[0021] See appendix Figure 1 To be continued Figure 3 As shown, a water treatment system for a water supply network includes a first water tank 1, multiple first ultrafiltration membranes 21, multiple second ultrafiltration membranes 22, a filter tank 3, two softening tanks 4, and a second water tank 5. The multiple first ultrafiltration membranes 21 are connected in sequence, the multiple second ultrafiltration membranes 22 are connected in sequence, and the two softening tanks 4 are connected front to back in sequence. The bottom of the first water tank 1 is connected to a first drain pipe 11, which is connected to the filter tank 3 and the upstream softening tank 4. The filter tank 3 is connected to a first water pump 61 and the upstream first ultrafiltration membrane 21. The downstream first ultrafiltration membrane 21 is connected to a second water pump 62, which is connected to the upstream second ultrafiltration membrane 22. The downstream second ultrafiltration membrane 22 is connected to the first water pump 61. The upstream softening tank 4 is equipped with a first switch valve 81, and the downstream softening tank 4 is connected to the second water tank 5.

[0022] In this embodiment, each of the first ultrafiltration membranes 21 is connected to a first guide tube 71 at its top, and the first guide tube 71 is connected to a second water pump 62.

[0023] In this embodiment, each second ultrafiltration membrane 22 is connected to a second guide pipe 72 at its top. The second guide pipe 72 is connected to a third water pump 63. The third water pump 63 is connected to an ultrapure water membrane stack device 9. The ultrapure water membrane stack device 9 is connected to the third guide pipe 73. The third guide pipe 73 is connected to the top of the first water tank 1. The third guide pipe 73 is connected to a fourth guide pipe 74. A fifth guide pipe 75 is connected between the second water pump 62 and the second ultrafiltration membrane 22 located at the uppermost end. The fourth guide pipe 74 is connected to the fifth guide pipe 75. A second switching valve 82 is provided on the fourth guide pipe 74. A first guide pipe 71 is connected to the fifth guide pipe 75. A third switching valve 83 is provided on the fifth guide pipe 75.

[0024] In this embodiment, flow meters 84 are installed on the first guide pipe 71, the second guide pipe 72, the third guide pipe 73, the fourth guide pipe 74, and the fifth guide pipe 75. The flow meters 84 have remote communication functions and can transmit the data detected by the flow meters 84 to a remote terminal in real time, so that operators can judge the water supply status of the water supply network based on the flow meters 84.

[0025] In this embodiment, a first output pipe 52 is connected between the downstream softening tank 4 and the second water tank 5, and a fourth water pump 64 is installed on the first output pipe 52.

[0026] In this embodiment, a softening head 41 is provided on the top of the softening tank 4.

[0027] In this embodiment, the first water tank 1 is connected to the first water inlet pipe 12.

[0028] In this embodiment, the second water tank 5 is connected to a second drain pipe 51.

[0029] In this embodiment, the water treatment process is as follows: when the working pressure of the first ultrafiltration membrane 21 or the second ultrafiltration membrane 22 reaches the set threshold, the first switch valve 81 is closed to stop the raw water from entering the softening tank 4 located upstream. Then, the first water pump 61 is started. The raw water in the first water tank 1 is transported to the filter tank 3 through the first drain pipe 11 and then to the first water pump 61. The first water pump 61 transports the raw water to the first ultrafiltration membrane 21 for forward filtration. The filtered water is transported to the third guide pipe 73 through the fifth guide pipe 75 and the fourth guide pipe 74. The first guide pipe 71 returns a portion of the filtered water from the multiple first ultrafiltration membranes 21 to the second water pump 62. Then, the third switch valve 83 is opened, and the water is transported to the second ultrafiltration membrane 22 through the fifth guide pipe 7 for joint cleaning. The cleaned filtered water is then transported to the third water pump 63 through the second guide pipe 72. The third water pump 63 transports the water to the ultrapure water membrane stack equipment 9 for filtration. After filtration, the water is transported to the third guide pipe 73 and then back to the first water tank 1. When the pressure difference between the inlet and outlet of the first ultrafiltration membrane 21 and the second ultrafiltration membrane 22 returns to 1.1 times the initial value, the second water pump 62 is turned off and the first switch valve 81 is turned on to restore normal water production and supply water to the softening tank 4 located upstream. After the filtered water is softened by the two softening tanks 4, the fourth water pump 64 is started to transport the softened water to the second water tank 5.

[0030] In this way, the water between the first water tank 1 and the second water tank 5 can be filtered and transported between each other.

[0031] The water in the second water tank 2 can also be filtered by the first ultrafiltration membrane 21 and the second ultrafiltration membrane 22, so that the first water tank 1 and the second water tank 5 can deliver the filtered water to the water supply network.

[0032] Meanwhile, by controlling the first switching valve 81, the second switching valve 82, the third switching valve 83, and the corresponding first water pump 61, the second water pump 62, and the third water pump 63, in conjunction with the ultrapure water membrane stack equipment 9, backwashing of the first ultrafiltration membrane 21 and the second ultrafiltration membrane 22 can be achieved.

[0033] In the water treatment process of this embodiment, the flow meter with communication function monitors and collects relevant data in real time, which can obtain the status of the water treatment process. This allows for the collection of monitoring data on the water supply network, enabling staff to obtain relevant data and determine the status of the water supply network without having to go to the site.

[0034] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
