step6, odor is removed after the odor is adsorbed by the gas-liquid contact layer (39) and the microbial filler layer (38), and the odor is exhausted from the exhaust pipe (34) to finish the odor treatment.

7. The method for disposing restaurant garbage odor treatment system according to claim 6, wherein the microorganism loading method comprises the following steps:

step1, preparing a microbial nutrient solution, and adding elastic fiber ball (383) filler into the microbial nutrient solution;

step2, adding 0.25g/L thioether, 0.25g/L mercaptan, 0.25g/L isoprene and 0.25g/L prenyl alcohol into the microbial nutrient solution, and intermittently introducing sulfur-containing gas into the microbial nutrient solution;

step3, culturing for 24-48 h at 28 ℃, discharging the microbial nutrient solution, and transferring the elastic fiber balls (383) into the nutrient solution prepared according to Step1 and Step 2;

and Step4, spreading a biological film on the surface of the elastic fiber ball (383), and finishing the load of the microorganisms on the elastic fiber ball (383).
