Embodiment Construction

[0034] Such as Figure 1 to Figure 10 As shown, the flood regulation and storage rainwater reuse system in the sponge city includes the rainwater reuse system and the flood regulation and storage system. The function of flood discharge and drainage.

[0035] The rainwater reuse system includes a rainwater collection frame 1 and a rainwater reuse pool 12. The rainwater collection frame 1 is installed on a building in the sponge city; the rainwater collection frame 1 includes a surrounding rainwater frame 2 and a rainwater conduit 3, and the surrounding rainwater frame 2 is fixed. On the outside of the building, around the building, its shape is designed according to the shape of the building, and it is poured on the building with the help of reinforced concrete. The surrounding rain rack 2 is arranged horizontally, and there are several sets from top to bottom. The upper end of the surrounding rain rack 2 is open, and the opening of the surrounding rain rack 2 is provided with...

Abstract

The invention discloses a flood water regulation and storage-rainwater reuse system in a sponge city. The flood water regulation and storage-rainwater reuse system in the sponge city comprises a rainwater reuse system and a flood water regulation and storage system. Aiming at the insufficiency of the prior art, a set of comprehensive rainwater processing system which is capable of regulating and storing flood water and reusing the rainwater at the same time is designed. The flood water storage system can be started in a proper time according to the amount of rainfall, the flood relief effect is obvious, and the problems that the city is bound to suffer waterlogging when it rains and the interval between drought and flood is very short are solved. The rainwater reuse system is combined with buildings of the sponge city, devices for collecting the rainwater are built on the buildings, after a simple purification process, the rainwater can have various functions, such as toilet flushing, floor moping, afforestation, artificial fountains, industrial water and the like, thus the reasonable utilization of rainwater resources is achieved, and the municipal water using stress is relieved.

Description

technical field [0001] The invention relates to a rainwater treatment system, in particular to a rainwater reuse system for flood regulation and storage in a sponge city. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water when needed. and take advantage of it. Improve the functions of urban ecosystems and reduce the occurrence of urban flood disasters. [0003] To build a sponge city, we must first reverse the concept. The traditional urban construction model is full of hardened roads. Whenever there is heavy rain, drainage is mainly relied on "grey" facilities such as pipes, canals, and pumping stations. The main planning and design concepts are "quick drainage" and "end-centralized" control, which often results in waterlogging every rain, a...
