Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage filtration in sponge cities, and in particular to a comprehensive rainwater and sewage filtration belt structure in sponge cities. Background Art

[0002] With the acceleration of urbanization, the management of urban stormwater and sewage has become a critical issue for sustainable urban development. Traditional stormwater drainage systems often fail to effectively handle the mixing of rainwater and sewage, leading to water pollution, urban flooding, and ecological degradation. To address this issue, the sponge city concept emerged, emphasizing the integration of natural hydrological cycles into urban infrastructure to enhance cities' ability to utilize and manage stormwater.

[0003] The core of the sponge city concept is to capture, store, purify, and reuse rainwater through green infrastructure and intelligent water treatment technologies. This concept focuses not only on water treatment but also on the protection and restoration of ecosystems. By constructing natural filtration devices such as rain gardens, permeable pavement, and wetland systems, sponge cities effectively absorb rainwater during rainfall, reducing surface runoff, thereby alleviating urban waterlogging and reducing pressure on sewage treatment.

[0004] However, despite the growing acceptance of the sponge city concept, existing technologies still have some shortcomings in practical application. For example, traditional sedimentation and filtration facilities often face problems such as insufficient capacity, low sedimentation efficiency, and difficult maintenance when treating rainwater and sewage. Therefore, the development of more efficient and flexible rainwater and sewage treatment equipment is imperative.

[0005] Therefore, it is very necessary to invent a sponge city rainwater and sewage comprehensive filter belt structure. Utility Model Content
