A rainwater collection, purification and recycling structure on the roof of an environmentally friendly building

Abstract

The invention discloses a rainwater collection, purification and recycling structure on the roof of an environmentally friendly building in the technical field of rainwater collection, purification and recycling on the roof of an environmentally friendly building, including an environmentally friendly building, a rainwater filtering mechanism and a graded storage mechanism. The rainwater filtering mechanism is set in Around the environment-friendly building, the graded storage mechanism is arranged under the rainwater collection and filtration mechanism; the present invention collects and filters the rainwater on the roof of the environmental protection building through the rainwater filtration mechanism, and uses the graded storage mechanism to collect the rainwater when the rainfall is large. First, the first water storage tank is used to initially collect rainwater. When the rainfall is large, the rainwater in the first water storage tank is automatically discharged into the second water storage tank, which can effectively prevent the water storage tank from overflowing.

Description

technical field [0001] The invention relates to the field of rainwater collection, purification and recycling on the roof of an environmentally friendly building, in particular to a structure for collecting, purifying and recycling rainwater on the roof of an environmentally friendly building. Background technique [0002] Environmental protection building refers to saving resources (energy saving, land saving, water saving, material saving) to the greatest extent, protecting the environment and reducing pollution during the whole life cycle of the building, providing people with healthy, applicable and efficient use of space, and being in harmony with nature. A harmonious symbiotic building, in order to save water resources, the roof of the environmentally friendly building will collect and utilize rainwater. [0003] However, at present, when the rainwater collection device on the roof of the environmental protection building collects the rainwater from the roof of the env...
