Abstract

<p>At high humidity, odor diffuses from wastewater storage tanks installed outdoors. Deodorization performance could be decreased for water vapor adsorbed to the activated carbon. This study attempted to reduce the amount of water vapor adsorption to the activated carbon by using an electric heater. Hydrogen sulfide, the main odorous substance emitted from wastewater storage tanks installed outdoors at a business site in the Kanto region, was treated by activated carbon with electric heater. When the temperature rise was set to 5° C, the concentration of hydrogen sulfide after passing through activated carbon was 0.7 ppm or less while it exceeded 10 ppm before passing through the activated carbon. This confirms that the required deodorizing performance was obtained.</p>
