Description

Technical Field

[0001] The utility model relates to the technical field of sewage pools, in particular to a sewage pool with a filtering structure. Background Art

[0002] The sewage pool is a sewage pretreatment structure, and its main purpose is to intercept impurities in sewage. By adding flocculants into the sewage, the impurities in the sewage are precipitated by the flocculants. The supernatant in the sewage pool is discharged from the drain pipe, and the sediment at the bottom of the sewage pool is pumped out by the sludge pump. In this way, the sewage pool can be used to complete the filtration operation before sewage treatment.

[0003] At present, the filtration structure of the sewage pool with a small box structure mainly covers the entire water inlet of the pool body with a filter net. When the sewage passes through the filter net, the impurities are intercepted by the filter net, and then the filter net is cleaned regularly. However, in order to ensure the normal flow of sewage and avoid the blockage of the filter net causing the sewage to not flow and overflow from the sewage pool, the opening of the pool body will be designed to be large, resulting in a large cross-sectional area of ​​the filter net. Secondly, the filter net will be recessed in the pool body, so that the filter net is at a certain distance from the opening of the pool body, so that more impurities can be accommodated through the filter net, and it is not easy to overflow sewage. However, the main defect of this structural design is that it is inconvenient to clean. The surface area of ​​the filter net is large, resulting in a long single cleaning time. Secondly, the position of the filter net inside the pool body is a certain distance away from the outlet, making it difficult to complete the cleaning operation. To this end, we propose a sewage pool with a filtration structure. Utility Model Content

[0007] By adopting the above technical solution, a series of filtering mechanisms are used to filter the debris in the sewage in sequence, so as to avoid large and small debris from piling up and being difficult to clean.
