摘要
建立了活性污泥3号模型应用于氧化沟工艺的活性污泥处理系统数值模型,并利用Matlab语言编制了模拟程序,对模型中的参数进行了灵敏度分析。结果表明,自养菌的产率系数UA最为敏感,对这个参数调整之后,用该模型对一实际工程的出水情况进行模拟,模拟值和实测值取得了较好的吻合。该模型能够反映污水处理的实际运行状况,为模拟污水处理、预测出水水质、优化污水处理厂运行方案提供了可行途径。
A numerical simulation model of Activated Sludge Model No. 3 （ASM3） applied to oxidation ditch process is developed in this paper, and is programmed in Mat lab language. Moreover, sensitivity of parame- ters in the model is analyzed, which indicates that maximal growth rate of nitrobacteria is the most sensitive. Applying the present model to a practical project, the results from modeling had a satisfying agreement with those from the actual ones. It is verified that the present model can represent the actual operation of wastewater treatment, which can be used to offer a way to simulate wastewater treatment, predict water quality and optimize the operating method.
