摘要
本研究考察了厌氧-立体循环一体化氧化沟工艺(AN-IODVC)中厌氧释磷效果及诸影响因素。研究结果表明,AN-IODVC除磷脱氮系统中好氧污泥的VSS/MLSS值比厌氧污泥小,好氧污泥含磷量与厌氧污泥含磷量的差值和TP去除率、厌氧磷释放率及厌氧ORP呈良好的线性相关关系。厌氧磷释放的最佳条件为:污水COD/TP>55,维持厌氧区ORP低于-400 mV。
Anaerobic phosphate release rate and its affecting parameters were studied in an anaerobic-integrated oxidation ditch with vertical circle regime system （ AN-IODVC）. The resuh showed that the VSS/MLSS in aerobic phase was lower than that in the anaerobic phase, and the difference between phosphorus concentration in aerobic sludge and phosphorus concentration in anaerobic phase was significantly related with TP removal, anaerobic phosphorus release and ORP in the anaerobic phase. The optimal condition for anaerobic phosphorus release were concluded as follows ： COD/TP 〉 55, keeping ORP in anaerobic column below - 400 mV.
