内源呼吸

CAS污泥的初始污泥活性要远高于MBR污泥，但在内源呼吸和毒性物质的抑制作用下，污泥活性会迅速丧失。

The initial sludge activity of CAS sludge is much higher than that of MBR sludge . However , the sludge activity lose rapidly because of endogenous respiration processes and inhibition of toxic substances .

因为膜的强截留效果，MBR系统对污染物的去除效果和污泥减量效果略优于生物膜系统，其对污泥的减量化主要是通过维持代谢和内源呼吸作用实现的。

Because of strong interception effects of MBR , the removal performance of pollutants and the sludge reduction effect were better than biofilm system . The principle of sludge reduction was endogenous respiration in natural sludge ecosystems .

SBR系统中活性污泥内源呼吸速率的研究

A study on endogenous respiration rate in SBR

而温度对比内源呼吸速率的影响十分显著。

The effect of temperatures on endogenous respiration rate was significant .

而微生物状态决定了内源呼吸的强度和污泥活性等。

The microbiological status determines the intensity of endogenous respiration and activity of the sludge .

细菌种群在内源呼吸期之前的耗氧速率较大，内源呼吸期的耗氧速率较小。

The oxygen consumption rate of bacterial population before endogenous phase is greater than that measured during the endogenous phase .

确定了污泥处于自然的消长平衡状态时的污泥有机负荷，同时测定了污泥增长相关参数：活性污泥微生物合成率和内源呼吸系数。

The organic sludge loading in the state of the balance of activated sludge ′ s growth and decline was determined . Meanwhile , the synthetic ratio and the endogenous respiration coefficient of the activated sludge were obtained .

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；

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 .
