Example

As shown in FIG. 1 , a biological filter tank with a filter water distribution plate in this embodiment includes a tank body 1, the cross section of the tank body 1 is rectangular, and the tank body 1 is provided with a filter material layer 6 and a supporting layer 7. The supporting layer 7 is fixed on the inner wall of the pool body 1, the filter material layer is supported on the supporting layer 7, and the supporting layer 7 is provided with a plurality of through holes, so that the sewage passes through the supporting layer after being filtered and reacted by the filter material layer. Layer 7, there is a partial space at the bottom of the supporting layer 7 to provide storage space for the sewage after passing through the supporting layer 7.

In this embodiment, one side of the opening of the pool body 1 is provided with a water inlet pipe 5, and one side of the pool body 1 is provided with a water outlet pipe 8 at a position below the supporting layer.

As shown in FIG. 2 , in this embodiment, the top of the pool body 1 is open, the edge of the opening is provided with a groove, and the opening of the pool body 1 is provided with a water distribution plate 2 . As shown in FIG. 3 , the cross section of the water distribution plate 2 is provided. It is rectangular, and the water distribution plate 2 is in the shape of a groove, and the edge is provided with a hanging edge extending to the outside. The water distribution plate 2 is supported at the opening of the pool body 1 through the cooperation of the hanging edge and the groove.
