Advanced sewage water treatment apparatus use of oxidation ditch

摘要

the invention of the oxidation ditch wastewater treatment plant and wastewater treatment plant (oxidation ditch) in the microbial reactions to the use of sewage a technique for processing a height of. ; The purpose of the present invention the sewage removed by treatment with phosphorus and nitrogen in the improvement in the oxidation ditch sewage with the organic matter by the oxidation ditch and to increase the processing capacity to provide an advanced treatment system. ; In order to achieve this objective of installing a mixing tank for mixing and transporting sludge and sewage in oxidation ditch in front of the rear end of its fully capable of aerobic oxidation ditch mixed denitrification tank, anaerobic , separated by the aerobic tank, but the proportion of each size is 8: 6: 2, which was the residence time of the sewage to be a mixture of 2 hours to 16 hours in 6 hours, 8 hours in aerobic, anaerobic denitrification in the aerobic tank ; aerobic denitrification tank evenly installing the air diffuser pipe is configured as a micro-diffuser and the internal and install the inlet manifold is a mixture of sewage and return sludge to be evenly distributed within the aerobic denitrification tank and aerobic denitrification tank In installing the axial flow agitator to circulate the mixed liquor in the ; The dissolved oxygen concentration meter, and an oxidation-reduction potentiometer (ORP) of the blower it was installed so that the oxidation-reduction potential can be maintained at a predetermined value of air volume were able to be linked to install automatic air volume controller with nitrogen gas by denitrification occurs with sufficient oxygen supply in the transition from a mixture of aerobic denitrification hoeryu jonae adjusted, ; The anaerobic prevent the precipitation mixture therein installing the stirrer and prevents the precipitation of the mixed liquor flowing from the aerobic denitrification tank by installing the oxidation-reduction potential meter, and take place due to the residual organic substances and an anaerobic denitrification ; in the aerobic tank to supply sufficient air to give the internal an installation and install the dissolved oxygen analyzer was populated by microorganisms removed by absorption of remaining in the mixture flowing from the anaerobic. ; mixture of sewage leaked from a purification in the following oxidation ditch is a symbol of the final clarifiers The number of settled sludge was discharged and returned mixing tank in front of the oxidation ditch as part of transport sludge and sludge is removed as surplus sludge. ; The present invention can highly improve the existing oxidation ditch treatment to some and can also increase processing capacity is improved the water quality of the discharged water is also excellent treatment effect and the economy.
