摘　　要：根据瓦池污水处理厂进水和出水的水质监测数据,采用基于ASMD模型的BioWin软件对该厂A/A/O工艺进行了建模、参数校正和模型验证。以该厂A/A/O工艺好氧池溶解氧为控制目标,利用参数属地化后的模型进行了供气系统运行策略模拟优化。结果表明,采用“两档曝气+局部优化”的供气方式,A/A/O工艺好氧池溶解氧浓度较为稳定,相比于现状所采用的一档运行模式,好氧池溶解氧达标率从46.4%提升至98.2%,曝气能耗降低13.2%,该厂全年鼓风机电费可节省约12万元。According to the measured data of each pollutant index of influents in the plant,the ASMD-based BioWin software was used to model the A/A/O process of the plant,to calibrate the parameters and to validate the model.Taking the dissolved oxygen in A/A/O process aerobic pool as the control target,the model of the plant was used to optimize the operation strategy of the gas supply system.The results show that the concentration of dissolved oxygen in the aerobic tank of the A/A/O process is relatively stable when the fan runs in the"two-step+partial adjustment"mode.Compared with the conventional one-step mode,the standard rate of dissolved oxygen in the aerobic tank increased from 46.4%to 98.2%,the aeration energy consumption could be reduced by 13.2%.The blower electricity cost could save about 120000 RMB per year in the plant.
