Low-influence region rainwater treatment and utilization system and region rainwater treatment method

Abstract

The invention discloses a low-influence region rainwater treatment and utilization system and a region rainwater treatment method. The system comprises a retention type gutter inlet, wherein the retention type gutter inlet is separately connected with a rainwater impounding reservoir and a rainwater storage tank respectively through pipes, the rainwater storage tank is used for collecting water or rainwater abandoned from the retention type gutter inlet and overflowed from region greenbelts or grass planting swales, a filtering device is arranged in the rainwater impounding reservoir, and the rainwater impounding reservoir is connected with a drip irrigation system. The low-influence region rainwater treatment and utilization system further comprises a garage top plate drainage ditch, wherein the garage top plate drainage ditch is connected with a rainwater filtering well, and the rainwater filtering well is connected with the rainwater impounding reservoir. The system further comprises multiple underground permeation piles. The system promotes rainwater permeation towards the underground and improves the water permeation speed through the arranged permeation piles, is high in automation level, measures the water amount in the rainwater impounding reservoir through a water level gauge, automatically performs switching when the rainwater amount is insufficient, adopts reclaimed water for water supply, reduces the damage of earlier-stage project construction to formation bearing and decreases the sinking situation of the earth's surface caused by rainfall.

Description

technical field [0001] The invention relates to rainwater collection and utilization, in particular to a regional low-impact rainwater treatment and utilization system and a regional rainwater treatment method. Background technique [0002] The regional low-impact development rainwater system refers to the use of source and decentralized measures to maintain the hydrological characteristics of the site before and after the development of the building area. It has good "elasticity" in disasters and other aspects. When it rains, it absorbs, stores, infiltrates, and purifies water. When needed, it "releases" the stored water and makes use of it. [0003] The design of rainwater for low-impact development in building areas should fully consider the control and utilization of rainwater, and design sponge facilities that can absorb runoff rainwater from roofs, roads, squares, and parking lots in the area, and integrate with urban rainwater pipes and drainage systems and urban rain...

AI Technical Summary

Problems solved by technology

The current research on the regional low-impact rainwater development system involves rainwater regulation and storage, but the rainwater regulation and storage system and the rainwater recycling system are relatively independent, and the link between them has not been clarified

And the rainwater in the storage tank is discharged to the municipal rainwater pipe network, which will waste a lot of rainwater resources

[0008] At present, the way to remove the accumulated water on the roof of the garage is to discharge the drainage directly into the municipal rainwater pipe network or discharge it into the municipal rainwater pipe network after infiltration through the infiltration pond. This part of the drainage cannot be recycled in the area.
