Green building rainwater collecting and reusing device

Abstract

The invention discloses a green building rainwater collecting and reusing device, relates to the technical field of rainwater collecting and reusing, and mainly solves the problem that an existing rainwater collecting and reusing device is poor in rainwater storage capacity after rainwater is collected. The device comprises a water collecting pipe, the water collecting pipe is connected with a first filtering box through a connecting cylinder, a filtering cylinder is arranged in the first filtering box, the first filtering box is connected with a second filtering box through a connecting pipe,an arc-shaped filtering plate is arranged in the second filtering box, a circulating pump is arranged at the bottom of the second filtering box, the circulating pump is connected with a circulating pipe, the circulating pipe is connected to the position above the arc-shaped filtering plate, the second filter tank is connected with a water passing chamber of a middle water tank through a first guide pipe, the middle water tank is connected with a water storage tank through a second guide pipe, a first water pump is arranged in the water storage tank, and the first water pump is connected withan oxygenation device. Through the structure, the rainwater storage quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and reuse, in particular to a rainwater collection and reuse device for green buildings. Background technique [0002] Water resources are very precious resources on the earth. As time goes by, more and more fresh water is reduced, making people less and less drinking water in their lives. In the modern urban landscape, natural approaches and artificial measures should be considered comprehensively in terms of water resource recycling. We need to maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and waterlogging, and promote Utilization of rainwater resources and ecological environment protection, coordinate the systematic nature of natural precipitation, surface water and groundwater, coordinate water supply, drainage and other water recycling links, and consider its complexity and long-term na...

AI Technical Summary

Problems solved by technology

[0003] The existing rainwater collection and reuse devices have poor collection capacity. After rainwater is collected, it is directly stored statically. After a long period of storage, the water quality will deteriorate, produce peculiar smell, and cannot be used again or the scope of use will be greatly reduced.
