<p>PROBLEM TO BE SOLVED: To upgrade the deodorizing capability by prolonging contact time between a treatment liquid and odorous air bubbles. SOLUTION: In the deodorizing device for mixing an odor in the form of air bubbles with the treatment liquid W, a liquid feed pipe 13 for guiding the treatment liquid W, an air bubble inclusion element 14 installed on the upstream side of the liquid feed pipe 13, an odor supply pipe 16 joined to the element 14 and a gyrating element 17 which is installed halfway through the liquid feed pipe 13 and makes the treatment liquid W flowing in the liquid feed pipe 13 gyrate, are provided. The contact time between the treatment liquid W and the air bubbles is prolonged by flowing the treatment liquid W including the air bubbles through the liquid feed pipe 13 so that the treatment liquid W gyrates in a state where it is continuously full without separating the odorous air bubbles from the treatment liquid W. Thus, it is possible to upgrade the deodorizing capability.</p> |
