The types and distribution ratio of odor removal systems installed in publicly owned environmental facilities such as sewage treatment, wastewater treatment, manure treatment, livestock manure treatment, and food waste treatment were investigated. Since the intensity of the odor and the composition of the odor substances are different depending on the type of each public treatment facility, different odor removal efficiencies were derived depending on the applied odor removal technology. In addition, the removal efficiency of complex odors and individual odor substances of odor removal systems such as those applying biofilters, scrubbers, and adsorption towers were also compared and evaluated. Although it depends on each odor removal technology and application facility, about 50% of various odor removal systems presented an odor removal performance of less than 30%. The odor removal systems with an odor removal efficiency of 70% or more were evaluated to be less than 30% of the total number. Therefore, we suggest that odor removal efficiencies should be improved through continuous monitoring, diagnosis, reinforcement of maintenance, and improvement of systems.
