Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] The technical scheme of the invention consists of two parts: a green roof system and a rainwater collection system.

[0029] 1. Green roof system

[0030] The green roof system is a grass planting system installed on the roof. Its bottom layer is the roof structure layer 1, and the top of the roof structure layer 1 is sequentially provided with a waterproof layer 2, a root layer 3, a storage and drainage layer 4, and a filtration layer. Layer 5, light filler layer 6, planting soil layer 7 and vegetation layer 8; the light filler layer 6 is a mixed layer with a volume ratio of perlite and vermiculite of 2:1; the storage and drainage layer 4 is a light Mass storage drainage board; the filter layer 5 is a non-woven fabric structure;

[0031] The vegetation layer 8 and the planting soil layer 7 intercept and utilize rainwater, and the lightweight filler layer 6 ca...

Abstract

The invention discloses a roof rainwater collecting and recycling using system which comprises a green roof system and a rainwater collecting system. The bottommost layer of the green rood system is a roof structural layer, and a waterproof layer, a root-isolating layer, a water storage and drainage layer, a filtering layer, a light filler layer, a planting soil layer and a plant layer are sequentially arranged on the bottommost layer from bottom to top. The light filler layer is a mixed layer of perlite and vermiculite. The water storage and drainage layer is a light water storage and drainage plate. After being processed by the green roof system, the rainwater is stored into a water storage pool and then pumped to outside greenbelts or landscape facilities. The roof rainwater collecting and recycling using system can purify air and beautify environment, and compared with the prior art, is low in technical investment, high in economic benefit, and capable of improving environmental and social benefits.

Description

technical field [0001] The invention belongs to the field of urban water supply and drainage, and in particular relates to the application of green roofs and a roof rainwater collection and utilization system. Background technique [0002] With the development of society and the increase of population, the contradiction between the increase of demand for water resources and the shortage of water resources in our country is increasing day by day. Therefore, it is very important to make full use of all available water resources to improve the situation of water resources in our country. Existing studies have shown that the water quality of roof rainwater is relatively clean and can be directly used after simple treatment. The traditional roof rainwater utilization process is: roof rainwater collection→initial waste flow device→regulation pond→rainwater treatment device→clean water pond→greening use, groundwater recharge, etc. The problems faced by the utilization of roof rain...
