Description

Multifunctional rainwater collecting device for residential area

Technical Field

The utility model belongs to the technical field of the rainwater is collected, especially, relate to a district is with multi-functional rainwater collection device.

Background

Rainwater in the existing community is generally not collected but directly discharged to a sewage treatment plant through a sewage pipeline, which causes the cost of the sewage treatment plant to be increased; or discharged into a river or lake through a special rainwater pipe. The greening water of the existing residential area is recycled by using reclaimed water or directly using tap water, so that the cost is higher and the rainwater is not fully utilized. The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be also called as a water elasticity city. The international generic term is "low impact development storm water system construction". When raining, the utility model absorbs water, stores water, seeps water and purifies water, and when needed, the stored water is released and utilized.

In summary, the problems of the prior art are as follows:

(1) rainwater in a community is generally directly discharged through a sewage pipeline or a special rainwater pipeline, the cost of pipeline laying is high, and water resources are wasted.

(2) Some greening water of the existing residential area is recycled by using reclaimed water or directly using tap water, so that the cost of the water is higher, and rainwater is not fully utilized.
