The filtered liquid in the filter box 1 is guided to the aeration tank 4 via the first water pipeline 2 and the first water pump 3, the aerated liquid in the aeration tank 4 is guided to the drug purification box 5 via the second water pipeline 6 and the second water pump 7, and the disinfected liquid in the drug purification box 5 is guided to the water storage tank 10 via the third water pipeline 8 and the third water pump 9.

In addition, filters are provided at the injection ends of the first water pipeline 2, the second water pipeline 6 and the third water pipeline 8 to prevent flocs in the liquid from entering the aeration tank 4, the reagent purification box 5 or the water storage tank 10 through the input pipeline.

In this embodiment, the filter box 1 includes a liquid injection pipe 100 connected thereto, a filter plate 103 and a multi-stage filter layer arranged inside the filter box 1 from top to bottom, and a water filter area 108 located below the multi-stage filter layer.

Specifically, a plurality of mesh holes are provided on the filter plate 103 . When the mine sewage passes through the filter plate 103 , the mesh holes can separate the mine sewage into solid and liquid.

The mine sewage enters the interior of the filter box 1 through the injection pipe 100. When the mine sewage contacts the filter hole plate 103, the large particles or large residues contained in the mine sewage can be filtered out through the filter hole plate 103. The sewage separated by the filter hole plate 103 falls under the filter hole plate 103, and the large particles or large residues separated by the filter hole plate 103 are retained on the filter hole plate 103 to achieve solid-liquid separation.

Optionally, the mesh size of the filter plate 103 is not greater than 2 mm.

Preferably, the mesh size of the filter plate 103 is 1 mm to 1.5 mm.

In this embodiment, the filter plate 103 is arranged inside the filter box 1 in a downwardly inclined shape.
