Due to the continuous economic development and industrialization, emissions of air pollutants are continuously increasing, and the types of air pollutants are gradually diversifying. In particular, malodorous gases generated in the manure treatment plant, wastewater treatment plant and various plants include hydrogen sulfide (H ₂ S), mercaptan (R-SH), ammonia (NH ₃ ), and amines (RNH ₂ ). Inhalation usually causes headaches or discomfort.

Therefore, researches for removing malodorous gas in various aspects have been conducted, and many malodorous treatment techniques are known accordingly. Currently, odor gas treatment technologies are largely used, such as activated carbon adsorption, chemical liquid cleaning, ozone oxidation, combustion deodorization, and biological treatment methods such as soil microbial treatment, activated sludge, and biofilter. These methods are selected depending on the treatment environment to remove odor gas and may be used alone or in combination of two or more.
