摘　　要：主要阐述了3种不同基质(乙酸盐、丙酸盐、葡萄糖)下聚磷菌(PAOs)和聚糖菌(GAOs)厌氧阶段的代谢模型,对比分析了不同代谢模型下的化学计量系数的差别及其对PAOs和GAOs竞争的影响。针对目前代谢模型主要集中于化学计量学方面,提出今后应在动力学及相关代谢中酶的活动方面进行深入研究。The anaerobic metabolic models of phosphorus accumulating organisms （PAOs） and glycogen accumulating organisms （GAOs） with different substrates（acetate, propionate and glucose） were presented in this paper. The stoichiometry coefficients in different models were found to have impact on the competition between PAOs and GAOs. In addition, as most research so far mainly focused on the stoichiometry of models, the dynamic model and relative activity of enzyme in the biochemical metabolism may be considered for the further research.
