- 摘要:
- 将基于耗氧速率（OUR）气量计算模型和基于进水氨氮负荷DO预测模型相结合的曝气控制系统应用于武汉某污水厂，通过现场应用考察了曝气控制系统运行的稳定性和节能效果。实际运行结果表明，曝气控制系统可以根据进水氨氮负荷合理设定DO值，并根据OUR和DO值计算好氧池的最佳需氧量，将实际DO值控制在设定值±0.315 mg/L范围内；同时曝气控制系统可以保证出水COD和NH3-N满足《城镇污水处理厂污染物排放标准》一级A要求；曝气控制系统可以将鼓风机处理单位体积水的电耗降低21.9%。
- Abstract:
- An aeration control system combining aeration calculation model based on oxygen uptake rate (OUR) and DO prediction model based on ammonia nitrogen load was applied to a wastewater treatment plant in Wuhan,and operational stability and energy saving performance of the aeration control system were investigated. The aeration control system could reasonably set the DO value according to the influent ammonia nitrogen load, calculate the optimal oxygen demand of the aerobic tank according to the OUR and DO values, and control the actual DO value within the range of (set value ±0.315) mg/L. At the same time, the aeration control system could ensure that COD and NH3-N in the effluent meeting the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant, which reduced power consumption of the blower by 21.9% per unit volume of wastewater.
