Technical Field

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

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. At present, the conventional process of sewage treatment will first remove solid debris in the sewage, that is, use a sewage treatment tank with a water filtration structure.

[0003] At present, sewage treatment tanks for solid-liquid separation generally have a horizontal filter structure arranged in the inner cavity to filter out some debris. Larger debris cannot pass through the filter and accumulate. The mesh of the filter is accumulated over a large area, which will cause blockage and affect the efficiency of sewage passing through. In addition, the filtered debris needs to be manually removed from the sewage treatment tank. Some debris has a high water content due to its water-absorbing nature. Directly removing the debris will make the water filtration work incomplete.

[0004] Therefore, a sewage solid-liquid separation treatment device is needed to solve the problem in the prior art that the mesh of the filter screen is clogged due to large-scale accumulation and affects the sewage passing efficiency, and the high water content of the debris leads to poor sewage separation effect.
