[0054] The working principle of the present utility model is as follows:

[0055] As Figure 1 shown in Figure 1 three series-connected filtration units are arranged in

Figure 4 The water is pumped by the intelligent water pump 13 and enters the first-stage 60-mesh filtration unit after entering this device. After about 5 s of water inlet, when the water level rises, it will flow into the middle filter cartridge 5 for the first filtration.

[0059] After the water after the first-stage filtration flows out, it flows into the second-stage 100-mesh filtration unit through the one-way valve 7. After a period of water inlet, when the water level rises, it will flow into the middle filter cartridge 5 for the second filtration. The filtered residue will fall into the cylinder body 4 outside the filter cartridge 5, and the filtered water will flow out through the water outlet pipe 9 in the middle of the filter cartridge 5. The filtered residue is discharged by starting the sewage discharge valve 11 every 50 minutes for 10 s.

[0060] After the water filtered at the third stage flows out, it passes through the one-way valve 7 and flows into the sterilization unit for ultraviolet disinfection and filtration. The sterilization unit is provided with an ultraviolet disinfection lamp 14. After a period of water inlet, the water body is in full contact with the ultraviolet disinfection lamp 14 for sterilization, and at the same time, the water level gradually rises. When it rises to the filter hole covered with a 200-mesh filter screen in the middle, filtration after sterilization is carried out. The residues after filtration will fall into the cylinder 4 outside the filter cylinder 5, and the filtered water flows out through the water outlet pipe 9 in the middle of the filter cylinder 5. After filtration, the sewage discharge valve 11 is started every 70 minutes to discharge the residues for 5 s.
