Description

Rainwater collecting and recycling device and using method thereof Technical Field The invention relates to the technical field of rainwater collection, in particular to a rainwater collection and recycling device and a using method thereof. Background In the field of architecture, a roof is used as an important interface for interaction between a building and an external environment, and not only plays roles of sun shading, water proofing, heat preservation and other basic functions, but also serves as a key carrier for collecting rainwater resources. With the deep application of concepts such as green buildings, sponge cities and the like in building design, a rainwater collection system has become an important component of modern building water supply and drainage systems and ecological design. The occupied area of the substation area is large, the total sum of the roof areas of the buildings is quite considerable, and excellent conditions are provided for rainwater collection. The operation and maintenance of the transformer substation also needs a large amount of miscellaneous water, such as greening irrigation of a station area, road surface flushing of a site and an equipment area, water supplementing of a fire-fighting water pool and the like. At present, the water is mostly dependent on municipal pipe network, the cost is high, and the resource circulation concept of green building is not reflected. However, the transformer substation has special requirements on water safety, and particularly when the transformer substation is used for a fire-fighting standby water source, the water quality must be ensured, the traditional rainwater collection system is difficult to match with the building structure and load requirements of the transformer substation and the harsh water quality standard, and intelligent management is lacking, so that the system cannot be effectively linked with the fire-fighting and irrigation systems of the transformer substation. The existing rainwater collection device adapting to the building roof still has the following technical defects related to the architecture profession in the aspects of cooperation with a building structure, integration of a building water supply and drainage system and maintenance suitability of a building environment: Firstly, the adaptability of the roof structure of the building is poor, the safety and the functionality of the building are damaged, the traditional rainwater collecting device mostly adopts a mounting mode of a roof fixing support and a rainwater collecting groove, the support needs to penetrate a roof waterproof layer to be fixed with an insulating layer, the risk of roof leakage is easily increased, the building waterproof design specification is violated, the gravity center of the partially foldable device is deviated after the partially foldable device is unfolded, the partially foldable device is not matched with the roof load design, and the deformation of the roof structure is easily caused after the partially foldable device is used for a long time. And meanwhile, the design of regulating and controlling the runoff of the rainwater is lacking, the rainwater is easy to flow backward to the building room or overflow of a roof water outlet in heavy rain weather, and the pressure of a drainage system of the building roof is increased. And thirdly, the device is disjointed with the maintenance requirement of the building environment, and affects the life cycle cost of the building, namely, from the viewpoint of the maintenance of the building environment, the existing device has insufficient pretreatment capability and poor water quality stability after rainwater purification, is easy to cause soil hardening when used for greening irrigation, and is easy to block sanitary ware when used for flushing toilet. Therefore, a rainwater collecting and recycling device which is matched with a building roof structure, a building water supply and drainage system and a building environment maintenance and adaptation is required to be designed so as to meet the requirement of a green building on water resource recycling and improve the ecological performance and operation and maintenance safety of the building.
