Embodiment Construction

[0023] This embodiment is specifically designed and constructed based on the content of the present invention, but the application scope of the present invention is not limited to this embodiment.

[0024] figure 1 The flow chart of the method for low-carbon stagnation of rainwater at the source, including reducing the flow of water by controlling the rainwater that seeps into the underlying surface; reducing the flow of water by using low-lying ecological plant retention ponds, and solving the problem of rainwater during extreme heavy rains by using surface water bodies. Store and solve the rainwater recharge in the dry season.

[0025] The present invention can specifically adopt figure 2 The project layout shown, the total catchment area of ​​the source precipitation is 120,000 m 2 , The permeable surface of the underlying surface is mainly green space 3, with an area of ​​50,000 m 2 According to the topography, the roof rainwater and road rainwater generated in the catchmen...

Abstract

The invention discloses a low-carbon sluggishing method for source rainwater. In the method, the runoff yield is reduced, namely rainwater penetrates into an underlying surface as possible after falling onto the underlying surface so as to reduce the generated rainfall runoff; the conflux is reduced, namely the conflux runoff passes through a low-lying ecological plant interception basin after the rain forms the runoff so as to extend the runoff way, improve the infiltration capacity of the rainwater, improve the reduction of rainwater runoff pollution load and prolong the rainwater collection time on the ground; rainwater of extraordinary rainstorm is stored, namely the rainwater runoff is guided into a ground water body after the rainwater is converged so as to store the rainwater by using the water level floatation space of the ground water body and reduce the external flux of the rainwater; and the rainwater in summer is recharged, namely the rainwater stored in the ground water body is charged back to the low-lying ecological plant interception basin by a water pump when the rain does not fall in dry seasons so as to promote the stored rainwater to infiltrate in dry seasons. The system has the advantages of low-cost investment and operation of rainwater collection and treatment, emission reduction of greenhouse gas, the reduction of rainwater runoff pollution load and the like.

Description

Technical field [0001] The invention belongs to the technical fields of water supply and drainage and environmental protection, and specifically relates to source rainwater collection and recharge, and greenhouse gas emission reduction in water systems. Background technique [0002] The existing urban rainwater system is to collect rainwater as soon as possible after the source rains to the underlying surface, and then discharge it into the municipal rainwater pipe network to discharge the town to ensure urban safety. [0003] In this traditional urban rainwater collection, transportation and discharge system, rainwater needs to be transported over long distances. In this process, a large amount of rainwater will be generated to increase energy consumption, daily operation and maintenance of municipal drainage network and other resources and energy consumption. Therefore, the traditional urban sewage treatment and rainwater collection and treatment system is an operating mode with ...
