Description

Rainwater collection and purification device for sponge city

Technical Field

The utility model relates to the technical field of rainwater purification devices, in particular to a rainwater collection and purification device for a sponge city.

Background

The sponge city is a new generation city rain and flood management concept, and refers to that the city has good stability and elasticity in the aspects of adapting to environmental changes, natural disasters caused by rainwater and the like, and the international general term is the construction of a low-influence development rainwater system, wherein interception and utilization of the initial rainwater and later rainwater infiltration are important parts in the construction of the sponge city, and the rainwater is controlled, so that the natural accumulation, natural infiltration and natural purification are placed, and the ecological and conservation water resources of the city are restored.

In the rainwater collecting and purifying treatment process, besides filtering impurities in water, flocculating drugs are added into the water to precipitate fine impurities or harmful substances in the rainwater, but the rainwater collecting and purifying process is dynamically carried out, the dosage is not easy to control, the dosage is less, the flocculating effect is poor, and the dosage is more, so that waste is caused.
