| 摘 要： | 在SBR污水处理系统中应用呼吸速率测定仪对活性污泥的呼吸速率进行测定,探讨了污泥浓度和温度对内源呼吸速率的影响.对大量的比内源呼吸速率数据进行处理后发现,在混合液温度基本不变的基础上,内源呼吸速率与污泥浓度变化趋势一致,即比内源呼吸速率与污泥浓度无关;而温度对比内源呼吸速率的影响十分显著.这些结论为呼吸速率成为SBR工艺的控制参数提供了基础. |
| 关 键 词： | SBR 内源呼吸速率 MLSS 温度 |

| Abstract: | The endogenous respiration rate of activate sludge in SBR was measured.The effects of MLSS and temperatures on endogenous respiration rate were discusssed.It was found that when the temperatures of mixed liquid were basically unchanged,the change trend of the endogenous respiration rate was consistent with that of MLSS,that is ,the specific endogenous respiration rate was not related to MLSS.The effect of temperatures on endogenous respiration rate was significant.These conclusions provide a basis for endogenous respiration rate becoming a control parameter of SBR. |
| Keywords: | SBR endogenous respiration rate MLSS temperature |
