る。In this ozone treatment, ozonized air with an ozone concentration of 20 g ozone/N m'-air is generally used because of the operating efficiency of the ozone generator. From the ozone reaction tank in which ozonized air and water to be treated are mixed into a gas-liquid state, surplus ozonized air resulting from the ozone reaction is discharged as waste ozone scum.

できず、オゾン分解処理か不可欠のものとなっている。The concentration of waste ozone scum depends on the water to be treated, the purpose of the ozone reaction,
It varies depending on the ozone concentration of the ozonized air and the injection rate of the ozonated air, and the ozone injection rate of several mg ozone/e of water often results in an exhaust ozone concentration exceeding 10C1010Cl0pp/VOi. This concentration is 0.1 ppm, which is the permissible concentration for industrial hygiene in the Ministry of Health and Welfare's ozone equipment guidelines.
It is much higher than that, and it cannot be brought to life in its current state, so ozone decomposition treatment is indispensable.

か確認されている。(Problem to be solved by the invention) However, it is difficult to use a mankan-based exhaust ozone decomposition catalyst in a cracking tower (
When υ1 ozone is processed with an ozone concentration of 11,000pp in the ozonized air filled in the catalyst tower and introduced into the decomposition tower,
Although it varies depending on the processing conditions, after a certain period of time, the ozone decomposition rate no longer reaches 100%, and the ozone concentration of the processing gas decreases to 0.1%. It will not drop below ppm. This phenomenon is said to be due to a temporary decrease in the performance of the ozone decomposition catalyst, and then the performance recovers again and the decomposition rate decreases to 1 D C) 06
It is the ozone concentration of the treated waste that satisfies the condition (11,
below lppm. It has been confirmed that there is a periodicity in this fluctuation trend of the decomposition rate.

。(Function) The present invention connects a catalyst tower filled with an exhaust ozone decomposition catalyst and an activated carbon tower filled with activated carbon on the downstream side of the catalyst tower outlet.

入った後、活性炭を通過する。排オゾン分解触媒の処理
性能か良好な時は、排オゾンガス中の殆んとのオゾンか
触媒塔で処理され、許容濃度０．ｌｐｐｍ以下になる。After entering the catalyst tower with an ozone concentration of about 1000 ppm, the exhausted ozone scum passes through activated carbon. When the treatment performance of the exhaust ozone decomposition catalyst is good, most of the ozone in the exhaust ozone gas is treated in the catalyst tower, and the permissible concentration is 0. below lppm.
従って、次の活性炭塔では、処理するオゾン濃度か０．
ｌｐｐｍ以ドと低いた於、殆んと無負荷の状態で通過す
るので、活性炭の消耗は殆んど無い。Therefore, in the next activated carbon tower, the ozone concentration to be treated is 0.
The activated carbon is hardly consumed because it passes under almost no load since it is less than lppm.

になった触媒塔から排出されるガスを、許容濃度以下に
活性炭塔で処理することかできる。As described above, when the treatment performance of the catalyst tower is good, most of the ozone is treated in the catalyst tower, so even if it passes through the activated carbon tower, there is almost no ozone, and activated carbon is not used for treatment. However, if the treatment performance of the catalyst tower deteriorates, the gas discharged from the catalyst tower whose concentration has exceeded the allowable concentration can be treated with an activated carbon tower to reduce the concentration to below the allowable concentration.
」二記作用は、触媒層と活性炭層とを積層して一体化し
た分解塔でも同様である。The same effect can be obtained in a cracking tower in which a catalyst layer and an activated carbon layer are laminated and integrated.

殆んとない。When the treatment performance of the ozone decomposition catalyst 6 is good, most of the ozone in the exhaust ozone gas is treated by the catalyst tower and the concentration becomes below the permissible concentration of 0.1 ppm LI. Therefore, the activated carbon tower is in an unloaded state and is not used for processing, so there is almost no consumption of activated carbon.

Ozone concentration 101000pp Humidity 9 C1
%) was aerated at 1 e/min, and the ozone concentration at the outlet of the activated carbon tower was measured. By installing the activated carbon tower after the catalyst tower, it was confirmed that the ozone concentration of the treated gas remained below the permissible concentration of 0 lppm even after long-term lj+ozone treatment, and it was confirmed that the treatment was in good condition. Also, the amount of charged activated carbon is
1/2 to 1/10 (50 to] Q c of the filling amount of the catalyst column
Even on the scale of c), the concentration of ozone entering the activated carbon tower was low and the load was low, so the treatment life was long and no breakthrough was confirmed. In other words, since the activated carbon tower of this device is small or used for low-concentration finishing, the shortcoming of activated carbon, which is its longevity, is not an issue.
第３図は本発明の他の実施例を示す構成図である。FIG. 3 is a block diagram showing another embodiment of the present invention.
