Figure 1 As shown, it includes a clean water tank 1, a first water supply line, a second water supply line, a recycling main pipe, a first ultraviolet germicidal lamp 2, a first filter 3 and an ozone generator 4. The water outlet 103 of the clean water tank 1 is connected to the first water supply line and the second water supply line respectively, and the first water supply line and the second water supply line are connected to an ozone detector 5 respectively. The first water supply line and the second water supply line are connected to the water inlet 102 of the clean water tank 1 through the recycling main pipe respectively to achieve circulation. The recycling main pipe is connected with the first ultraviolet germicidal lamp 2, the first filter 3 and the ozone generator 4 in sequence. The first ultraviolet germicidal lamp 2 is located downstream of the first water supply line and the second water supply line, and the ozone generator 4 is located upstream of the inlet of the clean water tank 1.

[0025] The first water supply line and the second water supply line have the same structure, including a conductivity detector 11, a water supply pump 12, a second filter 13, an online pressure sensor 14, a voltage stabilizer 15, a water use end and an electric gate 16 connected in sequence. One end of the water supply pump 12 is connected to the clean water tank 1, and a conductivity detector 11 is provided between the water supply pump 12 and the clean water tank 1, and an electric valve is provided between the conductivity detector 11 and the clean water tank 1. The other end of the water supply pump 12 is connected to the water use end, and the second filter 13 and the voltage stabilizer 15 are connected in sequence between the water supply pump 12 and the water use end. A pressure display 17 is provided on the first filter 3 and the second filter 13, an ozone detector 5 is connected between the water supply pump 12 and the second filter 13, and an electric valve is provided between the ozone detector 5 and the water supply pump 12 and the second filter 13. An online pressure sensor 14 is connected between the second filter 13 and the voltage stabilizer 15, an electric valve is provided between the voltage stabilizer 15 and the water use end, and the water use end is connected to the electric gate 16, which is connected to the first ultraviolet germicidal lamp 2.

[0026] The clean water tank 1 includes a box body 101, a water inlet 102 and a water outlet 103. The top of the box body 101 is provided with a water inlet 102, and the ozone generator 4 is connected to the water inlet 102 through a pipeline. The bottom of the box body 101 is provided with a water outlet 103, and the water outlet 103 is connected to the water supply pump 12 on the first water supply line and the second water supply line through corresponding electric valves. A second ultraviolet sterilization lamp 105 is provided at the top of the inner wall of the box body 101, and a liquid level detector 106 is provided at the bottom of the inner wall of the box body 101, which is convenient for visually detecting the water level inside the box body 101. The bottom of the box body 101 is connected to a sewage pipe, and an electric valve is provided on the sewage pipe.

[0027] More specifically, after the tap water is processed by the front-end membrane system, the produced water comes into the clean water tank 1 with the second ultraviolet sterilization lamp 105 built in. The produced water after sterilization is respectively sent to different water-using ends through the water supply pump 1 12 and the water supply pump 2 12. According to the different water-using end requirements of users, such as: the number of water-using ends, different water consumption, different water-using end pressures, etc., water supply pumps 12 with different parameters are configured. A core-type second filter 13, an online pressure sensor 14, a voltage stabilizer 15, valves and other equipment are set between the water supply pump 12 and the water-using end. According to the data fed back by the online detection instrument, the PLC control system adjusts the pump frequency and the electric valve opening in real time to accurately meet the needs of different water-using ends.

[0028] On the premise of solving the needs of different water users, healthy and safe drinking water is the core value of our equipment. For this reason, we have set up a live water system with multiple protections. Through the PLC automatic control program, the drinking water in the pipeline is kept in a live state, and an inactivation and sterilization device is configured on the recycling main pipe to ensure the quality of drinking water. When drinking water passes through the user end, it will come into contact with the air for a short time, causing a certain degree of pollution to the drinking water in the network pipe. After the drinking water flows into the return water main, the first ultraviolet sterilization lamp 2, the core first filter 3 and the ozone generator 4 on the return water main are used to eliminate harmful substances in the return water. The drinking water returned to the clean water tank 1 is treated with the front-end membrane system to produce water, which is sent to the water user end through the water supply pump 12. This reciprocating process makes the drinking water healthy, safe and reliable.
