the bottom of the sedimentation tank to the outside of the sedimentation tank body when in use, by means of the first auger piece and the second auger piece, without the need for manual impurity removal, thus achieving the purpose of automatic impurity removal. However, when the sewage treatment sedimentation tank device is mixing sewage and flocculant, it uses the stirring below to mix them. Since the stirring position of the equipment is connected to the discharge position, the sewage will flow out directly during stirring, reducing the quality of sewage sedimentation. At the same time, when the sewage treatment sedimentation tank device is discharging sediment and impurities, the sediment and impurities have a certain viscosity and will stick to the discharge pipe, causing the equipment to be blocked, affecting the subsequent equipment discharge work.
