초록

The odor substances generated in a feed manufactory operating for the commercialization of animal-vegetablematerials were analyzed and the odor reduction efficiency by a chemical scrubber was evaluated. The majorcausative substances in the feed manufactory comprised about 45.4% of ketone compounds and about 13.3% ofaldehyde compounds. On the other hand, the removal efficiencies of diacetyl and acetoin as ketone compoundswere 77.3% and 78.1%, respectively, by a chemical scrubber. Additionally, the removal efficiencies ofacetaldehyde, butyraldehyde, valeraldehyde, 2-furancarboxaldehyde, and nonanal were 86.0%, 78.9%, 67.4%,52.8%, and 71.9%, respectively. These rates were higher than the odor generation substance contribution rate asa result of treating the exhaust gas generated from the feed manufactory by the chemical scrubber using 5% ofC3. It was also found that xylene, methylcyclopentane, benzene, ethylbenzene, 1,3,5-trimethylbenzene, and decanewere almost not removed.
