Residential district sponge urban facility system

Abstract

The invention discloses a residential district sponge urban facility system comprising an ecological grass planting ditch, a sunken lawn, a rainwater garden, a rainfall pipe and a storage tank, wherein the ecological grass planting ditch is communicated with the rainwater garden through a first drain pipe, the sunken lawn is communicated with the rainwater garden through a second drain pipe, the rainwater garden is communicated with the storage tank through a third drain pipe, the rainfall pipe is located on an outer side wall of a building, an upper end of the rainfall pipe is communicated with the roof of the building, and a lower end of the rainfall pipe is communicated with the ecological grass planting ditch or the sunken lawn. The residential district sponge urban facility system disclosed by the invention can guide rainwater on the roof and on the ground of a residential district into the sponge urban facility system of the residential district for absorption, purification and collection, thereby not only alleviating the pressure of the drainage system of the residential district and the municipal pipe, but also saving water resources, and the collected water body can be directly applied to road and greening spray, etc.

Description

technical field [0001] The invention belongs to the technical field of urban rainwater treatment, in particular to a sponge city facility system in a residential area. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, and its complexity and long-term nature s...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing natural precipitation and surface water are generally discharged into the sewer pipes, but this treatment method has some disadvantages: First, the discharge of a large amount of rainwater into the sewer pipes will increase the overall drainage pressure of the city. Water will cause floods; second, rainwater will become sewage after being discharged into the sewer, which not only increases the processing workload of the sewage treatment plant, but also causes waste of water resources; third, when the surface rainwater is discharged into the sewer, the garbage along the road will be When it rains, the chemical fertilizers and pesticides contained in the green belts around the road will enter the drainage pipes with the rainwater, endangering the ecological environment
