Abstract

Objectives: This study evaluated the odor emission characteristics from a sewage treatment plant near an industrial complex area in Daegu City. Methods: Odor samples were collected from March 2017 to December 2017 and analyzed for specified offensive odor substances. The odor quotient and the odor contribution were calculated. Results: Ammonia, methyl mercaptane, hydrogen sulfide, dimethyl sulfide, acetaldehyde, propionylaldehyde, toluene, xylene, and methylethylketone were detected in all samples for monitoring the specified odor compounds. The result of contribution analysis is that hydrogen sulfide made the highest contribution in all processes, followed by acetaldehyde. Conclusion: The major components of odor can be determined by evaluating their degree of contribution to the odor intensity and the concentration of the individual odor component. To increase the effectiveness of odor reduction, rather than addressing high-concentration odor compounds, policies focused on materials with a high odor contribution are necessary.
