Description

Technical Field

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

[0002] Sewage treatment is a process of treating sewage to make it meet certain discharge standards. In recent years, due to the rapid development of the processing and manufacturing industry and the slow development of the corresponding environmental protection industry and the lack of environmental awareness, my country's surface water and groundwater pollution have become more serious. In some places, water pollution has endangered people's normal lives. Flocculation and sedimentation are one of the most important steps in the sewage treatment process. During the flocculation and sedimentation process, flocculants are added to the sewage to cause the suspended particles in the water to coagulate and precipitate. However, if the flocculant is directly added to the tank, it will cause uneven diffusion of the flocculant in the sewage, and the flocculation and sedimentation effect of the sewage will be poor. When the sewage enters the flocculation tank, the impact force can easily wash away the flocculated sediment at the bottom of the tank. At the same time, it is inconvenient to clean the inner wall of the flocculation tank after use.

[0003] Therefore, it is necessary to design a sewage static flow flocculation sedimentation tank with strong practicality. Utility Model Content
