Exhaust gas contains a large amount of harmful substances and malodorous substances, such as hydrogen sulfide, sulfide, ammonia, methane, nitrogen compounds, etc. Direct discharge will cause serious pollution to the environment and emit malodor.

[0003] The existing odor treatment is to use a biological deodorization device for deodorization, including a deodorization box and a biological filler area located inside the deodorization box, and an independent tower for alkali washing is also required to be connected to the outside. The alkali washing tower and the odor treatment device are connected by an air duct, and the deodorization box is connected to water and nutrient solution to spray the biological filler area.

Then, the odor after the second treatment is introduced into the interior of the biodegradation chamber 13, and water is sprayed from the humidifying water distributor 7 to humidify the biological filler on the surface of the carrier plate 81 so that it can reach a humidity relative to the survival of the bacteria. When the odor after the second treatment passes through the tertiary filler area 8, the biological filler can be used to deodorize the odor, thereby completely degrading the odorous components in the odor, and the carrier plates 81 with arc plates staggered are used.
