Problems solved by technology

[0003] During the use of the current moving bed biochemical reactor, it usually directly aerates the sewage in the sewage tank through multiple sets of aeration pipes, but the aeration effect on the sewage is very limited, and it is impossible to aerate the sewage at the same time. Promote the flow of sewage and further improve the aeration effect of the device on sewage; and the current moving bed biochemical reactor often only allows the filler to float on the surface of the sewage, and cannot allow it to have sufficient sinking space and cannot allow the filler to fully Contact with sewage, thus affecting biological activity and treatment effect; at the same time, the current moving bed biochemical reactor cannot effectively perform secondary aeration treatment on sewage, which will not only make the aeration effect of sewage very limited, but also cannot improve the activity of sewage; Moreover, when the current moving bed biochemical reactor discharges sewage from the aeration tank, the filler in the aeration tank often blocks the filter screen inside the drain outlet, affecting the normal discharge of sewage, thereby affecting the entire moving bed biochemical reactor. Effect and efficiency of sewage treatment

Embodiment 1

[0039] Example 1, as Figure 1-5 As shown in the figure, when the sewage needs to be aerated, the amount of sewage inside the biological reaction tank 2 covers the top of the third guide plate 17, the filler is poured onto the surface of the two sets of third guide plates 17, and the external The control panel controls the aeration device 1 to deliver the gas to the inside of the collecting bin 3, and the collecting bin 3 is transported to the inside of the aeration branch pipe 14 and the rotating pipe 101 respectively, and the gas inside the rotating pipe 101 passes through the eight groups of U-shaped pipes 102. The first aeration head 103 is ejected, and the generated thrust pushes the eight groups of U-shaped pipes 102 to rotate with the rotating pipe 101 as the axis, which also makes the two groups of rotating pipes 101 rotate oppositely, and promote the flow of sewage during the rotation process. The water outlet 18 ejects the sewage at an inclined angle, so that the sew...

Embodiment 2

[0040] Example 2, as Figure 1-7 As shown, after the sewage aeration in the biological reaction tank 2 is completed, when the sewage flows into the spiral drainage groove 403 through the drain pipe 121, the sewage pushes the fan blade 123 to drive the rotating shaft 122 to rotate, so that the installation bar 124 on the rotating shaft 122 follows the Rotate, use the brush 126 on the inside of the mounting bar 124 to rotate and scrape the outside of the filter screen 125, and scrape off the packing blocking the outside of the filter screen 125; the sewage entering the spiral drainage groove 403 follows the spiral drainage groove. 403, during the process, the secondary aeration is performed on the sewage flowing through the spiral drainage tank 403 through the auxiliary aeration holes 405 on the installation pipe 404, and then the sewage is collected at the inner bottom of the connection tank 8, and finally passes through The water pump 5 pumps the sewage at the top of the conne...

Abstract

The invention discloses a moving bed biochemical reactor which comprises a biological reaction tank, a sedimentation tank and a connecting tank, an aeration device is mounted at the bottom of one end, far away from the connecting tank, of the biological reaction tank, a collection bin is mounted at the bottom of one end of the biological reaction tank, and the output end of the aeration device is communicated with the interior of the collection bin; and third guide plates are symmetrically mounted on the two sides of the two ends in the biological reaction tank, and first guide plates are symmetrically mounted at the middle positions of the two ends in the biological reaction tank. Through cooperative use of the first guide plate, the second aeration head, the second guide plate and the third guide plate, sewage on the upper layer gradually flows towards the two inner sides of the biological reaction tank, flows downwards from the two inner sides of the biological reaction tank, and then passes through the space between the first guide plate and the third guide plate again to form circular flow of the sewage; and the conversion treatment effect of bacteria on the filler on ammonia nitrogen in the sewage is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a moving bed biochemical reactor. Background technique [0002] Moving bed biochemical reactor is another innovative biofilm reactor that has been paid much attention by researchers in recent years. The clogging of the pool is developed by the complicated operation of cleaning the filter material and replacing the aerator. [0003] In the process of using the current moving bed biochemical reactor, the sewage in the sewage tank is usually aerated directly through multiple groups of aeration pipes, but the aeration effect of the sewage is very limited, and it is impossible to aerate the sewage at the same time. Promote the flow of sewage to further improve the aeration effect of the device on sewage; and the current moving bed biochemical reactor often only allows the filler to float on the surface of the sewage, which cannot allow it to have sufficient sinking space, an...
