Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to sewage solid separation equipment. Background Art

[0002] Wastewater treatment refers to the process of purifying and filtering wastewater to meet the national standards for wastewater discharge. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. Since wastewater generally contains non-degradable solid components, these solid components are often accompanied by a large amount of sewage. If they are discharged directly, it will cause environmental pollution. Therefore, a very important step in wastewater treatment is solid-liquid separation, which separates the non-degradable solids in the sewage and dehydrates these solids.

[0003] Traditional sewage treatment equipment generally relies on the screen to filter and separate solid matter from sewage under the action of gravity. However, the solid impurities after filtration still contain water, resulting in insufficient dehydration of the solid matter, and the residual water in the solid matter will still pollute the environment. There is also a centrifugal dehydration treatment method similar to the drum of a washing machine after filtration, but this dehydration method requires a long centrifugal dehydration time. If the time is insufficient, the dehydration treatment will also be insufficient. At the same time, the energy consumption required for centrifugal dehydration is large, and it is not easy to control the dehydration process, and the dehydration efficiency of solid matter is low. Utility Model Content
