Two groups of sequencing batch reactors were used to study the metabolism substrate transformation of phosphorus-accumulating organisms (PAO) and glycogen-accumulating organisms (GAO) fed with mixed acetic and propionic acids. Seven stoichiometry parameters and 24 kinetic parameters were contained in the PAO and GAO kinetic model, and stoichiometry parameters were deduced from the stoichiometry models, while kinetic parameters were determined by experimental results. The kinetic model parameters of stoichiometry and kinetics were determined according the experiments and the literature. Subsequently, the substrate transformations of PAO and GAO were calculated by the Matlab software. The model curves matched the SBR experimental data well, indicating that the kinetic model based on SCFAs metabolism could be used to simulate PAO and GAO in anaerobic-aerobic conditions.
使用两组序批式反应器研究了以乙酸和丙酸混合物为进料时聚磷菌（PAO）和聚糖积累菌（GAO）的代谢底物转化。PAO和GAO动力学模型包含7个化学计量参数和24个动力学参数，化学计量参数由化学计量模型推导得出，而动力学参数则由实验结果确定。根据实验和文献确定了化学计量和动力学的动力学模型参数。随后，通过Matlab软件计算了PAO和GAO的底物转化。模型曲线与SBR实验数据吻合良好，表明基于短链脂肪酸代谢的动力学模型可用于模拟厌氧-好氧条件下的PAO和GAO。
