Description

Technical Field

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

[0002] In today's society, wastewater treatment is an unavoidable issue. During the sewage treatment process, flocculants are added to treat the wastewater. Flocculation devices are typically used to treat suspended solids and turbid matter in water. The addition of flocculants aggregates these tiny particles into larger ones, facilitating subsequent sedimentation or filtration. Flocculation devices can be used in water treatment, sewage treatment, and industrial production, helping to improve water quality and wastewater treatment efficiency.

[0003] When treating sewage, the existing device evenly puts the flocculant material into the sewage. The diffusion range of the flocculant is small, and a long time is required to react to achieve sewage flocculation. Therefore, when treating sewage, it is necessary to automatically stir the device after adding the flocculant to effectively condense the impurities and fine particles in the sewage to form treatable flocs, thereby achieving further purification of the sewage. Utility Model Content
