<p><P>PROBLEM TO BE SOLVED: To provide a low cost deodorization treatment apparatus which efficiently carries out final deodorization treatment without using a fourth treatment vessel. <P>SOLUTION: The deodorization apparatus comprises a water jetting device 10, a first treatment vessel 2 which discharges alkali aqueous solution and water-contacted malodorous gas 14 by contacting raw malodorous gas with the spray water of the water jetting device 10, a second treatment vessel 3 which discharges acid-contacted malodorous gas 36 by contacting the water-contacted malodorous gas 14 with shower form second treating agent 27 formed of citric acid solution, a stabilized acid spray device 52 for spraying sprayed stabilized acid 53 formed of stabilized chlorine dioxide, and a third treatment vessel 4 which discharges deodorization gas 54 through the oxidation and deodorization of the malodorous gas 36 due to active oxidizing power by generating an active acid state where the stabilization of the sprayed stabilized acid 53 is lost by contacting the sprayed stabilized acid 53 with the acid-contacted malodorous gas 36. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
