摘　　要：研究以设计规模为80万t的竹园一厂、二厂提标改造(升级补量)工程为建模对象,在污水处理模拟软件WEST中建立了包含深度处理的污水处理厂全流程处理工艺模型,并用蒙特卡洛模拟法对模型参数进行校准。模拟结果表明,模型能较好地模拟污水处理厂的出水水质以及内外回流污泥浓度,总体相对误差<20%。研究所采用的建模过程、模型及参数校准方法能为同类型污水处理厂的建模模拟提供技术参考。This study focuses on the modeling of the upgrading and reconstruction(upgrading and supplementation)project of Shanghai Zhuyuan No.1 and No.2 WWTP with a design capacity of 800000 m^(3)/d.A full-scale treatment process model of the WWTP,including advanced treatment,is established in wastewater treatment modeling software WEST.The Monte Carlo simulation method is used to calibrate the model parameters.The simulation results show that the model can simulate the effluent water quality of the WWTP and the concentration of internal and external return sludge well,with an overall relative error of less than 20%.The modeling procedure,models,and parameter calibration methods used in this study can provide technical reference for the modeling and simulation of similar WWTPs.
