摘　　要：对上海某大型污水处理厂(原设计处理量为120×104m3/d,采用高效沉淀池处理工艺)进行了工艺优化及模拟改造,介绍了优化模拟改造系统的分析步骤,建立了污水厂达标改造和扩建工艺模型。污水厂达标改造工艺模型模拟结果表明,高效沉淀池的处理出水应根据具体情况,部分进入二级生物处理,以达到排放标准;扩建工艺模拟结果表明,应根据实际进水量和水温情况合理控制DO,出水水质才能达到排放标准。The process optimization and simulation reconstruction of a Shanghai large-scale wastewater treatment plant （WWTP） were carried out. In the original design, the capacity was 120 × 10^4 m^3/d and coagulation-flocculation sedimentation tank （CFST） process was used. The analytical procedures of the process optimization and simulation reconstruction system were introduced, and the models for up-to-standard reconstruction and extension processes of the WWTP were established. The simulation result of the up-to-standard reconstruction process shows that according to the concrete situation, the part of the effluent from CFST should return to the secondary biological tank to reach the discharge standard. The simulation result of the extension process shows that DO should be reasonably controlled according to the WWTP influent load and temperature, so that the effluent quality can achieve the discharge standard.
