Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an air volume control device based on MBBR technology. Background Technology

[0002] MBBR is a novel water treatment process that integrates traditional fluidized bed and contact oxidation. By adding a certain amount of packing material with a density slightly less than that of water to the reaction tank, microorganisms that degrade pollutants attach and grow on the surface of the packing material, forming a microbial film of a certain thickness. Through aeration or stirring, the suspended carrier is fluidized, thereby achieving the effect of pollutant removal.

Dissolved oxygen meter 28 transmits dissolved oxygen concentration data in aeration tank frame 1 to control device 21. Control device 21 starts the corresponding number of blowers 16 according to actual needs. Blower 16 blows oxygen into aeration tank frame 1 through channel 11, so that dissolved oxygen in aeration tank frame 1 reaches a suitable concentration, avoids excessive aeration and reduces carbon source dosage, and at the same time ensures stable effluent quality and energy saving, solving the problems of unstable ammonia nitrogen removal and low total nitrogen removal rate.

[0028] The aeration component 2 can inject the corresponding oxygen into the aeration tank frame 1 according to actual needs, while facilitating the connection of multiple blower devices 16 to the aeration tank frame 1 by the staff, thereby solving the problems of unstable ammonia nitrogen removal and low total nitrogen removal rate, thus increasing the aeration effect of the air volume control device.

[0029] Reference Figure 3 In this embodiment, a T-shaped plate 12 is fixedly installed on one side of the baffle 7, and a square ring plate 13 is slidably installed in the limiting groove 6.

[0030] A clamping plate 14 is slidably installed on one side of the square ring plate 13, and a spring 15 is fixedly installed between the clamping plates 14.

[0032] The annular sealing gasket 20 can increase the sealing between the square ring plate 13 and the fixed plate 4, thereby improving the stability of the air volume control device during use.

[0033] Reference Figure 2The monitoring component 3 in this embodiment includes a guide plate 22, a top plate 23, a square plate 24, a threaded column 25, a turntable 26, a second buckle 27, and a dissolved oxygen meter 28.

The top plate 23 is fixedly installed on the top of the guide plate 22. The turntable 26 needs to be rotated to drive the threaded column 25 to rotate. The threaded column 25 drives the dissolved oxygen meter 28 to move through the square plate 24.

[0034] The monitoring component 3 allows staff to easily adjust the position of the dissolved oxygen meter 28 according to actual needs, thereby improving the flexibility of the air volume control device in use.

[0035] The square plate 24 is slidably installed in the square groove 29. The threaded column 25 is rotatably installed between the top plate 23 and the aeration tank frame 1.

The second buckle 27 is fixedly installed on the top of the top plate 23. The dissolved oxygen meter 28 is set on one side of the square plate 24.

[0036] Working principle: First, rotate the turntable 26 according to actual needs to drive the threaded column 25 to rotate. The threaded column 25 drives the dissolved oxygen meter 28 to move through the square plate 24. After the dissolved oxygen meter 28 is adjusted, use the second buckle 27 to limit and fix the turntable 26. Use the hand-held blower 16 to insert the square ring plate 13 into the limiting groove 6. The guide block 18 guides and squeezes the clamping plate 14, so that the clamping plate 14 is engaged with the T-shaped plate 12. The square ring plate 13 drives the baffle 7 to move through the clamping plate 14, so that the square ring plate 13 corresponds with the annular sealing gasket 20. When the square ring plate 13 and the annular sealing gasket 20 are engaged... After the annular sealing gasket 20 is completed, the first buckle 17 is used to limit and fix the square ring plate 13. The dissolved oxygen meter 28 transmits the dissolved oxygen concentration data in the aeration tank frame 1 to the control device 21. The control device 21 starts the corresponding number of blowers 16 according to actual needs. The blowers 16 blow oxygen into the aeration tank frame 1 through the channel 11, so that the dissolved oxygen in the aeration tank frame 1 reaches a suitable concentration, avoiding excessive aeration and reducing the amount of carbon source added. At the same time, it ensures that the effluent is stable and meets the standards, and saves energy and reduces consumption, thus solving the problems of unstable ammonia nitrogen removal and low total nitrogen removal rate.
