PURPOSE:To make a bacteria-reduced discharge gas harmless effectively by performing decompressed discharge, normal pressure, and again decompressed discharge repetitively, and introducing the bacteria-reduced discharge gas to a gas adsorbing device. CONSTITUTION:The bacteria-reduced discharge gas which is first taken out of a gas bacteria reducing apparatus 1 after bacteria reducing process and which still contains a high concentration of detrimental components, is introduced to a combustion furnace 7 to undergo a process for turning harmless. Decompressed discharge, normal pressure, and again decompressed discharge are repeated in several cycles so as to expel the residual discharge gas from the gas bacteria reducing apparatus 1, and the bacteria-reduced discharge gases of the second takeout and thereafter containing a low concentration of detrimental components are introduced to gas adsorbing apparatus 9A, 9B with changing- over of selector valves V1-V4 to be turned harmless. |
