• 摘要：基于ASm²D模型建立了上海某新建污水厂倒置AAO流程的数学模型,并采用该厂进、出水设计数据对模型进行校正,其中,ASm²D各组分浓度分布参考文献值.同时,通过仿真计算研究了不同温度下进水流量、污泥回流比、混合液回流比及进水流量分配比对出水总化学需氧量(TCOD)、氨氮(S_NH3)、总氮(TN)、总磷(TP)及总悬浮颗粒物(TSS)的影响.结果表明,研究获得的定性和定量两方面结果可供该厂在工艺参数调试中作参考.计算机仿真技术在新建污水厂工艺参数调试中的应用可以减少调试时间,降低调试费用,取得良好的经济效益与环境效益.

• Abstract：An inverse AAO process in a newly built wastewater treatment plant was modeled based on ASm²D. The model was calibrated by using the influent and effluent data in the design specifications of the plant,and the component concentrations of ASm²D were chosen from the literature. The simulation focused on the influence of flow rate,external recycle rate,internal recycle rate,ratio of flows into different reaction tanks,total COD (TCOD),ammonia nitrogen (S_NH3),total nitrogen (TN),total phosphorus (TP),and total suspended particles (TSS). The qualitative and quantitative results may be used as a reference for process parameter adjustment in the newly built plant. A demand for thousands of municipal wastewater treatment plants of different sizes has appeared in China,and strengthening the application of modeling and simulation is very helpful for reducing time and cost in process parameter adjustment.

• Key words：newly built wastewater treatment plant  computational simulation  model calibration  process parameter adjustment
