[0041] The working principle of the above embodiment is:

[0042] Filter materials such as ceramsite and activated carbon can be placed in sequence between adjacent partitions 6. The water flow will enter the bottom end of the empty slot 2 through the water inlet hole 12. Before passing through the water inlet hole 12, the water flow will be preliminarily filtered by gravel 17 and coal slag 18. The water flow entering the empty slot 2 will move upward through the through hole 5, and then flow from the inside to the outside through the water holes on the partition 6. During the flow, the water passes through the filter materials between the partitions 6 in sequence. After being filtered in layers by the filter materials, the water flows through the outermost partition 6 again to the external empty slot 2, and then flows out of the dam body 1 through the water outlet hole 13, and then the water flow filtration is completed.
