<p>PROBLEM TO BE SOLVED: To eliminate a waste of active carbon used in a waste ozone treating device and eliminate the danger of the undecomposed waste ozone gas involved by a shortage of contact time discharging, and continuously perform waste ozone treatment. SOLUTION: A first and a second waste ozone treating tower 1, 2 are connected in series or in such a manner that waste ozone is passed through only the waste ozone treating tower on one side by switching operation of four-way switching valves 4, 5. First the waste ozone is passed through the waste ozone treating towers 1, 2 one by one, and when an incineration area 7 reaches the second waste ozone treating tower 2, by switching operation of the switching valve 4, the waste ozone is passed through only the second waste ozone treating tower 2 and active carbon in the first waste ozone treating tower 1 is replaced. And the second and the first waste ozone treating towers are connected in series, and when the incineration area 7 reaches the first waste ozone treating tower 1, the waste ozone is passed through only the first ozone treating tower 1 to replace the active carbon in the second waste ozone treating tower 2.</p> |
