Technical Field

The invention relates to the technical field of rainwater circulation collection, in particular to an ecological rainwater circulation collection system.

Background

Rainwater is a precious natural fresh water resource, however, rainwater in the prior art is not reasonably utilized. In recent years, with the rapid development of Chinese urbanization, the urban heat island effect is prominent, and a lot of negative effects are brought to the life of people. With the emphasis of people on ecological environment, the construction of sponge cities appears, the sponge cities are a new generation of urban rainfall flood management concept, and refer to cities which have good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can also be called as water elasticity cities. The sponge city can absorb, store, seep water and purify water when raining, and release and utilize the stored water when needed. The rainwater storage, infiltration and purification in urban areas are realized to the maximum extent on the premise of ensuring the safety of urban drainage and waterlogging prevention, and the utilization of rainwater resources and the ecological environment protection are promoted. The systematicness of natural rainfall, surface water and underground water is planned, water recycling links such as water supply and drainage are coordinated, and the complexity and the long-term property are considered.
