Intelligentized roof garden rainwater collecting and utilizing system

Abstract

The invention discloses an intelligentized roof garden rainwater collecting and utilizing system which comprises a planting layer and a plurality of humidity sensors embedded in the planting layer. One side of the planting layer is provided with a grille well, a coarse grille is installed at a water inlet formed in the top of the grille well at 90 degrees, the spacing distance of the coarse grille is 6-10 mm, the area of the grille is larger than 0.6 m<2>, a fine grille is installed in the grille well by being inclined in 60-75 degrees and installed on the side opposite to the flow-in direction of rainwater, the bottom of the grille well is filled with a rainwater purifying rubble layer, and an aeration regulating tank, a hydrolytic acidification tank, a contact oxidation tank, a biological aerated filter, a stored water storage tank and a liquid level regulating tank are sequentially connected on one side of the rainwater purifying rubble layer. According to the intelligentized roof garden rainwater collecting and utilizing system, rainwater collecting, purifying, storing and recycling are achieved, the more appropriate humidity environment can be always kept in the planting layer, the plant growth capacity is improved, and power is supplied through solar energy, so that energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of rainwater recycling, in particular to an intelligent roof garden rainwater collection and utilization system. Background technique [0002] With the development of urbanization, the shortage of urban water resources is becoming more and more serious. However, in daily life, the amount of rainwater accumulated on the roof cannot be underestimated. If this part of rainwater can be collected and reused, resources can be saved to a certain extent. [0003] The research on rainwater utilization in China has a long history, but the development is relatively slow. Some theoretical research and practical exploration have only appeared in the past ten years. However, from the perspective of urban green space, there is no systematic theoretical guidance, and more of it just stays at the level of urban green space. Most of the green space irrigation fails to utilize rainwater resources. [0004] Roof gardens not only have e...

Problems solved by technology

However, the existing roof gardens either focus on practicality, such as planting vegetables to meet the needs of life; or focus on ornamental, such as focusing on flowers and plants, which seriously weakens the environmental function of the roof garden, and fails to integrate the economic value, environmental value and Organic combination of ecological value
