Problems solved by technology

[0003] At present, the existing natural precipitation is 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, and if it encounters water accumulation in low-lying places, it will cause Floods; secondly, rainwater becomes sewage after being discharged into the sewer pipes, which not only increases the processing workload of the sewage treatment plant, but also causes a waste of water resources

Embodiment 1

[0019] A rainwater recycling system in a sponge city residential area, including a rainwater collection and treatment system, a rainwater delivery system and a pre-hanging green plant wall panel; wherein the rainwater collection and treatment system consists of a pump 3, a roof water storage tank 1, a drain valve 2, a filter The device 7 is composed. The water pump is connected to the roof water storage tank 1 through pipelines, the top of the roof water storage tank 1 is connected to a pipeline, and the outside is connected to the rainwater delivery system by a drain valve 2 . The rainwater conveying system is a wall-mounted water pipe, including a first drainage channel 5 and a second drainage channel 4, wherein the first drainage channel 5 communicates with the drain valve 2 and the pre-hanging green plant wallboard 6, and the second drainage channel 4 leads to downstairs. The rainwater collection and storage system uses the drainage channel of the roof itself and then is ...

Embodiment 2

[0021] A rainwater recycling system for a residential area in a sponge city adopts the same structure as that of Embodiment 1, wherein the first drainage channel 5 has two water delivery pipes that communicate with a single green plant wall panel 6 at the same time.

Embodiment 3

[0023] A rainwater recycling system for a residential area in a sponge city adopts the same structure as that of Embodiment 1, wherein small holes are evenly distributed on the first drainage channel 5 to facilitate rainwater spraying.

Abstract

The invention discloses a sponge city residential area rainwater recycling system which comprises a rainwater collection treatment system, a rainwater conveying system and a pre-hung green plant wallboard. The rainwater collection treatment system filters rainwater and then stores the rainwater in a water storage tank at a roof in a centralized manner by the aid of a drainage channel of the roof and the action of a water pump, and the rainwater conveying system conveys the rainwater for irrigation to the pre-hung green plant wallboard through a first drainage channel when required. When the water quantity of the water storage tank of the roof exceeds maximum water storage quantity, the rainwater can be drained to a downstairs header tank through a second drainage channel and used for otherapplications. By the aid of a pre-built sponge city application system based on a wall, the rainwater is collected, filtered, stored and then conveyed to the wall to serve as irrigation water for pre-hung green plants. When the water quantity is sufficient, the collected rainwater can be conveyed to a first floor to serve as the irrigation water, water resources are saved, and the pressure of a municipal sewer system is relieved. The sponge city residential area rainwater recycling system can be used for a newly built house or renovation of existing houses.

Description

technical field [0001] The invention belongs to the technical field of urban rainwater treatment, in particular to a rainwater recycling system for a sponge city 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. When it rains, it absorbs water, stores water, and releases the stored water when needed. 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 circulation 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 link...
