摘要：对国际水质污染与控制协会(IAWQ)推出的活性污泥2d号模型（ASM2d)进行优化，使之能够模拟含有菌胶团的污水处理工艺。使用改良后的ASM2d模型模拟并分析了有机物、氮和磷在DE型双沟式氧化沟中的降解过程，发现优化后模型能够较好地拟合这些物质的降解过程。依据所建立的模型计算出各组分在DE型氧化沟中1个周期4个阶段的转化速率，该结果有助于深入分析有机物、氮及磷不同形态之间的转化规律。

Abstract: Activated sludge model 2d (ASM2d) proposed by IA WQ was modified,and it was used to simulate wastewater treatment containing biomass flocs. Combined with the operation parameters of a double channel DE-oxidation ditch, a calculated model was built to simulate carbon, nitrogen and phosphorus degradation processes. The results showed that it could fit the experiment data well. The removal rates of pollutant in the four phases in a cycle were also calculated. And the analyses provided an insight in the nitrification,denitrification and phosphorus removal mechanisms in such operation system,which was useful for the system diagnosis and optimization.

由于污水组分和活性污泥法的复杂性，必须开展数学模型研究，才能对其进行更加深人研究1。
