Description

Technical Field

[0001] The present invention relates to the technical field of rainwater treatment in sponge cities, and in particular to a rainwater treatment system for a sponge city building. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and respond to natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". The city can adapt to environmental changes and respond to natural disasters like a sponge. The internationally common term is "low-impact development rainwater system construction". When it rains, it absorbs water, stores water, infiltrates water, and purifies water. When needed, the stored water is released and used to achieve the free migration of rainwater in the city. Starting from the ecosystem service, the construction of water ecological infrastructure across scales and combining a variety of specific technologies to build water ecological infrastructure are the core of the sponge city.

[0003] In the prior art, the patent with announcement number: CN115075085A discloses a road rainwater treatment system for sponge city construction, including a base soil layer, a protective concrete layer, a trapezoidal groove, permeable soil, washed sand, washed gravel, a first pipe, a drainage component and a filtering component. The protective concrete layer is cast on the top middle outer wall of the base soil layer, a trapezoidal groove is opened on the top outer wall of the protective concrete layer, washed gravel is laid on the bottom inner wall of the trapezoidal groove, washed sand is laid on the top outer wall of the washed gravel, permeable soil is laid on the top outer wall of the washed sand, and a first pipe is arranged on the bottom outer wall of the trapezoidal groove; the present invention has a better treatment effect on rainwater, and is provided with washed sand and washed gravel for preliminary filtration, and the provided filtering component is convenient for secondary filtration and purification of rainwater, thereby improving the safety of rainwater utilization, and the provided drainage component can automatically open the sealing cover according to the water volume, so as to facilitate the timely discharge of rainwater and prevent waterlogging.

[0004] Although the technical solution proposed by the above patent technology can filter and purify rainwater and prevent waterlogging, the rainwater treatment system proposed by the above patent technology lacks a system for monitoring rainwater, which makes it impossible to reasonably utilize rainwater and form a scientific and convincing database, thereby making it impossible to scientifically manage the urban water environment, control and plan pollution sources. In view of this, the present application proposes a sponge city building sponge city rainwater treatment system. Summary of the invention
