When the biological aerated filter normally works, sufficient oxygen can be provided for aerobic microorganisms attached to the filter material through the aeration pipe, so that the aerobic microorganisms can be greatly propagated to improve the nitrification efficiency of the biological aerated filter. However, after the filter tank is operated for a certain time, due to the strong interception function of the filter material, a large amount of suspended matters in the sewage can be adhered to the surface of the filter material, and meanwhile, the biological membrane on the surface of the filter material can also grow and thicken, so that the growth of microorganisms can be inhibited to a certain extent, and the working efficiency of the filter tank is influenced. Therefore, the filter chamber needs to be backwashed at regular intervals, suspended matters intercepted in the filter material and the aged and fallen biological membrane are discharged out of the filter chamber along with the backwashed water, and the normal operation of the biological filter chamber is recovered.
Suspended matters and aged and fallen biological membranes in the filter tank are discharged out of the filter tank through backwashing water, so that whether backwashing water at all parts of the filter tank can be uniformly discharged or not is greatly significant for thoroughly removing the suspended matters and the aged biological membranes and maintaining stable and efficient operation of the biological filter tank. The bottom of the existing sand washing drainage tank is welded by flat-bottom steel plates, when the aeration of the filter tank is uneven, the bottom of the water outlet tank bears the large impact force of water flow, the water outlet tank is often deformed by impact, and the sand washing drainage tank is particularly obvious when being used in a circular biological filter tank. Meanwhile, the back washing water of the filter tank flows back into the filter tank after impacting the bottom of the water outlet weir, so that the sewage is repeatedly swirled and is difficult to discharge quickly and smoothly, and the back washing efficiency of the filter tank is also influenced to a certain extent.
SUMMERY OF THE UTILITY MODEL
On the one hand, the utility model discloses embodiment provides a sand washing water drainage tank, at a plurality of grooves of main tank bilateral symmetry arrangement, collects each position of discharge filter and comes water, reduces the direct impact force of back flush rivers, and extension play basin life reduces the rivers disturbance simultaneously, makes the smooth discharge of back flush water.
The sand washing drainage tank comprises a main tank and a plurality of branch tanks which are communicated with the main tank and are uniformly distributed along the length direction of the main tank at intervals, wherein the branch tanks are perpendicular to the main tank and are symmetrically distributed on two sides of the main tank, and the cross sections of the main tank and the branch tanks are of U-shaped structures.
Preferably, the bottom of the branch groove is higher than the bottom of the main groove.
Preferably, the number of the branch grooves is an even number which is not less than eight.
Preferably, a plurality of through-going splitter boxes are arranged between the branch grooves to form a flow channel for communicating the branch grooves and the main groove.
On the other hand, the biological aerated filter provided with the sand washing drainage tank is also provided.
Preferably, the biological aerated filter is of a cylindrical structure, the main tank of the sand washing and water draining tank is radially arranged along the cross section of the tank body, and the branch tanks are perpendicular to the main tank and symmetrically and uniformly distributed on two sides of the main tank.
The utility model relates to a beneficial effect of embodiment:
(1) the branch grooves symmetrically arranged on the two sides of the main groove can collect water from all parts of the filter chamber to the main groove in a shunting manner, the water flow directions of the opposite group of branch grooves are opposite, and the main groove and the branch grooves are of U-shaped structures in cross sections, so that the direct impact force of the backwashing water flow can be effectively buffered when the backwashing water enters the main groove, and the service life of a pipeline is prolonged.
(2) The branch grooves are uniformly distributed along the length direction of the main groove at intervals, so that the water coming from all parts of the filter pool is uniformly converged into a stream, the disturbance of water flow can be reduced on the whole, and the back washing water is smoothly discharged.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
The sand washing drainage channel shown in fig. 1-3 comprises a main channel 1 and a plurality of branch channels 2 communicated with the main channel. The branch grooves 2 are perpendicular to the main groove 1 and symmetrically distributed on two sides of the main groove 1, the branch grooves 2 are evenly distributed at intervals along the length direction of the main groove 1, and the cross sections of the main groove 1 and all the branch grooves 2 are of U-shaped structures. The branch grooves 2 can collect water from all parts of the filter tank into the main groove 1, and the branch grooves 2 are uniformly distributed to ensure that water flow is uniformly converged, so that water flow disturbance is reduced on the whole, and smooth discharge of backwashing water is facilitated. To achieve this effect, the number of the branch grooves 2 is preferably an even number of eight or more, and for example, in the case of eight, four branch grooves 2 are uniformly provided on both sides of the main groove 1. In addition, the sections of the main groove 1 and the branch grooves 2 are both U-shaped structures, and the water flow directions of the opposite group of branch grooves 2 are opposite, so that the direct impact force of the backwashing water flow can be effectively buffered when the backwashing water enters the main groove 1, and the service life of the pipeline is prolonged.
In this embodiment, the bottoms of the branch troughs 2 are higher than the bottom of the main trough 1, so that the water flows collected by the opposite group of branch troughs 2 do not directly converge at the outlets of the branch troughs 2, but meet in the main trough 1 after a section of fall, and the water flow disturbance can be further reduced. The plurality of the flow dividing grooves 3 which are communicated with each other can be arranged between the branch grooves 2 to form a flow passage for communicating the branch grooves 2 and the main groove 1, the flow dividing grooves 3 are preferably arranged along the length and width directions of the branch grooves 2, and when the water flow is large, particularly the water flow in partial areas is large due to uneven aeration, the flow dividing grooves 3 can well divide the water body for the second time, thereby further inhibiting the generation of rotational flow.
Based on the characteristics, the scheme is applied to the existing biological aerated filter, so that the water flow disturbance can be effectively slowed down, and the backwashing efficiency is improved. Fig. 1-3 are schematic views of the application of the solution to a cylindrical biological aerated filter, wherein the main tank 1 is radially arranged along the cross section of the tank body 4 and is communicated with a water outlet 41 of the filter, the branch tanks 2 are perpendicular to the main tank 1 and symmetrically and uniformly distributed on two sides of the main tank 1, the number of the branch tanks 2 on each side is four, and both the main tank 1 and the branch tanks 2 can be made of carbon steel with the thickness of 4 mm.
