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。
The simulation program of the benchmark process BSM1 was completed to investigate the effect of different influent conditions on sensitivities of 16 ASM1 parameters to the effluent COD,TN, N H4+-N and NO3--N. The results show that 9 parameters are influenced little while 7 parameters are affected observably by the influent con- ditions;Sensitivity variation rules of parameters have certain correlations with the effluent concentrations of NH4+-N and NO3--N,and the changes of sensitivity relate to the switching functions in process rate equations of ASM1. Stud- ying the sensitivities of model parameters under different influents can help increase the accuracy of simulation for wastewater treatment.
