[0029] In this embodiment, the system includes a multi-stage cylinder, and the specific number of stages of the multi-stage cylinder can be set according to actual conditions. In this embodiment, the multi-stage cylinder includes a first cylinder 1, a second cylinder 2 and a third cylinder 3 that are interconnected.

[0034] Specifically, the first filter assembly 81 includes a coarse pebble layer 811 disposed at the bottom of the first cylinder 1 , and a first filter layer 812 located above the coarse pebble layer 811 .

[0035] The water outlet end of the water inlet pipe 4 located in the first cylinder 1 is left in the coarse pebble layer 811 , and the water outlet end of the water inlet pipe 4 is provided with a first bell mouth 41 .

[0036] In this embodiment, the filter assembly includes a first filter assembly 81 , a second filter assembly 82 and a third filter assembly 83 .

[0037] The first filter assembly 81 is arranged in the first cylinder 1, and the first filter assembly 81 includes a coarse pebble layer 811 arranged at the bottom of the first cylinder 1. The coarse pebble layer 811 uses pebbles with a diameter of 2-3 cm. A first filter layer 812 is placed on the coarse pebble layer 811, and the mesh number of the first filter layer 812 is 100-200 mesh.

[0038] The outlet end of the water inlet pipe 4 located in the first cylinder 1 is left in the coarse pebble layer 811, and the outlet end of the water inlet pipe 4 is provided with a first bell mouth 41, so that when the water body in the mountain environment is pumped into the first cylinder 1, the water flow first enters the coarse pebble layer 811, and the first bell mouth 41 can reduce the water inlet pressure and improve the sedimentation efficiency, so that the water flow passes through the coarse pebble layer 811 and the first filter layer 812 in turn.

[0044] Furthermore, a second bell mouth 91 is provided at the water outlet end of the first overflow pipe 9. The second bell mouth 91 can reduce the water inlet pressure at the water outlet end of the first overflow pipe 9, thereby improving the sedimentation efficiency.

[0048] In this embodiment, the third filter component 83 is arranged in the third cylinder 3, and the third filter component 83 is arranged in the second filter layer 831 at the bottom of the third cylinder 3. The mesh number of the second filter layer 831 is 100-200 mesh. The second filter cotton layer 832 is placed on the second filter layer 831, and the second filter cotton layer 832 uses synthetic fiber filter cotton.

[0049] The second overflow port 22 of the second cylinder 2 is connected to the third water inlet 31 of the third cylinder 3 through the second overflow pipe 10. The height of the second overflow port 22 is the same as that of the third water inlet 31, and the height of the second overflow port 22 is less than that of the second water inlet 21. Therefore, after the water in the second cylinder 2 is precipitated and filtered, when the liquid level rises to the second overflow port 22, the water in the second cylinder 2 flows to the third cylinder 3 through the second overflow pipe 10, and the water outlet end of the second overflow pipe 10 is left in the second filter layer 831, so that the flowing water directly flows into the second filter layer 831 for sedimentation and filtration. The second filter cotton layer 832 can block the suspended matter in the water again to prevent the suspended matter from overflowing into the lower sedimentation tank, thereby forming a third fine filtration sedimentation.

[0050] Furthermore, a third bell mouth 101 is provided at the water outlet of the second overflow pipe 10. The third bell mouth 101 can reduce the water inlet pressure at the water outlet of the second overflow pipe 10, thereby improving the sedimentation efficiency.
