となるところから、吸着剤によって排ガスを吸着処理し
、無害化することが一般的に考えられる。These volatile organic chlorine compounds contained in water can be easily removed from the water by stripping, but the volatile organic chlorine compounds migrate into the exhaust gas exhausted during stripping, and this exhaust gas is If released into the atmosphere untreated, it may cause new environmental pollution, so it is generally considered that exhaust gases are adsorbed and treated with an adsorbent to render them harmless.

雑であり、全体のランニングコストも高くなる点が問題
であった。However, although the above-mentioned adsorption treatment of exhaust gas is a relatively reliable method, since the concentration of the target component is generally extremely low, below several tens of cm/Nm', the adsorption capacity is limited to several percent (WT
), and it is also necessary to treat the desorbed components in the used regenerant discharged during regeneration, which makes the treatment operation complicated and increases the overall running cost.

Using an adsorbent, the exhaust gas discharged from water stripping containing volatile organic chlorine compounds can be detoxified easily and at low cost, and the harmful components that are desorbed and emitted when the adsorbent is regenerated can also be rationally treated. The purpose of the present invention is to provide a method that can remove these substances and thereby prevent environmental pollution.

The adsorbent in the adsorption tower is regenerated with a regeneration gas to desorb the adsorbed components, and the regenerated exhaust gas discharged during the regeneration is irradiated with both ultraviolet rays of germicidal radiation and ozone generation radiation to desorb the adsorbed components into the regenerated exhaust gas. The present invention provides an exhaust gas treatment method characterized in that after the volatile organic compound is decomposed, the gas is further guided to the adsorption tower and subjected to adsorption treatment.

処理ガス９となって大気中に放散される。The operation of the present invention will be described with reference to drawings showing implementation. Raw water 1 containing volatile organic chlorine compounds such as trichlorethylene and tetrachlorethylene is introduced upward into a packed column 3 by a pump 2. Volatile organic chlorine compounds in the water are removed by stripping air 5 and the like blown from below by a blower 4, and the water is discharged as treated water 6. At this time, the exhaust gas 7 exhausted from the packed tower 3 contains volatile organic chlorine compounds expelled from the water, and this exhaust gas 7 is absorbed by an adsorbent (granular, fibrous, honeycomb-like activated carbon, etc.). Volatile organic chlorine compounds in the exhaust gas 7 are adsorbed and rendered harmless by introducing the gas into an adsorption tower 8 filled with a natural or synthetic adsorbent such as zeolite or molecular sieve for adsorption treatment. The processed gas 9 is released into the atmosphere.

入して紫外線を照射する。In such an adsorption operation, the adsorbent in the adsorption tower 8 loses its adsorption capacity as adsorption progresses, and when it reaches saturation, regeneration is performed to desorb the adsorbed components. That is, for example, the stripping air 5 is branched and air heated by a heater 10 is supplied as the regeneration gas 11 to the saturated adsorption tower 8 to desorb the components adsorbed by the adsorbent. Since the regenerated exhaust gas 12 discharged at this time contains harmful components such as volatile organic chlorine compounds desorbed during the regeneration of the adsorbent, this regenerated exhaust gas 12 is introduced into the ultraviolet irradiation device 13 and irradiated with ultraviolet rays. do.

ることもできる。In the ultraviolet irradiation device 13, 253.7 nm and 18
Harmful components in the regenerated exhaust gas 12 are decomposed by irradiation with ultraviolet light having a main wavelength of 4.9 nm. In this case, 253.7n
Ultraviolet rays, which are so-called germicidal rays with a main wavelength of The decomposition effect is demonstrated. As organic substances that can be effectively decomposed, organic halogen compounds are extremely effective against ants, especially trichlorethylene and tetrachloroethylene. These ultraviolet rays may be irradiated simultaneously or separately.

再び再生法の吸着塔８に導いて、残留する未分解成分を
吸着させ、完全無害化してから大気中へ放散する。In this way, some undecomposed components remain in the regenerated exhaust gas 12' after being irradiated with ultraviolet rays, and cannot be released into the atmosphere as is. Therefore, the regenerated exhaust gas 12' after being irradiated with ultraviolet rays is again guided to the adsorption tower 8 of the regeneration method, where the remaining undecomposed components are adsorbed, completely rendered harmless, and then released into the atmosphere.

利である。In the above operation, if only one adsorption tower is used, it is necessary to interrupt the adsorption operation of the stripping exhaust gas 7 when regenerating the adsorption tower 8, but as shown in the example shown in the figure, it is necessary to interrupt the adsorption operation of the stripping exhaust gas 7. Separately, by arranging adsorption towers 8' (not only one tower but a plurality of towers) in parallel, adsorption and regeneration can be performed alternately and the treatment can be continued continuously, which is convenient.

At times, the regenerated exhaust gas 12 was regenerated with heated air, and after being irradiated with ultraviolet rays, it was treated in the other regenerated adsorption tower 8'.
