Description

A roof garden rainwater intelligent collection and utilization system

technical field

The invention relates to a roof garden rainwater intelligent collection and utilization system, which belongs to the technical field of rainwater recycling and utilization.

Background technique

In the prior art, rainwater collection, in its entirety, should be called "rainwater collection and utilization system", which refers to the collection and utilization of rainwater runoff collected from building roofs, roads, squares and other hardened surfaces, and after collection - water delivery - purification. Water—Storage and other channels accumulate rainwater to provide rainwater supply for greening, landscape water bodies, washing and groundwater sources, so as to achieve the purpose of comprehensive utilization of rainwater resources and water conservation. The supply of tap water in many cities and regions has been unable to keep pace with the pace of urbanization. The urban watering and greening, road flushing and other public water use and emerging water industries such as car washing have further increased the burden of tap water supply. However, in the rainy season every year, the flood of rainwater has caused great difficulties for urban drainage. The collection and utilization of rainwater just solves the two major problems brought to urban construction. Rainwater collection and utilization system has a wide range of significance, such as slowing down urban rainwater floods and groundwater level decline, controlling rainwater runoff pollution, and improving urban ecological environment. In daily life, the amount of rainwater accumulated on the roof cannot be underestimated. If this part of rainwater can be collected and reused, resources can be saved to a certain extent. Roof gardens not only have excellent cooling and heat insulation effects, but also can beautify the environment, purify the air, improve local microclimates, enrich the pitching landscape of the city, compensate for the green ground occupied by buildings, greatly improve the green coverage rate of the city, and improve people's living conditions. Living conditions and improving the quality of life are a kind of roofing form worthy of vigorous promotion. However, roof gardens require a large amount of water and use more water. Nowadays, with the increasing shortage of water resources, the maintenance of roof gardens is more stressful, and the general water storage unit is built underground. When the upper buildings or roof gardens need water, they need to The transportation from the ground to the roof is long, consumes a lot of energy, and is inconvenient for irrigation.

Patent publication number CN203256980U discloses a roof rainwater collection and resource utilization system, including a green roof system and a rainwater collection system; the bottom layer of the green roof system is a roof structure layer, and a waterproof layer is arranged on it from bottom to top. , root spacer layer, storage and drainage layer, filter layer, light filler layer, planting soil layer and vegetation layer; the lightweight filler layer is a mixed layer of perlite and vermiculite; the storage and drainage layer is a lightweight storage and drainage board. The rainwater is processed by the green roof system and stored in the reservoir, and then pumped by the water pump to the outdoor green space or landscape facilities. Rainwater utilization and practice in roof gardens mentioned that the design of rainwater collection system includes determining the roof drainage slope, collection area and rainwater purification measures. The rainwater from the roads and squares in the roof garden infiltrates into the drainage layer through the drainage channel set on its side; the collection of rainwater in the green space is divided into two parts. Rainwater flows into nearby drainage channels, shallow plant ditches or low places in green spaces, and then gradually seeps into the drainage layer. All rainwater entering the drainage layer is collected into the downpipe and flows into the underground reservoir. Application Publication No. CN105804151A discloses an intelligent roof garden rainwater collection and utilization system, including a planting layer and several humidity sensors embedded in the planting layer. One side of the planting layer is provided with a grid well, and the top of the grid well has a water inlet. A coarse grid cabinet is installed at a 90-degree angle, the spacing of the coarse grid is 6-10mm, and the grid area is greater than 0.6m". A fine grid book is installed in the grid well at an angle of 60-75 degrees, opposite to the direction of rainwater inflow. Installation, the bottom of the grid well is filled with a rainwater purification rubble layer, and one side of the rainwater purification rubble layer is sequentially connected with an aeration adjustment tank, a hydrolysis acidification tank, a contact oxidation tank, a biological aerated filter, a water storage tank and a storage tank. Liquid level adjustment tank. The invention realizes the collection, purification, storage and reuse of rainwater, and at the same time, it can keep a relatively suitable humidity environment in the planting layer all the time, improve the growth ability of plants, use solar energy to supply power, and save energy and protect the environment.

The research on rainwater utilization in China has a long history, but the development is relatively slow. Some theoretical research and practical exploration have only appeared in the past ten years. However, from the perspective of urban green space, there is no systematic theoretical guidance, and more of it just stays at the level of urban green space. The existing technology cannot reasonably utilize rainwater resources for most green space irrigation. The house garden not only has excellent cooling and heat insulation effect, but also can beautify the environment, purify the air, improve the local microclimate, and also enrich the pitching landscape of the city. It is a roofing form worthy of vigorous promotion. However, the existing roof gardens either focus on practicality, such as planting vegetables to meet the needs of life; or focus on ornamental properties, such as focusing on flowers and plants, which seriously weakens the environmental function of the roof garden and fails to integrate the economic value and environmental value of the house garden. organically combined with ecological value. Although the above-mentioned roof rainwater collection and resource utilization system can purify the air and beautify the environment, the soil in the planting soil layer will agglomerate during long-term use, which reduces the permeability of plant roots and makes If the respiration of root cells is weakened, it is not conducive to the transpiration of the roots, so that the roots cannot absorb the mineral elements in the soil, which is not conducive to the growth of plants. To sum up: the existing technologies use some environmental protection technologies such as solar energy, but still fail to achieve certain economic benefits, the collection and irrigation of rainwater are not scientific enough, some irrigation data are not accurate enough, and the rainwater has not been clearly classified and utilized after purification, To some extent, resources are not used properly. To this end, it is necessary to design corresponding technical solutions to solve it.
