| 摘 要： | 利用自行开发的混合呼吸仪,对来自重庆某城市污水处理厂进水和活性污泥混合液进行了呼吸速率测量,得到包含RDCOD和SBCOD降解过程OUR和内源呼吸过程OUR的全呼吸速率曲线.根据所得OUR曲线所表现出的两阶段性特点,以水解模型解析SBCOD的OUR曲线,结合Mann-Kendall趋势检验法解析内源OUR,提出一种呼吸速率测量法同时表征废水中RBCOD和SBCOD的新方法.与传统的OUR台阶法相比,该方法减少了人为误差,能够提高废水COD组分表征的准确性. |
| 关 键 词： | 废水 COD划分 呼吸速率测量 RBCOD SBCOD |

| Abstract: | Respirometry was made using wastewater and activated sludge from a WWTP of Chongqing through self-developed hybrid respirometer.And complete oxygen uptake rate(OUR) curves containing OUR of biodegradation process of RBCOD and SBCOD and endogenous process were obtained.A new method based on respirometry was proposed to characterize RBCOD and SBCOD in wastewater simultaneously,in which hydrolysis model was selected to analyze OUR curves of SBCOD according to the two-phases nature of exogenous OUR and trend-te... |
