[0003] In order to create a better surface water environment, storage tank projects often require the construction of supporting pre-treatment facilities to reduce the degree of pollution of overflow sewage to the receiving water body. Most of the existing storage tanks in cities are buried deep, and the water inlet is mostly in the form of waterfall steps, which requires the internal space of the storage tank. The water in the storage tank is treated by a coarse screen, and there are still a large number of pollutants such as SS in the water. If there is continuous rainfall, the storage tank will be seriously muddy and difficult to dredge. Moreover, the overflow sewage is mostly stored in the same space, and the storage tank cannot be used during maintenance. At the same time, it brings a lot of equipment maintenance and dredging maintenance work to the operating personnel.

[0004] In the actual operation of large-scale sewage trunk lines, in addition to the dry season sewage generated in the transportation area, there is also some intercepted water from the combined system, intercepted sewage in the dry season, initial rainwater in the service area, groundwater, etc., which fluctuate to varying degrees in different weather and at different times. As a result, the water volume transported by the trunk line exceeds the treatment capacity of the terminal sewage treatment plant, resulting in overflows in front of the plant of varying sizes.
