<p>PROBLEM TO BE SOLVED: To efficiently deodorize domestic sewage with ozone gas. SOLUTION: In a water washing tower 1, a water storage part 2, a gas mixing part 3 which introduces odor gases, an air-liquid counter current contact part 4 where a large number of corrugated plates, for which L-shaped bent parts are connected in the vertical direction, are arranged, a water discharging part 5 which makes the water pumped up from the water storage part naturally stream down, a demister 6 having a structure which is the same as the air-liquid counter current contact part, and a discharge port 7 which communicates with a discharge path 23, are provided in order, and ozone gas is fed to the water storage part, and the ozone gas is discharged to the gas mixing part by bubbling, and the water in the water storage part is made ozone water, and the ozone water which streams down from the water discharging part is made to stream down respective bent parts of the air-liquid counter current contact part, and in the meantime, the mixed gas is deodorized while rising in the intervals of the air-liquid counter current contact part, and the discharged gas which has passed the demister contains moisture only, and after the moisture is removed by a compression heat of a blower 10 which is provided on the discharge path, the discharged gas is fed to a gas purifying part which is filled with an ozone gas removing material 24.</p> |
