The operation of the present invention will be explained with reference to the drawings showing one embodiment. Raw water 1 containing volatile organic chlorine compounds such as trichlorethylene and tetrachlorethylene is fed to a stripping device 2.
Volatile organic chlorine compounds in the water are removed by a stripping gas (such as air) 5 which is guided by the water and sprayed from above onto the filling 3 and blown from below by a blower 4, and flows out as treated water 6. do.
On the other hand, the exhaust gas 7 exhausted from the stripping device 2 contains volatile organic chlorine compounds expelled from the water, and when this exhaust gas 7 is introduced into the ultraviolet irradiation device 8 and irradiated with ultraviolet rays, a strong The volatile organic chlorine compounds are decomposed by ultraviolet energy and are discharged as a harmless treated gas 9, thereby preventing environmental pollution.
