Detailed ways

Example:

The principle diagram of the utility model is shown in Figure 1. The rainwater collection and utilization system of the present utility model includes a rainwater collection pool 1, an automatic cleaning water filter 2, a clear water pool 3, and a rainwater discarding device 4, which are used to collect roof The rainwater discarding flow device 4 of rainwater is arranged on the podium roof, and the outlet of the rainwater discarding device 4 communicates with the water inlet of the rainwater collection tank 1, and the water outlet of the rainwater collection tank 1 communicates with the water inlet of the automatic cleaning water filter 2 , the water outlet of the automatic cleaning water filter 2 communicates with the water inlet of the clear water pool 3. the

The above-mentioned self-cleaning water filter 2 utilizes the clear water filtered out by itself to self-clean the filter screen through the internal pressure difference. the

In this embodiment, the above-mentioned rainwater discarding device 4 collects rainwater through the rainwater gutter provided on one side of the roof. the

The working principle of the utility model is as follows: the initial roof rainwater flows through the rainwater abandonment device 4 and then is discharged into the rainwater collection tank 1. After the rainwater is collected and precipitated in the rainwater collection tank 1, impurities are further filtered through the automatic cleaning water filter 2. , The self-cleaning water filter 2 uses the clear water filtered by itself to self-clean the filter screen through the internal pressure difference, without any external energy. After the rainwater is filtered, it enters the rainwater clear water pool 3 for storage. the

Natural rainwater has less organic pollution and low hardness, but due to the usual natural dustfall, the initial rainwater formed by falling on the roof is still polluting to a certain extent. Rainwater runoff has an obvious scouring effect, that is, in most cases, pollutants are concentrated in the initial few millimeters of rainfall. Controlling the initial rainwater can effectively control most of the pollutants in each rainfall runoff. The utility model adopts a self-controlled initial rainwater abandonment device in the initial rainwater control method. The self-control abandonment device has the function of automatically switching the rainwater abandonment pipe and the collection pipe, and has the function of controlling and adjusting the interval time of the abandonment flow. When the rainy season is frequent, the interval time of the initial rainwater abandonment flow can be automatically extended, and it can be directly connected to the pipe through the flange. , Easy to install, small in size, saving space. If the utility model is used in areas with frequent rainfall in the rainy season, the quality of the collected rainwater is better, and the water project of the rainwater reuse system designed by the utility model is only for greening and sprinkling, which has lower requirements on water quality. In addition, considering the random rainfall In order to avoid frequent idleness of rainwater purification facilities, the utility model adopts a relatively simple treatment process: the rainwater enters the collection pool for precipitation after being discarded at the initial stage, and then enters the clear water pool through the filter store. Since the rainwater collection and reuse device is centrally installed on the sky of the podium, and the water supply system can adopt the method of upward and downward supply, the system of the utility model can meet the water pressure requirements of the outdoor greening water on the first floor without additional water supply booster. Pressure equipment reduces equipment investment and makes the system more energy-efficient. Due to the use of the rainwater collection system of the utility model, the sky surface adopts a single slope for drainage, and the rainwater is collected through the rainwater side ditch arranged on one side, which reduces the rainwater standpipes and suspended pipes, and saves pipe materials. the
