Description

Multifunctional rainwater recycling device
Technical Field
The utility model relates to a retrieval and utilization technical field is collected to the rainwater, specifically is a multi-functional rainwater retrieval and utilization device.
Background
According to statistics, nearly 80% of cities in China have water shortage, and the north is particularly serious. Among them, colleges and universities become a big source of water resource waste and low utilization with huge water demand users and low water cost. At present, the number of students in schools is increasing dramatically year by year in China. The main water used in high-class school is from student dormitory building, teaching building, laboratory, library, etc., wherein the water consumption of student dormitory building accounts for 60% -70% of the total water consumption of school. The above water background is the starting point of the design of the utility model.
In addition, in the water consumption of the daily water heaters, the water consumption of the excrement and urine tank is higher than that of the toilet basin, and accounts for 70 percent of the total water consumption. This portion of the water is attributable to the range of applications for which the reclaimed water is used.
The rainwater is a valuable water resource, has light pollution, and plays an important role in adjusting and supplementing urban water resources and improving urban natural ecosystem. The rainwater collecting and recycling system is an effective technical approach for saving water and efficiently using water. The specific working principle is as follows: after the city receives rain, rainwater accessible collecting system collects, and roughly rain source can divide into two types, roof rainwater and ground rainwater. Wherein the roof rainwater is relatively clean, and impurity, silt and other pollutants are few, but reuse rate is higher. The rainwater is discharged into a water storage system after being subjected to flow discarding and simple filtering, purification treatment technologies such as a physicochemical method, a biochemical method, a physicochemical and biochemical combination method and the like are carried out, the properly treated rainwater can be used as domestic miscellaneous water, the water quality index of the rainwater is between that of upper water and lower water and is called reclaimed water, and the corresponding technology is called reclaimed water recycling technology.
The treated reclaimed water can be used for toilet flushing, plant irrigation and living sanitation. Among the total water consumption of various activities, the indoor water consumption accounts for about 30% of the total water consumption. Therefore, an indoor water supply and drainage engineering system is reformed to a certain degree, part of indoor water sources are replaced by purified and filtered rainwater, and a large part of domestic water can be saved.
At present, most of commonly used roof rainwater recycling technologies are centralized collection and utilization. The main working flow is that rainwater enters the initial stage flow discarding device through the vertical pipe, rainwater containing more impurities in the early stage of rainfall is discharged to the urban sewage pipeline through the initial stage flow discarding device, and the rainwater uniformly enters the urban sewage treatment plant for treatment and then is discharged. The clean rainwater which is discarded in the initial stage is required to be converged into a water storage tank through an independently arranged rainwater pipeline, and is pumped into a special pipe network through a water pump after being subjected to treatment procedures such as filtering, precipitation, secondary filtering, disinfection and the like in the tank, so that the rainwater can be used as non-drinking water in the aspects of family life, urban public or industrial production and the like.
However, at present, the practical significance of reclaimed water reuse in many areas is not clear, and the policy of encouraging reclaimed water is lacking. For a long time, the important function of reclaimed water recycling on maintaining and improving urban water environment is difficult to realize, and the problems of lack of technical resources, application experience, high equipment cost and the like are solved, so that a reclaimed water recycling system is not fully popularized and utilized in actual life.
