摘　　要：为确保出水水质的稳定达标并实现节能降耗的目的,在白龙港水质净化厂生物池的调试运行中,采用了基于活性污泥模型的生物工艺过程优化控制系统(BIOS),通过数学模型计算并以前馈控制方式对各廊道的溶解氧及内回流比控制值进行优化。结果表明,采用BIOS系统后出水水质稳定且节能效果显著。针对PID方式对于生物池溶解氧进行实时控制的不足,提出采用生物池曝气控制系统(BACS)、以前馈方式根据耗氧速率(OUR)来实时控制曝气量,使溶解氧控制符合生物工艺过程优化控制的要求。通过总结现有曝气管路布置情况下存在的问题,对扩建工程中的供气系统进行了设计改进和优化,确保在二期建设项目中B IOS系统能达到控制目标。In order to ensure the effluent to meet the discharge standard and achieve energy saving and consumption reduction, the bioprocess intelligent optimization system （BIOS） based on the activated sludge model was used during the commissioning of biological reaction tanks in Bailonggang WWTP. The dissolved oxygen set-points and internal reflux rate in all galleries were optimized by the feed-forward control and the model simulation. The results show that after using BIOS, the effluent quality is stable and the energy saving effect is obvious. The bioprocess aeration control system （BACS） can compensate for the deficiency in real-time control of dissolved oxygen in the biological reaction tanks when using PID. BACS controls aeration in real time according to the oxygen uptake rate （OUR） by feed-forward control in order to meet the requirements of bioprocess optimization. Based on the layout of existing aeration pipes, the air supply system in the extension project was improved and optimized to ensure BIOS to reach the control objective in the construction of the second-phase project.
