Title: Method for controlling supply of excess sludge to sewage treatment facility and biological reaction vessel
Inventor: SATO AKIO
IPC: C02F3/30
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To accelerate a denitrification reaction and phosphorus release reaction by sending a liquid mixture treated in a biological reaction vessel to a final settling basin where sludge is allowed to settle and aerating part of this sludge with ozone to oxidize the sludge, then controlling the return flow rate thereof according to the oxidation reduction potential of an anaeration tank at the time of returning the sludge to the biological reaction vessel. SOLUTION: The sewage is first admitted into an initial settling basin 10 and the supernatant sewage thereof is sent to the apparatus of the biological reaction vessel 30 consisting of the anaeration tank 31 and aeration tank. The liquid mixture subjected to the biological treatment is sent to the final settling basin 50 where the sludge is allowed to settle. Part of the sludge is withdrawn by a pump 60 and part thereof is admitted into an excess sludge stagnation tank 71 where the excess sludge is oxidized by the ozone diffused from a gas diffuser 81. The excess sludge is then returned through an excess sludge feeding line 72 to the anaeration tank 31.  At this time, the oxidation reduction potential of the liquid mixture in the anaeration tank 31 is measured by a potential measuring instrument 33 and the opening degree of the control valve 23 in the excess sludge feeding line 72 is controlled by a sludge injection adjusting device 22 in such a manner that the measured oxidation reduction potential coincides with a reference potential.
