| 摘 要： | 国际水协(IAWQ)推出的ASM1、ASM2、ASM2D号模型中描述微生物的衰亡过程采用了死亡-再生模式,而ASM3号模型中描述微生物的衰亡则采用了传统减衰模式,文章从两种减衰模式的机理出发,指出了两者之间的区别与联系,并详细推导了两种减衰模式中各参数之间的关系,以此得出了异养菌传统减衰系数bH'和死亡-再生减衰系数bH的测定计算方法。文中在20℃条件下,对以印染废水为主的实际污水处理厂活性污泥的异养菌减衰系数bH'和bH进行了测定,所得结果分别为0.20和0.50。 |

| Abstract: | Death-regeneration decay model was adopted in ASM1, ASM2 and ASM2D while traditional decay model was accepted in ASM3 according to the presentation by IAWQ. The relationship among parameters in these two models was analysed theoretically to provide measurement method of traditional decay coefficient and death- regeneration decay coefficient for heterotrophic bacteria. Finally, proposed method was successfully tested on activated sludge in a full scale dyeing wastewater treatment plant at 20℃, with decay coefficient of heterotrophic bacteria of 0.20 and 0.50 respectively. |
| Keywords: | decay coefficient death regeneration heterotrophic bacteria |
