The remaining end of the second three-way valve 7 is connected to an EDI continuous electrodeionization desalted water processor 8 through a pipeline, which is beneficial to achieving the effect of circulating and pre-treating water, so that the desalted water treatment system can be applicable to water of various water qualities, and thus greatly improves the applicable range of the desalted water treatment system.

[0013] In this implementation scheme, as shown in the attached Figure 2 figures, the water quality detection and neutralization component 5 includes a water quality detection box 51. A driving motor 52 is fixedly connected to the middle part of the upper part of the water quality detection box 51, and the lower end of the output shaft of the driving motor 52 penetrates into the interior of the water quality detection box 51. The lower end of the output shaft of the driving motor 52 is connected to a stirring rod 53 through a coupling; a water quality sensor 54 is hermetically and fixedly connected to the opening at the middle part of the lower part of the water quality detection box 51; a feed valve 55 is connected to the opening at the upper right side of the water quality detection box 51 through a pipeline; an input valve 56 is connected to the opening at the upper left side of the water quality detection box 51 through a pipeline; an output valve 57 is connected to the opening at the lower left side of the water quality detection box 51 through a pipeline.

[0014] In this implementation scheme, specifically, the input end of the input valve 56 is connected to the output end of the activated carbon filter cartridge 3 through a pipeline.

[0015] In this embodiment, specifically, the output end of the output valve 57 is connected to the input end of the water pump 6 through a pipeline.

[0016] In this embodiment, specifically, a PP filter element is installed inside the PP filter cartridge 1.

[0017] In this embodiment, specifically, a microfiltration membrane filter element is installed inside the microfiltration membrane filter cartridge 2.

[0018] In this embodiment, specifically, an activated carbon filter element is installed inside the activated carbon filter cartridge 3.

[0019] In this embodiment, specifically, the remaining end of the first three-way valve 4 is connected to the output end of an external water pump for water to be treated through a pipeline, and the water pump for water to be treated is electrically connected to an external control panel.

[0020] In this embodiment, specifically, the input end of the feed valve 55 is connected to the output end of an external pH adjustant delivery pump through a pipeline, and the pH adjustant delivery pump is electrically connected to an external control panel.

[0021] In this embodiment, specifically, the feed valve 55, the input valve 56, the output valve 57, the first three-way valve 4, and the second three-way valve 7 respectively adopt solenoid valves.

[0022] In this embodiment, specifically, the drive motor 52, the water quality sensor 54, the water pump 6, the EDI continuous electrodeionization water treatment device 8, the feed valve 55, the input valve 56, the output valve 57, the first three-way valve 4, and the second three-way valve 7 are respectively electrically connected to an external control panel.

[0023] When using this demineralized water treatment system, the operator can operate the external control panel to enter the water treatment mode. Subsequently, the control panel will automatically activate the first three-way valve 4, connecting the external raw water transfer pump to the PP filter cartridge 1. At the same time, it will control the input valve 56 to open, while the other valves remain closed. Then, the control panel will automatically control the raw water transfer pump to start, continuously injecting water into the PP filter cartridge 1. Subsequently, the water will successively pass through the microfiltration membrane filter cartridge 2 and the activated carbon filter cartridge 3, and enter the water quality detection tank 51 through the input valve 56 for storage. Through the PP filter cartridge 1, the microfiltration membrane filter cartridge 2, and the activated carbon filter cartridge 3, various impurities in the water can be filtered, thereby reducing substances such as organic matter, variable valence metals, and silicon dioxide in the water. After the raw water transfer pump has been working for a certain period of time, the control panel will automatically turn off the raw water transfer pump and close all valves at the same time. Then, the control panel will detect whether the water quality in the water quality detection tank 51 meets the requirements through the water quality sensor 54. If it meets the requirements, the control panel will automatically activate the second three-way valve 7, connecting the water pump 6 to the EDI continuous demineralized water processor 8. At the same time, it will control the output valve 57 and the water pump 6 to open. Subsequently, the water pump 6 will suck the water in the water quality detection tank 51 and inject it into the EDI continuous demineralized water processor 8 for treatment. If the water in the water quality detection tank 51 does not meet the requirements, the control panel will automatically activate the first three-way valve 4 and the second three-way valve 7, connecting the water pump 6 to the PP filter cartridge 1. At the same time, the water pump 6, the input valve 56, and the output valve 57 will be opened. At this time, the water pump 6 will inject the water in the water quality detection tank 51 back into the PP filter cartridge 1 again, and the water will successively pass through the microfiltration membrane filter cartridge 2 and the activated carbon filter cartridge 3, achieving the effect of circulating filtration until the water quality in the water quality detection tank 51 meets the standard. Subsequently, the control panel will automatically control the system to inject the water in the water quality detection tank 51 into the EDI continuous demineralized water processor 8 for treatment. Compared with the prior art, the utility model can pre-treat water, enabling water of various qualities to meet the requirements for entering the EDI continuous demineralized water processor 8. Furthermore, the demineralized water treatment system can be applicable to water of various qualities, greatly improving the applicable range of the demineralized water treatment system and achieving the effect of circulating pre-treated water. When the control panel detects that the pH value of the water is too high or too low through the water quality sensor 54, the control panel will automatically open the feed valve 55 and start the external pH adjustant transfer pump at the same time, injecting the corresponding pH adjustant into the water quality detection tank 51. Then, the control panel will start the drive motor 52 to drive the stirring rod 53 to stir the water until the water in the water quality detection tank 51 meets the pH value requirements. There are two pH adjustant transfer pumps, one for transporting alkaline pH adjustant and one for transporting acidic pH adjustant.
