WATER TREATMENT APPARATUS

摘要

PURPOSE:To prevent scattering of harmful substances in the atmosphere in a water treatment apparatus by joining an electrical discharge path part and an exhaust treatment apparatus in which charged ozone water is sprayed from electrical spraying nozzles to an exhaust port of a closed treatment vessel. CONSTITUTION:Water to be treated which is incorporated in a closed treatment vessel 1 is aerated to treat with activated sludge. An exhaust treatment apparatus 3 provided with electrical spray nozzles 4 wherein ozone water fed from a supply tank 5 of the ozone water is charged and sprayed therefrom is joined to an exhaust port 2 of the treatment vessel 1. A discharge path part 6 is provided to the position of an upstream part from the electrical spray nozzles. The harmful substance such as bacteria, viruses and odorous substance contained in the exhaust of the treatment vessel 1 is electrified in reverse polarity for the charged drops of ozone water supplied from the nozzles 4 at the electrical path part 6 and the sucking force between the harmful substance and the sprayed liquid drops is generated to bring the harmful substance into contact with the charged drops of ozone water and the sterilization and the decomposition of the harmful substance are performed. The drain of the exhaust treatment apparatus 3 is passed through a drain discharge pipe 36a and mixed with the treated drainage from the treatment vessel 1.
