| 摘 要： | 活性污泥模型方法正逐渐成为废水处理工程领域科学研究、工艺设计和过程控制的一种重要手段。以国际水质协会的活性污泥1号模型（ASM1为基础，以MATLAB为工具开发模拟软件，对模型进行了校核与验证。模拟了重庆市唐家桥污水处理厂COD和含N组分的降解过程，研究了有机物负荷、流量、温度和溶解氧浓度变化对出水COD、氨氮、硝态氮和总氮的影响。利用所开发的模拟程序对唐家桥污水处理厂的脱氮改造方案进行了优化，并预测了改造后的处理效果。

| Abstract: | Activated sludge model can be used to improve the study,design and operation of the activated sludge process. Activated Sludge Model No.1 published by the IAWQ was applicated to Tangjiaqiao Waste Water Treatment Plant in Chongqing. A simulating software of the model on the basis of MATLAB was developed.The influences of organic loading, influent flow, temperature and dissolved oxygen on effluent COD, NH + 4 N, NO - 3 N and TN were studied.The upgrading design of biological nitrogen removal in Tangjiaqiao WWTP was optimized with the software.The efficiencies of the upgrading design were predicted. |
