An odor prevention facility was installed and operated in a sewage treatment plant in Sejong City to reduce the odors generated during sewage and food waste treatment. High concentrations of odor were generated in the sludge treatment and solidification facilities in the sewage treatment plant. There was a limit to the deodorization treatment of odor prevention facilities.
In the sewage treatment plant, 22 kinds of compound odors and designated odorous substances were measured. Designated odor substance concentrations were measured by liquid and gas chromatography. Trimethylamine, hydrogen sulfide, aldehyde and the like were measured and analyzed. Odor intake and outlet odor were measured and analyzed. The problem was confirmed by a high concentration of odor in the sludge treatment facility and a duct installation and airtight structure, which are odor collection facilities, were improved in the treatment process. After analyzing the results, the existing biofilter in the odor prevention facility was removed since it didn’t have any deodorizing effect. The demister, chemical cleaning facility, and activated carbon adsorption process had deodorizing effects. It was found that the chemical cleaning facility was suitable for neutralizing and oxidizing 98% of complex odor and 99% of designated odor after improvement.
