【摘要】 目前,以国际水协ASM系列(1～3号)为代表的活性污泥数学模型已经广泛地应用于污水处理厂的设计、改建和运行管理以及新工艺和新技术的开发研究。通过对废水组成的详细分析和模型参数的修正,运用ASM2模拟了SUFR(螺旋升流式反应器)系统中COD和氮、磷的去除。模拟结果表明:由模型所得出的模拟值与实测值拟合较好。说明ASM2能够反映COD和氮、磷在SUFR系统中的变化状况。当SUFR系统运行参数发生变化时,模型可以作为有效的预测平台。更多还原

【Abstract】 Currently,the activated sludge models in which the ASM of IWA(International Water Association) have been widely used in the design rebuild and operation of the waste water treatment plant and the development of new technic. By analyzed the composition of water and modified the paramters of ASM2, we use ASM2 to simulate the removing of COD nitrogen and phospherus in the sprial up-flow reacto(SUFR) system. The result indicates that the simulation value tally the fact on the whole. It shows that the ASM2 can primely reflect the change of COD nitrogen and phospherus in SUFR system. When the operational paramters have been changed, the model will be an effective forecast platform.更多还原
