Description

Integrated purification type rainwater flower bed system

Technical Field

The utility model relates to a rainwater processing technology field, concretely relates to integrated form purification type rainwater flower bed system.

Background

The sponge city is a new generation of city rainfall flood management concept, and refers to a city which can be like a sponge and has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and the city can also be called as a water elasticity city. The urban rainwater collection system is particularly characterized in that the urban rainwater collection system can be like a sponge, has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters and the like, has an international general term of low-influence rainwater system construction, absorbs water, stores water, seeps water and purifies water in rainy days, releases and utilizes the stored water as required, and realizes free migration of rainwater in the urban rainwater collection system.

With the universalization promotion of sponge cities, most of rainwater on building roofs can be discharged into peripheral green lands through the disconnected connection of the vertical pipes for regulation and storage. However, the problem of limited storage and regulation facilities in some new or modified projects still exists, and specifically, in the actual construction process, some construction projects, such as industrial plants, have the problems that no greening is arranged around the building, the greening area of the site is small or the area is scattered, no bioretention facilities are arranged, or the roof of the building is a sloping roof or the load cannot meet the requirements of roof greening, and the rainwater on the roof of the building is directly drained into a ground building drainage ditch or directly drained into a rainwater inspection well through a rainwater stand pipe. And the rainwater of draining into building scattered ditch or rainwater inspection shaft has synthesized the pipe network system through place rainwater and has directly drained into the municipal pipe network, and the unable regulation of rainwater has increased the pressure of municipal pipe network, simultaneously because the unable follow source of building roofing rainwater is administered, leads to unable sponge city construction requirement of satisfying. In heavy rain, if a large amount of rainwater is directly drained into an inspection well without regulation and storage, the urban drainage is very easy to be unsmooth, so that waterlogging occurs, and the daily life of people can be directly influenced.

Therefore, there is a need for a system that can effectively treat rain on building roofs in the absence of greenery.
