The utility model has the advantages that:
the utility model discloses a sewage slowly gets into in the water distribution plate through the inlet tube in the biological filter, because the hole edge that falls into water on the water distribution plate highly is higher than the water distribution plate bottom surface, so sewage stops in the water distribution plate, and the liquid level slowly rises, when the liquid level is higher than the hole edge that falls into water, sewage flows down from the hole that falls into water, get into the precoat, because need filterable solid pollutant in the sewage, certain volume has, so partial solid pollutant is blockked by the hole that falls into water, and because the water velocity is slow, so solid pollutant is difficult for being washed into the hole that falls into water by rivers, when water distribution plate surface pollutant gathers certain quantity, take off the water distribution plate and wash, because the pollutant gathers on the water distribution plate surface, it.
The utility model discloses be equipped with the serration plate at the hole edge that falls into water, sewage flows into the hole that falls into water from the sawtooth bottom, and the sawtooth can be strengthened the effect of blockking to solid pollutant.

In the figure: 1-a pool body, 2-a water distribution plate, 3-a water falling hole, 4-a hanging edge, 5-a water inlet pipe, 6-a filter material layer, 7-a supporting layer, 8-a water outlet pipe and 9-a serrated plate.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
As shown in fig. 1, the biofilter with the filtering and water distributing plate of the present embodiment includes a tank body 1, the cross section of the tank body 1 is rectangular, a filter material layer 6 and a support layer 7 are disposed in the tank body 1, the support layer 7 is fixed on the inner wall of the tank body 1, the filter material layer is supported on the support layer 7, the support layer 7 is provided with a plurality of through holes, so that sewage passes through the support layer 7 after being filtered and reacted by the filter material layer, and a partial space is left at the bottom of the support layer 7 to provide a storage space for the sewage after passing through the support layer 7.
In this embodiment, a water inlet pipe 5 is arranged at one side of the opening of the tank body 1, and a water outlet pipe 8 is arranged at one side of the tank body 1 below the supporting layer.
Referring to fig. 2, in this embodiment, the top of the tank body 1 is open, a groove is formed at the edge of the opening, and a water distribution plate 2 is disposed at the opening of the tank body 1, referring to fig. 3, the cross section of the water distribution plate 2 is rectangular, the water distribution plate 2 is groove-shaped, a hanging edge extending outward is disposed at the edge, and the water distribution plate 2 is supported at the opening of the tank body 1 through the matching of the hanging edge and the groove.
The bottom of the groove of the water distribution plate 2 is uniformly provided with a plurality of bosses, the bosses are provided with water falling holes 3, the water falling holes 3 penetrate through the bosses and the water distribution plate 2 from top to bottom, the edge of each water falling hole 3 is higher than the bottom of the groove of the water distribution plate 2, and the edge of each water falling hole 3 is provided with a serrated plate 9 along the circumferential direction of the water falling hole.
In the embodiment, the cross section area of the boss is gradually increased from top to bottom, and the outer side surface of the boss is in the shape of an arc which is concave inwards.
In the biological filter of the embodiment, sewage is slowly injected into the tank body 1 through the water inlet pipe 5, the sewage firstly slowly enters the water distribution plate 2, due to the groove design of the water distribution plate 2, the sewage enters the bottom of the water distribution plate 2, and because the edge of the water falling hole 3 on the water distribution plate 2 is higher than the bottom surface of the groove of the water distribution plate 2, the sewage stays in the water distribution plate 2, and the liquid level slowly rises, when the liquid level is higher than the edge of the water falling hole 3, the sewage enters the water falling hole 3 and flows down along the water falling hole 3, enters the filter material layer 6, after being filtered and reacted by the filter material layer 6, the sewage flows down from the through hole of the bearing layer 7, enters the bottom of the tank body 1.
When sewage passes through water distribution plate 2, because the solid pollutant that needs the filtration in the sewage, certain volume has, so partial solid pollutant is blocked by 3 edges of the hole of falling into the water, and because the velocity of water is slow, the boss outside is the inside sunken arc surface, so solid pollutant easily gathers in arc surface department, is difficult for being washed into the hole of falling into the water 3 by rivers, simultaneously because 3 edges of the hole of falling into the water are equipped with serrated plate 9, sewage flows into the hole of falling into the water from the sawtooth bottom, serrated plate can strengthen the effect of blockking to solid pollutant. When the pollutants on the surface of the water distribution plate are gathered to a certain amount, the water distribution plate 2 is taken down for cleaning, and the pollutants are gathered on the surface of the water distribution plate 2, so that the cleaning is convenient.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
