The Operating Characteristics of Orbal Oxidation Ditch Process under Low Dissolved Oxygen

Abstract:

Orbal oxidation ditch is widely used in urban sewage treatment system ,Oxygen consumption level is an important index to measure process operating characteristic, discuss the operation mode of Oxidation ditch under low dissolved oxygen concentration condition is the main link of Sewage plants energy saving operation. Through the adjustment of chongqing TongLiang sewage treatment plant Orbal oxidation ditch aerations equipment operation parameters, the operating power reduced 7.5 kW, the removal rate of TN increased from 19% to more than 50%,and COD, BOD₅, TP, NH₃ - N removal rate was not affected, the Water meet the design requirements.
