In the implementation of the invention, the centrifugal fan 16 sucks waste gas of the sewage station into the machine body 13 from the air inlet pipe 17, and when the waste gas passes through the first fan cover 18, the first motor 20 drives the first motor shaft 21 to rotate, and the first motor shaft 21 drives the first fan blades 22 to rotate, so that the waste gas is uniformly blown into the machine body 13. The first liquid pump 26 pumps the spray liquid in the liquid supply cavity 23 into the first liquid pump tube 27, and then conveys the spray liquid into the liquid outlet tube 29. The spray liquid is sprayed out from the spiral nozzle 30 in a mist form, impurities, partial organic matters and acid gases in the waste gas are removed through the spray effect, and the waste gas is humidified at the same time so as to be beneficial to subsequent biological purification treatment.

The first partition plate 42, the second partition plate 43 and the third partition plate 44 block the spray liquid, so that microorganisms in the first biological filler layer 45 can sufficiently purify the spray liquid. The purified spray liquid is discharged from the liquid discharge pipe 46. The pretreated waste gas is sucked into the air inlet cavity 6 by the first exhaust fan 5, then is conveyed to the air outlet cavity 8 from the first air outlet pipe 7, and finally is discharged from the air outlet hole 9. The second motor 49 drives the second motor shaft 50 to rotate, the second motor shaft 50 drives the first flywheel 51 to rotate, the first flywheel 51 drives the second flywheel 53 to rotate by using the first transmission belt 55, the first rotating shaft 52 drives the third flywheel 54 to rotate, and the third flywheel 54 drives the fourth flywheel 58 to rotate by using the second transmission belt 59. The fourth flywheel 58 drives the first fixing sleeve 60 to rotate by using the second rotating shaft 57, so as to drive the second fan blade 61 to rotate, generate ascending wind force, and blow the exhaust gas discharged from the air outlet hole 9 upwards. When the exhaust gas passes through the second bio-filler layer 67, the exhaust gas is firstly physically adsorbed by the activated carbon layer 68, and then adsorbed by the biofilm formed by microorganisms on the first filler pipe 69. The exhaust gas continues to rise and passes through the third bio-filler layer 70, and is degraded by the bio-film formed by the microorganisms grown on the second filler pipe 71, decomposing odor substances and toxic pollutants. The wind power generated in the process of rising the waste gas drives the third fan blade 75 to rotate, and the third fan blade 75 drives the second fixing sleeve 74 to rotate, so that the cooperation of the third driving belt 73 and the fifth flywheel 72 is utilized to drive the second filling pipe 71 to rotate, and the biomembrane on the surface of the second filling pipe 71 can be fully contacted with the waste gas, so that the waste gas is degraded better. The treated nontoxic and odorless gas enters the gas collecting hood 10, the gas is conveyed into the chimney 4 from the second gas outlet pipe 11 by the second exhaust fan 12, and finally the gas is discharged from the upper part of the chimney 4 to finish high-altitude discharge.
The fixing door 66 is opened, the second bio-filler layer 67 and the third bio-filler layer 70 are placed on the first supporting block 77 and the second supporting block 65, and then the height of the second supporting block 65 is adjusted on the slideway 63, so that the second supporting block 65 compresses the second bio-filler layer 67 or the third bio-filler layer 70 and is fixed by using the fixing bolt, the fixing door 66 is closed, and the inner side of the fixing door 66 is attached to the right side of the second bio-filler layer 67 or the third bio-filler layer 70, so that the second bio-filler layer 67 or the third bio-filler layer 70 is fixed.
