摘　　要：目前比较成熟的包括脱氮除磷过程的活性污泥模型为ASM2D,但该模型由于参数和过程较多,限制其应用于实际污水处理工艺中。以ASM2D模型为基础,对采用改良型A2/O工艺的武汉市龙王嘴污水处理厂进行稳态和动态模拟。通过调整进水组分百分比与参数,在应用Matlab/Simulink软件后,所得仿真结果与实测值均较吻合,成功验证了模型的有效性与实用性,并可在此基础上实现对污水处理厂的进一步控制研究。The activated sludge model ASM2D,which includes nitrogen and phosphorus remov- al process,is a relatively mature technolgy, but the model parameters：and process are too complicat- ed for the actual application in the sewage treatment process. Based on the ASM2D modeling, the steady--state and dynamic simulation of the improved A2/O process in Wuhan Longwangzui Wastewater Treatment Plant was carried out. Through adjusting the component percentage and pa- rameters of the influent, the modeling results from Matlab/Simulink could meet the measured data, which verified the effectiveness arid practicability of the model. Based on the simulation, further control of the wastewater treatment plant might be made.
