摘　　要：介绍了活性污泥系统仿真软件GPS-X的模型机理及其建模的过程,结合COD组分表征结果,通过实例分析了该软件在污水处理厂中模拟应用,模拟结果为:COD最大误差为5.48%,最小误差为0.83%,相对误差绝对平均值约2.85%;TN最大误差为7.23%,最小误差为0.15%,相对误差绝对平均值约3.62%,NH4+-N最大误差为9.17%,最小误差为1.05%,相对误差绝对平均值约4.98%,模拟结果与实测结果趋势吻合一致,能较好地反映污水处理厂实际状况。The mechanism and the modeling process of the activated sludge system simulation software GPS-X are described, and combined with the results of characterization of COD components, an instance of the software＇s application in a sewage treatment plants is analyzed. The simulation results present the COD with a maximum error of 5. 48%, a minimum error of 0.83%, and an average relative error of 2.85%, TN with a maximum error of 7.23%, a minimum error of 0.15%, and an average relative error of 3.62%, and NH^＋4-N with a maximum error of 9. 17%, a minimum error of 1.05%, and an average relative error of 4.98%. The simulation results match the measured results and reflect the actual situation of sewage treatment plants preferably.
