Embodiment Construction

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0021] A sponge city rainwater collection and reuse system in a building area provided by the present invention includes a source treatment system, a process transmission system and a terminal collection and reuse system.

[0022] The source treatment system consists of ecological low-impact development facilities such as ecological detention ponds, sunken green spaces, and ecological grass-planting ditch, filter systems such as building drainage pipe filters, and suspended rainwater well filters. The main function is source collection pretreatment Rainwater intercepts pollutants in the initial rainwater runoff of green spaces, roofs and roads. At the same time, ecological facilities can reduce the total amount of ru...

Abstract

The invention relates to a sponge city rainwater collection reuse system of a residential area. The sponge city rainwater collection reuse system comprises a source processing system, a process transmission system and an end collection reuse system. The source processing system is used for collecting partial rainwater within a designed rainfall, retaining pollutant in rainwater runoff on green areas, roofs and roads in the residential area, simultaneously reducing the total runoff volume, and complementing underground water. The process transmission system enables another part of rainwater within the designed rainfall to enter residential area pipe network through ecological facilities, overflow ports of the pavement and overflow pipes, and to enter the end collection reuse system. The end collection reuse system is used for lifting and reusing the processed rainwater, the rainwater exceeding the designed rainfall is overflowed to a downstream municipal pipe network through a shunting system. The rainwater collection reuse system is low in cost and has high environmental benefits and ecological benefits, the source is controlled and the process is optimized, a series of collection reuse sponge city low impact development rainwater utilization system technologies are provided, and the purposes of waterlogging prevention, decontamination and rainwater resource re-utilization are achieved.

Description

technical field [0001] The invention relates to a rainwater collection and reuse system, in particular to a rainwater collection and reuse system and a treatment method for a sponge city in a building area. Background technique [0002] With the rapid growth of population and rapid economic development, water shortage and pollution have become problems faced by the whole world. The acceleration of urbanization has led to an increase in the paved area of ​​hard pavements and building density in cities, resulting in an increase in surface rainwater runoff, a decrease in infiltration, frequent flooding, and aggravated damage. The initial runoff rainwater contains a lot of impurities and is directly discharged into the water body, causing serious water pollution. [0003] The treated rainwater can not only be used for urban greening and road spraying, but also infiltrate and recharge underground to supplement groundwater, control rainwater runoff pollution, improve the urban ec...
