[0035] The first filter material tank 3 is provided with a first upper water distributor 31 and a first lower water distributor 32. The first upper water distributor 31 and the first lower water distributor 32 are both connected to the first control valve 5. The first lower water distributor 32 extends to the bottom of the first filter material tank 3. The first upper water distributor 31 is sleeved on the outside of the first lower water distributor 32.

[0036] The second filter material tank 4 is provided with a second upper water distributor 41 and a second lower water distributor 42.

[0037] Both the first and second control valves 5 and 6 have three operating modes (normal filtration, forward flushing, and reverse flushing). Adjusting the operating mode of the control valves adjusts the direction of water flow within the filter tank. Regular backwashing and forward flushing of the filter tank are crucial to removing sediment, particulate matter, and other contaminants that have accumulated within the filter layer. This is crucial to restoring the tank's filtration capacity.

[0038] Normal filtration: Water passes through the first control valve interface 51, the first upper water distributor 31, the first lower water distributor 32, the first control valve interface 52, the second control valve interface 61, the second upper water distributor 41, the second lower water distributor 42, and the second control valve interface 62 in sequence;

[0039] Forward flushing: Water passes through the first control valve interface 51, the first upper water distributor 31, the first lower water distributor 32, the first control valve interface 53 in sequence, and then passes through the second control valve interface 61, the second upper water distributor 41, the second lower water distributor 42, and the second control valve interface 63 in sequence;

[0041] The first filter material tank 3 is filled with a manganese sand layer 33 , a garnet layer 34 , a fine quartz sand layer 35 and a coarse quartz sand layer 36 in sequence from top to bottom.

[0042] Four layers of sand and gravel filter materials are stacked from bottom to top in the first filter material tank 3.

[0043] The bottom layer is composed of coarse quartz sand with a particle size of 4-8 mm, and the upper layer of the coarse quartz sand layer 36 is composed of fine quartz sand with a particle size of 1-2 mm. The two different particle sizes of quartz sand serve as the base of the entire filter material combination to prevent the finer particle size filter material in the upper layer from clogging the central pipe.

[0044] The upper layer of the fine quartz sand layer 35 is piled with garnets of 0.3-0.6 mm. The garnets of uniform size are freely piled up to form narrow water flow channels, which can effectively intercept the sediment and particles in the raw water, thereby reducing the turbidity of the raw water.

[0045] The top layer of the first filter tank 3 is piled with manganese sand, which has strong oxidizing properties and can remove most of the Fe2+ and Mn2+ ions in the raw water.

[0046] Furthermore, in another embodiment, the second filter material tank 4 is filled with activated carbon 43 .

[0047] Coconut shell activated carbon is accumulated in the second filter material tank 4. The coconut shell activated carbon can effectively absorb some organic matter in the raw water and remove the color and odor of the raw water.

[0048] Furthermore, in another embodiment, the first control valve 5 includes a first control valve interface three 53, the first control valve interface three 53 is connected to a first drain pipe, the box body 1 is provided with a first drain port 12, the first drain pipe extends to the outside of the box body 1 through the first drain port 12, the second control valve 6 includes a second control valve interface three 63, the second control valve interface three 63 is connected to a second drain pipe, the box body 1 is provided with a second drain port 13, the second drain pipe extends to the outside of the box body 1 through the second drain port 3.

[0049] The first sewage pipe and the second sewage pipe are provided to discharge sewage.

[0050] Furthermore, in another embodiment, the sterilizer 7 is a UVC LED sterilization lamp.

[0051] After the raw water is filtered through two filter tanks, it enters the UVC LED sterilization lamp for sterilization, which can remove more than 99% of the total coliform bacteria in the raw water.

[0052] The whole machine uses excellent filter material ratio and LED sterilization technology to reduce turbidity, Fe2+, and Mn2+ in raw water, remove discoloration, odor, and bacterial contamination in the water, and can efficiently and reliably ensure the safety of users' water use.
