Abstract

PURPOSE: To prevent pollution and intend to use ozone completely, by returning the waste gas containing unreacted ozone discharged from the contact layer, when re-using treated water, to the aeration tank for use.
CONSTITUTION: When water after secondary treatment in a sewage treatment plant is re-used as miscellaneous use water after tertiary treatment, in the treating process from waste water intake part 1 to sedimentation pond 2, aeration tank 3, sedimentation pond 4, sand filtering pond 5, ozone contact tank 6 and storage tank 7, ozone is suppliesd into the contact tank 6 from a suply source 8, and waste gas containing unreacted ozone by 10 to 30% with respect to the charge volume is injected into the aeration tank 3 by a blower 9. Or, an ejeactor may be used for injection. The ozone instantly reacts with chromatic components, detergent, COD, etc. in the waste water and is completely consumed, so that no pollution is made.
