[0002] Hydrogen sulfide, ammonia and other components in landfill gas have strong pungent odor, which can form unpleasant odor in landfill and its surrounding area. These odors not only affect the quality of life of the surrounding residents, leading to problems such as olfactory discomfort and breathing difficulties of residents, but also have a negative impact on the surrounding ecological environment, such as affecting the growth of nearby vegetation and the survival environment of animals. Treating these gases can eliminate odors and create a good living and ecological environment.

The garbage disposal landfill odor treatment device can make the odor fully contact and react with the neutralizing liquid, and the neutralization effect is excellent. By setting the odor treatment mechanism, the odor enters the device main body inside along the air inlet pipe while blowing the flap to rotate, and stirs the neutralizing liquid in the air inlet pipe to speed up the neutralization reaction. With subsequent odor input, the air pressure in the air inlet pipe increases to press the neutralizing liquid level in the pipe, and then the odor is discharged from the through hole, and a large number of bubbles are generated, so that the odor fully diffuses and reacts in the neutralizing liquid.
