【摘要】 以活性污泥 1号模型 (ASM1 )为开发平台 ,建立了简化的活性污泥数学模型 (ASM CN)。该模型主要描述了碳氧化和硝化过程 ,其中模型组分、反应过程和参数的数量都少于ASM1 ,从而提高了该模型在城市污水厂中的实用性。通过测定模型组分、化学计量系数和动力学参数 ,为模型的应用提供了重要的前提和基础。最后利用ASM CN模型对实际城市污水厂的运行进行了动态模拟 ,模拟结果良好 ,验证了ASM CN模型的实用性和有效性 ,并且也验证了模拟程序的准确性。更多还原

【Abstract】 Simplified activated sludge model (ASM CN) is proposed based on the activated sludge model No.1 (ASM1).This model describes the carbon oxidation process and nitration process.The amount of components, processes and parameters of ASM CN is fewer than that of ASM1,so the practicability of ASM CN model is enhanced.The measurement of components and parameters is also studied.Finally,ASM CN model is applied to simulate the operation of actual wastewater treatent plants and good results are achieved.更多还原
