摘　　要：以复合式A/O工艺缺氧段动力学模型为基础,根据物料平衡理论、反应-扩散理论和Fick定律建立了复合式A/O工艺好氧段的底物降解和微生物增殖动力学模型,并进行了验证。结果表明,模型对好氧段出水的COD浓度和微生物增殖浓度拟合良好,偏差率始终低于20%;在进水底物充足的情况下,模型能够较好地模拟氨氮的硝化反应过程。Based on kinetics model of anoxic stage in hybrid A/O process, the kinetics model for substrate degradation and microorganism growth in aerobic phase of hybrid A/O process was established and verified according to the mass balance theory, reaction-diffusion theory and Fick law. The results show that the model coincides well with the COD concentration and microorganism growth concentration in the outflow from the aerobic stage, and the deviation rate is always under 20%. As the substrates in the inflow are sufficient, nitrification can also be simulated well by the model.
