[0002] Sewage refers to polluted water that cannot be used directly and needs to be treated. Polluted water contains a large amount of organic matter and debris. In hot weather, the organic matter in the sewage will react and produce odor, which will pollute the surrounding air. The odor of sewage is mostly stink, and the odor of sewage needs to be deodorized to prevent the odor emitted by the sewage from causing harm to the surrounding residents and employees of the sewage treatment plant.

[0003] Deodorization of sewage is an indispensable treatment method. Before deodorizing sewage, the debris in the sewage needs to be processed. These debris will affect the sewage treatment effect of the equipment, and the debris may also cause blockage of the pipeline, reducing the efficiency of sewage treatment.

[0025] There are two bubble stones 4, which are arranged up and down on the outside of the air inlet pipe 3; the diameter of the circular hole 12 on the outside of the small barrel 11 is larger than the diameter of the circular hole 12 on the outside of the large barrel 10; the end of the connecting pipe 13 away from the processing chamber 1 is fixedly connected to the gas chamber 14; the number of activated carbon layers 25 is three.

[0026] Working process: the device is installed in a sewage treatment plant, and an external power supply provides power to the electrical equipment of the device. The sewage enters the interior of the treatment chamber 1 through the water inlet pipe 6. The outlet of the water inlet pipe 6 is located above the small barrel 11, and the sewage will flow directly into the small barrel 11. The circular holes 12 are distributed on the outside of the small barrel 11. The sewage flows out from the circular holes 12, and some larger debris will be left in the small barrel 11. The sewage flowing out of the small barrel 11 enters the large barrel 10 for re-filtration, and finally flows into the filter barrel 8.
