Clean seepage storage device and operation method for roof rainwater source based on the concept of sponge city

Abstract

The invention discloses a roof rainwater source clean storage and seepage device based on the sponge city concept and a running method, relates to the field of rainwater source emission reduction and water resource protection, and discloses a technology suitable for clean collection of roof rainwater and conservation of underground water. The roof rainwater source clean storage and seepage device comprises a rainwater flow dividing tank, a rainwater flow abandoning tank, a water storage tank, an underground water conservation system and a control system. The control system can receive signals of a water quality sensor and an illumination sensor and send control instructions to an electric three-way valve and a valve of a flow abandoning hole. The roof rainwater source clean storage and seepage device has the functions and the advantages of rainwater separation and flow division, rainwater storage and accumulation and underground water clean conservation, is beneficial for reducing urban runoff pollution load, relieving drainage pressure on a city pipe network and reducing flood disasters and has great significance in improving the urban ecological water environment, relieving urban water resource shortage and promoting the harmonious development between human and nature.

Description

technical field [0001] The invention relates to the fields of rainwater source reduction and water resource protection, in particular to a roof rainwater source cleaning infiltration storage device and an operating method based on the concept of a sponge city. Background technique [0002] Urbanization is a powerful engine to maintain sustainable and healthy economic development. However, with the development of rapid urbanization, most of the green areas, wetlands, ditches and other areas that originally had the function of water conservation have evolved into hardened ground, causing the city to only Can rely on municipal pipe network drainage. At present, the traditional municipal drainage system in the city mainly has the following shortcomings: [0003] (1) In the event of heavy rain, the surface runoff of the city will increase significantly, and the flood discharge capacity of the municipal pipe network is far from sufficient, causing road flooding and waterlogging; ...

AI Technical Summary

Problems solved by technology

[0003] (1) In the event of heavy rain, the surface runoff of the city will increase significantly, and the flood discharge capacity of the municipal pipe network is far from sufficient, causing road flooding and waterlogging;

[0004] (2) Rainwater immersion carries a large amount of domestic garbage and pollutants on the ground, which will block the municipal pipeline, and the water body will be discharged into the natural environment, which will aggravate the pollution of the natural water body;

[0005] (3) A large amount of rainwater is discharged into natural water bodies through the municipal pipe network, which will increase the load on the river system and even cause ecological environment damage;

[0006] (4) Cause a large loss of rainwater resources, which cannot be fully recycled
