摘要
随着污水生物处理技术的进步，很多相关的数学模型被开发出来用以描述污水生物处理工艺的机理，并指导其设计和运行管理。最为著名和应用广泛的当属国际水质协会（IAWQ）推出的活性污泥数学模型系列（Activated Sludge Model 1-3），即ASM模型。通过以反应器动力学为基础，使用活性污泥一号模型（ASM1）对缺氧一好氧生物废水处理工艺建立数学模型并且加以模拟的结果，得出了在不同的工况参数和反应条件（分别是污泥龄，缺氧池与好氧池的体积比，回流和内回流）下各级反应器中污染物质（主要是可溶性有机污染物，氨氮和硝态氮）浓度的变化规律，可以为实际工艺的设计与运行提供参考和依据。
With the development of the biological wastewater treamnt technology, some mathematical models have been recommended to describe the mechanization of biological wastewater treamnet process and guide the design of it. If the process has been completed, they can be used as the reference to the operation and management of it. The most famous and widely used math- ematical model is the ASM（Aetivated Sludge Model） serials, developed by IAWQ. In this paper, I try to simulate the anoxic - oxic treatment process with ASM1, study the influence on the water quality with different parameters involved in the A/O treatment process.
