Storage seepage purification drainage type rainwater recycling device for roadside

Abstract

The invention discloses a storage seepage purification drainage type rainwater recycling device for the roadside. The device includes a rainwater garden system, a reservoir system and an inspection manhole. The rainwater recycling system is arranged in a green belt outside a curb, an opening is formed in the curb, a surface runoff can be drained from the opening to the interior of the rainwater recycling system, stored in a reservoir A after purified in the rainwater garden system, and stored in a reservoir B through an overflowing device after the reservoir A reaches full storage, so that the problem that surface gathered water cannot be discharged is solved, and the pollution of the surface runoff is effectively treated. When the rainfall intensity is too large, a surface runoff with a high pollution degree at the initial stage can still be effectively treated, and the device has the advantages of rapid drainage of gathered water and interception of rainwater to the utmost extent while treating the surface runoff; through the plane layout, the effects of flood peak time delaying and flood peak flow reducing can be achieved to a certain degree, and the present situation of seeing the sea in a city is helped to be relieved.

Description

technical field [0001] The patent of the invention belongs to the technical fields of municipal engineering and environmental engineering, and in particular relates to a rainwater reuse device for roadside storage and drainage. Background technique [0002] Rainwater is an important part of the water cycle system, which plays a huge role in regulating and supplementing regional water resources and improving the ecological environment. However, due to the acceleration of the urbanization process, the surface hardening of the city is getting higher and higher, destroying the original water circulation system, especially some more developed cities with more rain are facing increasingly serious rainwater problems, urban non-point source pollution caused by rainstorm runoff It has drawn great attention from the international community. Rain gardens emerged as a municipal landscape technique for dealing with pavement runoff. [0003] At present, the road drainage in the city is ...

AI Technical Summary

Problems solved by technology

[0003] At present, the road drainage in the city is realized by the drainage wells and ditches set up on the road, but they cannot deal with the increasingly polluted road runoff, which carries a large amount of pollutants (suspended particles, nutrient salts, etc.) , heavy metals and polycyclic aromatic hydrocarbons (PAHs, etc.) migrate into the water body through the urban drainage pipe network, causing obvious pollution to the water quality of the receiving water body, and causing considerable harm to the water environment; in addition, due to the increasing degree of urban surface hardening With the intensification of extreme weather, many cities are facing both the problem of water shortage and the embarrassment of "the city looks at the sea". Therefore, the combination of recycling rainwater and rational drainage of rainwater has attracted much attention.

[0004] At the same time, domestic and foreign studies have been carried out on the model analysis of urban road surface runoff pollution and the structure and filling scheme of rain gardens to deal with pollutants, but there is no setting that integrates the two, and domestic and foreign research on rain gardens Most of them stay in large-scale urban landscape facilities and do not link them with the treatment of urban road surface runoff. Currently, there are no reasonable road ancillary facilities to purify heavily polluted road surface runoff, rainwater cannot be effectively used, and rainstorm runoff cannot be realized. control
