Embodiment Construction

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, a residential area rainwater collection and utilization system includes rainwater collection facilities, rainwater transmission facilities, primary rain separation tank 14, sedimentation tank 8, clear water tank 9 and artificial rainwater landscape wetland 12.

[0024] The rainwater collection facilities include roof gutters 3, downpipes 2 and roadside shallow ditches 5. The roof gutter 3 collects the rainwater on the roof under the roof of the residential area. The rain pipe 2 is connected to the gutter 3 on the roof, and the rainwater flows through the rain pipe 2 to the rainwater transmission facility. The roadside shallow ditch 5 is a brick structure, and the surface is plastered with mortar. A cover plate can be laid above the roadside shallow ditch 5 to collect road rainwater. A culvert pipe 19 (commun...

Abstract

The invention provides a residential community rainwater collection and utilization system. The system comprises a rainwater collection facility, a rainwater transmission facility, a primary rain separation tank, a sedimentation tank and a clear water tank, and the rainwater collection facility is connected with an inlet of the primary rain separation tank through the rainwater transmission facility, an outlet of the primary rain separation tank is connected with an inlet of the sedimentation tank, and an outlet of the sedimentation tank is connected with an inlet of the clear water tank. Rainwater in a roof, a road surface and a greening area is collected through the rainwater collection facility, enters the primary rain separation tank and the sedimentation tank through the rainwater transmission facility, then is stored in the clean water tank after being purified, and is distributed to each water single element according to needs. The system is suitable for detention storage, infiltration, collecting, purifying and utilizing of the rainwater in buildings, greening areas and roads in urban communities in southern rainy areas.

Description

technical field [0001] The invention relates to a rainwater collection and utilization system in a residential area, belonging to the technical field of sponge city ecological construction engineering. Background technique [0002] In the current urbanization process, a large number of hardening and reconstruction treatments have been carried out on the original underlying surface of the city, which reduces the infiltration capacity of rainwater in the natural state, increases the total amount of surface runoff, and reduces the time of water collection. These will directly Induce frequent occurrence of urban waterlogging. In the southern region, due to more abundant rainfall, the problem of urban waterlogging is even more serious. Residential communities are an important part of the city. If the rainwater in the community can be infiltrated first and collected and utilized effectively, it will not only relieve the flood pressure of urban municipal pipelines and reduce the p...
