Description

A high-rise building rainwater recycling device

technical field

The utility model relates to the field of water recovery and utilization, in particular to a high-rise building rainwater recovery and utilization device.

Background technique

Rainwater is regarded as "the water given by God", and its effective use has been paid more and more attention by people. China has abundant rainwater resources, with an average annual precipitation of 6.2* ^10.4 billion cubic meters, and the available water resources are huge. Currently, most cities in China On the one hand, there is a general shortage of water resources, and on the other hand, the precious rainwater resources have not been effectively utilized. Due to the rapid development of urbanization, impermeable areas such as roads and buildings have expanded. On the one hand, rainwater can no longer infiltrate into the ground to replenish groundwater, coupled with the serious overexploitation of groundwater, which deteriorates the water environment and ecological environment around the city; Urban water shortage, deterioration of water environment, destruction of ecological environment, and urban storm floods have become increasingly prominent. If in urban construction, we pay attention to the development of rainwater collection and utilization projects, and retain and use the rainwater that was originally drained, it will not only increase water resources, but also a good measure to save tap water. At the same time, through the extensive development of rainwater harvesting and utilization, because the rainwater is retained or seeped back into the ground, the drainage volume is reduced and the threat of urban flood disasters is reduced. Therefore, groundwater can be replenished, the water environment can be improved, and the ecological environment can be restored. It can be said that rainwater harvesting is one of the important measures for the sustainable use of urban water resources. The flowers, plants and trees next to the high-rise buildings in the residential area and the roadside are generally watered by mobile sprinklers. This irrigation method is time-consuming and labor-intensive, and the amount of water for one irrigation is limited.

Invention patent application number: 201110166888.2, application publication number CN 102839711 A, a rainwater collector, including a rainwater storage tank. The pipeline connected with the tank, and the rainwater storage tank is arranged at a position lower than the deflector. The rainwater collector provided by the invention can collect and concentrate rainwater in a larger area, and the collected rainwater can be simply treated to ensure long-term storage of the rainwater without pollution. The rainwater collector described in this invention is not tried for water storage in high-rise buildings. The rainwater collector is provided with a water storage tank, has no water outlet device, and cannot be buried underground. For cities with many high-rise buildings and tight land space, this invention cannot effectively solve the problem of high-rise buildings. Rainwater harvesting and recycling.
