Embodiment 1

[0020] Such as figure 1 As shown, the sponge roof rainwater collection and utilization system includes a roof system, a pipeline system and a water storage system. The pipeline system is connected to the roof system and is used to transport the excess rainwater on the roof system to the water storage system. The rainwater flowing down from the pipeline system is also connected to the water storage system, which is used to irrigate vegetation and flush toilets with the rainwater in the water storage system. The roof system includes a roof (15), a vegetation layer (8), public facilities, and a rainwater collection filter. The vegetation layer (8) is laid on the roof (15), and has the functions of absorbing and storing rainwater, greening the environment, and purifying the air ; The public facility is set above the roof (15) to provide vegetation layer (8) management and leisure places; the edge of the roof (15) is provided with a rainwater collection filter port connected to the...

Abstract

A sponge roof rainwater collecting and using system comprises a roof system, a pipeline system and a water storage system, wherein the pipeline system is connected with the roof system and used for conveying redundant rainwater on the roof system to the water storage system, the water storage system is used for storing the rainwater flowing from the pipeline system, and the pipeline system is connected with the water storage system and uses the rainwater in the water storage system for vegetation irrigation and toilet flushing. The sponge roof rainwater collecting and using system has the remarkable advantages that the roof system effectively collects the rainwater, a vegetation layer preliminarily collects and uses the rainwater and has the filtering effect on the rainwater, and the vegetation layer effectively retain part of the rainwater, reduces rainwater runoff amount, and then reduces the drainage pressure of a rainwater pipe network; coverage of the vegetation layer is increased, the green area can be increased, air is purified, and the indoor temperature of a penthouse can be effectively adjusted.

Description

technical field [0001] The invention relates to a sponge roof rainwater collection and utilization system, which belongs to the field of water supply and drainage science and engineering. Background technique [0002] With the continuous occurrence of urban floods at home and abroad and the concept of sponge city, more and more people have begun to pay attention to the discharge and utilization of urban rainwater. However, it is difficult to improve the common problems of large urban rainwater runoff and low rainwater utilization rate at present. Most of the rainwater is directly discharged to form runoff instead of being used. At the same time, the reduction of urban green area and the destruction of ecological environment have attracted more and more people's attention to the improvement of living environment. Therefore, this system has very important significance for reducing rainwater runoff, improving rainwater utilization rate, increasing urban green area and improvin...
