摘要
基于ASM2d模型建立了稳定运行的MUCT工艺营养物质去除过程的动力学反应模型,比较各种COD、TN、NH 4+-N、TP的实测值和模拟值,以确定系统在低C/N条件下运行时的动力学和化学计量学参数.模拟结果表明,稳态模型中的动力学参数qPHA、KA、KPP、YPO3-4、μAUT和ηNO-3分别取值2.90 g.(g.d)-1、3.85 g.m-3、1.35 g.(g.d)-1、0.35、1.6和0.8.其他的动力学和化学计量学参数可采用IWA给出的默认值.
Basing on ASM2d,established a mathematical model to describe the transformation of COD,TN,NH＋4-N and TP.In terms of comparison between simulation and observed values,the kinetics and stoichiometric parameters were established in MUCT process treating a wastewater with low C/N ratio.The results showed that,the qPHA,KA,KPP,YPO3-4,μAUT and ηNO-3 were 2.90 g·（g·d）-1,3.85 g·m-3,1.35 g·（g·d）-1,0.35,1.6 and 0.8,respectively.The typical parameters given by the ASM2d were used as others kinetic and stoichiometric parameters.
