Further, the infusion pipeline 12, the reflux pipeline 13 and the premixing pipeline 14 are all provided with valves 9, that is, the infusion control of the infusion pipeline 12, the reflux pipeline 13 and the premixing pipeline 14 is realized by the setting of the valve 9. At the same time, an EC detector 4 is provided on the premixing pipeline 14, and a plurality of mesh filter elements 8 are evenly distributed at the output end of the premixing pipeline 14. Furthermore, a pH monitor 11 is provided on one side of the ultraviolet disinfection instrument 10, and the ultraviolet disinfection instrument 10 and the pH monitor 11 are both provided at one end of the reflux pipeline 13 connected to the output end of the infusion pipeline 12.

[0027] Specifically, the implementation process of the automatic cleaning system inside the disinfection machine in this embodiment is as follows:

[0028] Step 1: Initial preparation.

[0029] 1) Ensure that sufficient return liquid has been collected in the collection pool 1 for centralized disinfection, and ensure that acid liquid of appropriate concentration is prepared in the acid liquid pool 2. It is worth noting that the acid liquid in this embodiment can be selected to be 38% diluted nitric acid.

[0030] 2) Check whether the valves 9, pressure gauge 6, EC detector 4, UV disinfector 10 and pH monitor 11 are in normal working condition to ensure that the subsequent steps can operate normally.

[0031] 3) Start the sewage pump 5 and monitor the pressure in the infusion pipeline 12 through the pressure gauge 6 to ensure that the pressure is maintained at an appropriate level. In this embodiment, the pressure in the infusion pipeline 12 is maintained at 3.5 bar.

[0032] Step 2: Liquid return circulation and treatment.

[0033] 1) Open valve 9 to allow the return liquid in collection tank 1 to be fed into premixing unit 16 through liquid infusion pipe 12. During this process, EC detector 4 monitors the conductivity of the return liquid in real time for subsequent adjustment.

[0034] 2) The acid pump 7 is started to send the acid in the acid tank 2 to the premixing pipe 14 at the front end of the filtration unit 17 through the acid adding pipe 15, and mixes with the return liquid to adjust the pH value and soften the water quality. It is worth noting that the pH value of the return liquid needs to be monitored in this process to ensure the acidification effect.

[0035] 3) The mixed liquid then enters the filtration unit 17, where it passes through a plurality of mesh filter elements 8 to remove suspended solids and large particle impurities. It is worth noting that the filter element 8 needs to be backwashed regularly, that is, the filtrate is sent back to the collection tank 1 or the recovery tank 3 using the reflux pipe 13 to reduce losses.

[0036] 4) The filtered liquid enters the disinfection unit 18 and is disinfected by the ultraviolet disinfector 10 to eliminate pathogens. At the same time, the pH monitor 11 monitors the pH value of the disinfected water to ensure that the water quality is suitable for irrigation again.

[0037] Step 3: Recycle and recycle.

[0038] The disinfected water can be sent back to the inlet of the infusion pipe 12 through the return pipe 13 to form a closed loop, or directly introduced into the recovery tank 3 as needed to prepare for the next round of irrigation.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
