Sludge slurry after spray washing or back washing is rotated by a deodorization rotary disc 1-7 and falls onto a liquid collection inclined plate 1-16 by gravity, and finally is discharged into an aeration tank through a liquid outlet 1-15, and a small amount of malodorous substances which are not completely reacted in the slurry can be thoroughly degraded by a large amount of activated sludge strains in the aeration tank.
During the operation of the device, the automatic control system carries out real-time monitoring, analysis and feedback on parameters such as the amount of waste gas at the inlet and the outlet of the deodorization tower, the concentration of the waste gas, the temperature, the content of suspended matters in slurry, the reduction of the filler layer and the like, and carries out automatic regulation and control on the concentration of spraying slurry, the backwashing frequency, the rotating speed of a motor and the like so as to achieve the optimal operation working condition, and the whole deodorization process and the system are organically combined to realize the accurate control on the operation process.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
