摘要： PURPOSE: To enhance ozone treatment capacity by eliminating the short-circuit flow of water to be treated reaching a bottom part communication port on the outflow side of a contact tank from the weir on the inflow side thereof. CONSTITUTION: Water to be treated flows in a contact tank 4a from the weir 3 on the inflow side thereof and flows out of the bottom part communication port 10 on the outflow side thereof. Ozone diffusion cylinders 5 are arranged on the bottom part of the contact tank 4a so as to go a little toward the outflow side of the contact tank 4a as a whole. Water streams falling on the inflow side and rising on the outflow side are formed in the contact tank 4a by ozonized gas diffused from the ozone diffusion cylinders 5. Therefore, the short-circuit flow from the weir 3 to the bottom part communication port 10 is prevented.

摘要： PURPOSE:To keep catalytic treatment capacity over a long period of time by arranging a pretreatment tower on the upstream side of a catalyst tower to pack the same with an adsorbent adsorbing the component bonded to a catalyst and washing the same with hot water when a definite amount of the adsorbed and bonded component on the catalyst is accumulated. CONSTITUTION:Exhaust ozone gas enters a collector 4 from piping 5 and, after a part of the waterdrops in the exhaust ozone gas is collected, said gas passes through a pretreatment tower 9 from piping 3 through a solenoid valve 10. At this time, the component bonded to a catalyst is adsorbed by the adsorbent 8 received in the pretreatment tower 9 and, thereafter, the exhaust ozone gas enters a catalyst tower 2 through a solenoid valve 7 and the ozone gas is separated by the catalyst 1 in the tower 2. When treatment is performed for a definite time, the component bonded to the catalyst is accumulated on the adsorbent 8 and, therefore, the solenoid valves 7, 10 are closed at every definite time and a solenoid valve 14 is opened to supply the hot water heated by a heater 11 to the pretreatment tower 9 by a pump 13. The adsorbed substance is dissolved and separated from the adsorbent 8 and, thereafter, a solenoid valve 15 is opened to drain the dissolved and separated substance. After the washing of the adsorbent is completed, the regular treatment of exhaust gas is again performed.
