Embodiment Construction

[0038] The following is attached Figure 1-5 The application is described in further detail.

[0039] A sponge city rainwater collection and purification comprehensive system, refer to figure 1, including pavement water collection mechanism, green belt base water mechanism, water storage mechanism 5, purification mechanism and water collection tank 8. The rainwater from the road surface water collection mechanism is filtered by the green belt water filter mechanism 4, and then joins with the rainwater collected by the green belt water filter mechanism 4 into the water storage mechanism 5. After the rainwater in the water storage mechanism 5 is purified by the purification system, it is collected in the water collection tank 8 for urban greening water, road water, fire water, etc.

[0040] The pavement water collection mechanism includes the road base 1 and the water collecting chamber 11. The surface of the road base 1 is provided with a drainage ditch 15. The bottom of the ...

Abstract

The invention relates to a sponge city rainwater collecting and purifying integrated system which comprises a road surface water collecting mechanism, a green belt water filtering mechanism, a water storage mechanism, a water purifying mechanism and a water collecting tank which are sequentially arranged in the flowing direction of rainwater. The purifying mechanism comprises a purifying box. A sand accumulation chamber, a coagulation chamber, an ultraviolet sterilization oxidation chamber and an adsorption chamber are sequentially arranged in the purification box in the rainwater flowing direction, a first partition plate is arranged between the sand accumulation chamber and the coagulation chamber and provided with an overflow port, the overflow port is provided with a flocculating agentadding device, and the portion, located on the side wall of the adsorption chamber, of the purification box communicates with a drainage pipe. One end of the drainage pipe away from the purifying boxis connected with the water collecting tank. Impurities in collected rainwater can be reduced, and the utilization range of recycled rainwater is widened.

Description

technical field [0001] The invention relates to the field of urban water resource utilization, in particular to a sponge city rainwater collection and purification comprehensive system. Background technique [0002] There are uneven water resources and water shortages in the northern and southern regions of China. With the promotion and development of urban construction, the area of ​​green land has been reduced, and natural landforms such as green land and wetlands that originally had the function of water conservation have evolved into hard urban areas. On the ground, waterlogging disasters occur during heavy rainfall, and the loss of water resources after heavy rains leads to dryness and water shortage. The phenomenon of "every rain will be flooded, and rain will be drought" will destroy the balance of water storage and drainage in the city. [0003] Sponge city can adapt to environmental changes and deal with natural disasters with good flexibility, and follows the regul...
