Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, to a prefabricated structure of an assembled sewage pool and a manufacturing method thereof. Background Art

[0002] Sewage treatment is the process of purifying sewage. The goal of sewage treatment is to make sewage meet the water quality requirements for discharge into a water body or reuse. In the construction process of traditional sewage treatment plants, the sewage pools are generally built using traditional construction technology, which not only has a long construction period, but also pollutes the surrounding environment. In the construction process of new sewage treatment plants, assembled sewage pools will be used, which have a short construction period and a more environmentally friendly construction process. The components of assembled sewage pools are produced in prefabrication plants, and the quality is highly controllable.

[0003] A major drawback of existing prefabricated sewage pools is that long-term sewage treatment will lead to the accumulation of more sediment at the bottom of the sewage pool, and the side walls of the sewage pool may produce more green algae, so that the sewage treatment pool needs to be cleaned regularly, and the cleaning cycle is short. For example, in the invention patent with publication number CN110821256A, it discloses a prefabricated sewage plant biochemical pool, which includes an L-shaped component, a transverse baffle and a prefabricated pad. The L-shaped component includes an integrally formed side baffle and a bottom plate. At least two L-shaped components are mirror-imaged and arranged relative to each other and assembled into a U-shaped trough structure, and the bottom plate is attached to the top surface of the prefabricated pad and installed on the prefabricated pad. The two ends of the U-shaped trough structure in the length direction are respectively blocked with transverse baffles.
