| 摘 要： | 在ASM1模型基础上,结合A/O工艺,建立了A/O工艺污水处理厂模型.通过Matlab软件平台进行数值模拟,探讨了不同污泥龄和内回流比条件下,COD、氨氮和硝酸盐氮出水浓度的变化规律.最后将模拟值与污水排放标准进行比对,得出污泥龄为11 d,内回流比为200%时为最优工况参数.

| Abstract: | The model of A/O WWTP is established based on ASM1 model linked with A/O process.By means of numerical simulation on Matlab,the change laws of concentrations for COD,ammonia nitrogen and nitrate nitrogen are discussed under different sludge retention times and inner recycling ratios.Finally by comparing the values of simulation with sewage discharge standard,the optimal process parameters are obtained: sludge retention time is 11 days and inner recycling ratio is 200%. |
