Description

technical field

[0001] The invention relates to the field of rainwater purification and treatment, in particular to a roof rainwater interception and purification system. Background technique

[0002] my country is a country with low per capita water resources. As a staged product of the natural water cycle, rainwater is a precious water resource. With the acceleration of urbanization and the continuous increase of impervious surfaces, the increase of rainwater runoff and serious pollution of downstream water bodies have caused a series of ecological and environmental problems. As an important part of urban impermeable area, roof occupies a considerable urban area. Because the roof occupies the middle of the atmosphere and the ground, the pollutants in the atmosphere and the corrosion of the roof material itself make the roof rainwater runoff have certain pollution characteristics. This will endanger the receiving water body and the urban environment. Compared with the wa...
