Description

Technical Field

[0001] The present application relates to the field of rainwater treatment, and in particular to a roof initial rainwater separator device combined with a sponge wetland. Background Art

[0002] Currently, factories and residential buildings account for a large proportion of urban areas. On sunny days, rooftops are prone to accumulating large amounts of dust and other impurities due to atmospheric precipitation. On rainy days, rainwater washes away impurities from the rooftops. The amount of impurities carried by rainwater varies with the duration of rainfall. Initially, the pollutant concentration in rainwater is high and the water volume is small, while later, the pollutant concentration in rainwater is low and the water volume is large.

[0003] As many places adopt the concept of sponge cities to treat rainwater containing pollutants, they are limited by the space within the plots and cannot arrange large areas of wetlands or retention areas to treat rainwater. Smaller sponge facilities are only suitable for treating rainwater when the rainfall is small. Once heavy rain occurs, the rainwater cannot be effectively retained in the sponge facilities, and untreated rainwater will bring accumulated pollutants into the river, causing pollution to the river.
