Description

Residential rainwater comprehensive utilization system device

technical field

The utility model belongs to the technical field of rainwater collection and reuse, in particular to a residential rainwater comprehensive utilization system device.

Background technique

China is a country that lacks water resources very much. The per capita water resource is only 2220 m ³ , which is 1/4 of the world's per capita level. It is listed as one of the 13 water-poor countries by the United Nations. The unbalanced distribution of water resources in time and space has further exacerbated the contradiction of water use. Due to the shortage of water resources and the overexploitation of groundwater, the ground subsides, buildings are damaged to varying degrees, and it is more difficult to control floods and waterlogging in cities. Urban rainwater utilization is an important measure to solve the shortage of urban water resources, reduce urban floods, improve urban ecological environment, and realize sustainable utilization of water resources. Many cities in the United States, Germany, India and other countries have begun to collect rainwater from roofs and platforms for flushing toilets, greening lawns, and building artificial landscapes. Many cities in the United States have established rainwater harvesting and utilization systems. When repairing urban water supply facilities, the rainwater harvesting and utilization systems are activated to ensure that citizens' water use will not be interrupted. In the suburbs and villages of the United States, most people live in single-family buildings with convenient conditions for rainwater collection and utilization. The collection and utilization of rainwater has attracted more and more attention. In some areas of Texas, rainwater is often collected to solve people's daily water use. The use of rainwater in German households is mainly to collect rainwater through the roof, and the rainwater enters the water storage tank or storage tank through pipes and filtering devices. Using rainwater from a cistern or cistern requires a pressure device to pump the water to the toilet or garden. Many households in India directly introduce rainwater from their roofs to the cistern in the courtyard. Usually, the rainwater collected in one rainy season can basically meet the water requirements of a family throughout the year. The gutters are used to receive the rainwater flowing down from the roof, and then enter the water storage tank on the ground through the conduit. In some open areas of the village, farmers will use cement, bricks and other materials to build some simple water storage tanks, which are mainly used for crop irrigation.

With the rapid development of social economy and the acceleration of urbanization, the utilization of rainwater resources is imperative. Utilization of rainwater resources will be an effective measure for cities to develop water resources, save water, reduce urban flood disasters, alleviate the burden of drainage pipes, reduce pollution loads, and improve urban water environment conditions. It is of great significance to improve the urban ecological environment, alleviate the tension of water resources and sustainable economic and social development.

In order to alleviate the water crisis, the development and utilization of rainwater resources has become an important way to solve the water crisis in many countries and regions. Among them, the roof is the most commonly used rainwater collection surface in residential quarters. Roof rainwater has good water quality, large runoff, and is easy to collect and utilize. It is an important way to collect and utilize rainwater in residential quarters. The roof as a rain collection surface can maximize the use of rainwater resources through collection, filtration, water delivery, storage, and recharge systems. This system can be set as a decentralized system for a single building, or it can be centralized in a building group or community The rational use of rainwater resources can save water resources and reduce the burden on urban drainage facilities. The reuse of rainwater after treatment can reduce the water consumption of tap water and reduce the cost of urban water diversion and water purification. The purified rainwater can be used for various purposes such as irrigating green spaces, flushing toilets, sprinkling roads and replenishing groundwater. At present, my country is also conducting research, development and utilization of this technology, such as:
