Raw water containing volatile organic chlorine compounds such as trichlorethylene and tetrachlorethylene is led from a raw water inlet pipe and sprayed on the diffusion layer, and then a stripping gas ( Volatile organic chlorine compounds in the raw water are removed by countercurrent contact with air (e.g., air), and the raw water is turned into harmless treated water that flows out from the lower treated water outflow pipe. On the other hand, the stripping exhaust gas exhausted from the diffusion layer contains volatile organic chlorine compounds expelled from the water. Chlorine compounds are adsorbed and removed, and the treated gas becomes harmless and is discharged from the gas exhaust pipe, causing no environmental pollution.
