Description

Technical Field

[0001] The utility model relates to the field of ecological environment protection, in particular to a rainwater ecological purification device. Background Technique

[0002] At present, during the flow of rainwater, it often contains a large amount of pollutants such as sediment and garbage; if the pollutants in the rainwater are directly discharged into the water body, it will cause serious damage to the water ecosystem, resulting in the death of aquatic organisms and the imbalance of the ecological balance.

[0003] Rainwater ecological purification is a process of purifying rainwater by using natural ecological systems and artificial ecological engineering. Natural ecology mainly includes ecological systems such as natural vegetation, soil, and wetlands, and artificial treatment mainly includes treatment methods such as rain gardens, ecological retention ponds, and artificial wetlands.
