Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a solid-liquid separation treatment mechanism. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people.

[0003] The separation of solids and liquids in sewage is a preliminary step in the sewage treatment process. Generally, preliminary separation of solids and liquids is carried out through sewage sedimentation. Although the preliminary treatment and separation can be completed, the separated solids often still contain extremely rich moisture, making it difficult to perform secondary treatment on the solid sludge. Conventional centrifugal separators, due to the design of their volume and internal structure, can only perform centrifugal separation on the solid-liquid in sewage, and the separation efficiency is low. The sedimented sludge is difficult to be centrifugally treated due to its own weight, so it is difficult to completely remove or fully separate the moisture inside the sludge. Summary of the Utility Model
