| 摘 要： | 通过正交试验研究了溶解氧（DO）、污泥浓度（MLSS）、污泥回流比（R）对改良型氧化沟脱氮除磷效果的影响。极差分析结果表明,影响CODCr、TN、TP去除率各因素的重要性顺序分别为：DO〉MLSS〉R、DO〉R〉MLSS、MLSS〉R〉DO。方差分析结果表明,DO和MLSS对脱碳具有较显著的影响,DO对脱氮具有较显著的影响,MLSS、R对除磷具有较显著的影响。改良型氧化沟脱氮除磷的最佳运行工况为氧化沟缺氧区DO=0.3-0.5 mg/L、好氧区DO=2.0-2.5 mg/L,MLSS=5 000 mg/L,污泥回流比R=65%。

| Abstract: | The effects of dissolved oxygen（DO）,mixed liquid suspended solids（MLSS） and sludge return ratio（R） on nitrogen and phosphorus removal of improved oxidation ditch were studied through orthogonal experimental.The results of range analysis show that the importance sequences of the factors influencing the removal of CODCr,TN,TP are DO〉MLSS〉 R,DO〉R〉MLSS,MLSS〉R〉DO,respectively.The results of variance analysis show that,DO and MLSS have significant influence on decarburization,and DO also has significant influence on nitrogen removal,MLSS and R have significant influence on phosphorus removal.In the end,it is obtained that,the best operating conditions of improved oxidation ditch for nitrogen and phosphorus removal is that the concentration of anoxic zone and aerobic zone of improved oxidation ditch was 0.3 to 0.5mg/L and 2.0~2.5mg/L,MLSS is 5000mg/L,sludge return ratio R is 65%. |
