Online handling storage pond, emergency flood discharge gallery and drainage pump station combined system

Abstract

The invention discloses an online handling storage pond, emergency flood discharge gallery and drainage pump station combined system. The combined system comprises an online handling storage pond and an emergency flood discharge gallery which are communicated with a city drainage pipeline; the combined system is characterized by further comprising a water collection pond and a drainage pond; the water outlet end of the online handling storage pond is communicated with the water collection pond; the drainage pond and the water collection pond are communicated through a downward-open weir gate; a drainage pump is arranged in the water collection pond; the drainage pump is communicated with the drainage pond through a drainage pipeline. The online handling storage pond, emergency flood discharge gallery and drainage pump station combined system is simple in structure and convenient to use; the height of the downward-open weir gate can be adjusted according to the rainfall condition, whether the drainage pump needs to be started or not can be judged according to the outlet receiving water level, and thus both safety and energy conservation are achieved.

Description

Technical field [0001] The invention relates to an initial rainwater treatment combined system, which belongs to the technical field of rainwater treatment, and particularly relates to an online treatment storage tank used when the outlet water elevation of the storage tank is lower than the design flood level of the receiving water body. The combined system of emergency flood corridor and drainage pumping station. Background technique [0002] In the prior art, various pipelines for the initial rainwater discharge in cities usually use online treatment storage tanks to filter and purify the initial rainwater, and the rainwater filtered and purified by the online treatment storage tanks will be directly discharged into natural water bodies. The structure of the treatment storage tank is as follows figure 1 As shown, although this method has the advantage of low energy consumption, the online treatment storage tank is generally built on a lower terrain. When heavy rainfall or othe...

[0002] In the prior art, the online treatment and storage tanks are used to filter and purify the initial rainwater in various pipelines that usually discharge the initial rainwater in cities, and the rainwater filtered and purified by the online treatment and storage tanks will be directly discharged to natural water bodies. The structure that handles the storage pool is as follows figure 1 As shown, although this method has the advantage of low energy consumption, the on-line processing and storage tanks are generally built in low-lying places. When the elevation is high, the rainwater in the online processing storage tank cannot be discharged smoothly, resulting in the stagnation of rainwater in the overall urban rainwater pipeline, thus causing waterlogging
