不同进水条件下ASM1模型参数的灵敏度分析
Sensitivity analysis of ASM1parameters under different influent conditions
【摘要】 编制了BSM1的仿真程序,并分析了不同进水条件下ASM1模型的16个参数对BSM1出水COD、TN、NH+4-N、NO3--N灵敏度的影响。结果表明,9个参数的灵敏度在规定的划分范围内没有区别,7个参数在不同进水条件下差别较明显;各参数灵敏度的变化规律,与出水的NH+4-N及NO3--N浓度变化有一定相关性;灵敏度变化与ASM1模型速率方程中的开关函数有关。研究不同进水条件下模型参数的灵敏度,有助于提高污水处理仿真计算的准确性。
【Abstract】 The simulation program of the benchmark process BSM1was completed to investigate the effect of different influent conditions on sensitivities of 16ASM1parameters to the effluent COD,TN,NH+ 4-N and NO3-N.The results show that 9parameters are influenced little while 7parameters are affected observably by the influent conditions;Sensitivity variation rules of parameters have certain correlations with the effluent concentrations of NH+ 4-N and NO3-N,and the changes of sensitivity relate to the switching functions in process rate equations of ASM1.Studying the sensitivities of model parameters under different influents can help increase the accuracy of simulation for wastewater treatment.
