Description

Scum treatment pool for small sewage treatment station

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to a scum treatment tank for a small sewage treatment station.

Background

Skimming scum in the production process of a sewage treatment plant has high water content and needs to be transported outwards after dehydration. At present, two common dehydration modes are mechanical dehydration and filtration. Mechanical dewatering is generally used for large and medium-sized sewage plants, skimmed scum mixed sewage is collected into a sewage tank, and is lifted to mechanical devices such as an integrated scum separator for dewatering by a pump. The filtering is generally used for a small sewage treatment station, a sewage well is arranged at a scum generating point, a scum basket is arranged in the well, the generated scum mixed sewage is directly discharged into the basket, the scum is intercepted in the basket, and the filtered sewage is discharged into a factory inspection well.
