摘要： PURPOSE:To keep the activity of bacteria even when the movement of activated carbon particles is generated by backwashing, in a water treatment apparatus equipped with a biological activated carbon bed, by arranging a dissolved oxygen supply device having a dissolved oxygen injection port provided thereto in the biological activated carbon bed. CONSTITUTION:Bacteria grown using an ozone oxidation product as a nutrition source consume dissolved oxygen in the upper bed part of an activated carbon bed 2 to propagate and, when nutrients are rich and propagation is actively performed, oxygen becomes deficient in the lower bed part of the activated carbon bed 4. Oxygen is sent out of an oxygen cylinder 4 but, at this time, the pressure of oxygen is adjusted by a pressure adjusting valve 5 so that oxygen is not blown in as oxygen gas bubbles and oxygen is introduced into the intermediate bed part of the activated carbon bed 2 from oxygen injection ports 3. Bacteria are propagated using activated carbon particles as a carrier but, when the gaps between particles are filled with bacteria, the pressure loss of water passage becomes large and, therefore, the supply of water from an inflow pipe 9 is stopped in a specific ratio and an air washing valve 12A and a backwashing valve 13A are opened to send air and backwashing water to backwash the biological activated carbon bed 2.

摘要： PURPOSE:To decolor sewage disposal water and to exhance sterilization effect by preventing ultraviolet rays(UV) from being absorbed in colored substance when the UV irradiates by applying ozone treatment to sewage disposal water at a stage before UV irradiation is applied in equipment in the case the sterilization of the sewage disposal water before discharge is performed by the irradiation of the UV. CONSTITUTION:After sludge 3 is sedimented in a sedimentation basin 2, the supernatant liquid of activated sludge 1 is sent to a UV sterilization tank 4, and it is sterilized by applying the UV irradiation by a UV lamp 5. Displosal water is discharged to a river, etc., as discharge water 6. In such a case, an ozone reaction tank 7 is installed at the front stage of the UV sterilization tank 4. The ozone reaction tank 7 performs the ozone treatment of the disposal water by discharging ozonized air generated by an ozone generator 7A to the disposal water by a duffuser pipe 7B and an unreacting ozone is discharged to the air after being decomposed by an exhaust ozone decomposing tower 7C. The following UV sterilization can be effectively performed by performing the decoloring by the ozone treatment in such way.
