摘要
短程精准曝气智能控制工艺模型摒弃了依靠DO单一数据控制风量的传统控制模式,锚定生化池出水氨氮,包含全自动数据采集与智能控制的工艺模型算法及成套设备。其在汕头1.2万t/d污水处理厂的应用实践结果表明,其可使出水指标稳定达标,可将氨氮目标值控制在0.7~2.8 mg/L范围内;同等条件下,自动运行后单位总还原物需氧的耗能更优,氧利用效率提高约11%;在进水还原物质浓度偏低的情况下,可自动匹配低风量区间,可平均节省18.85%的风量。
The short-range precise aeration and intelligent control process model abandons the traditional control mode that relies on single DO data to control air volume.Anchoring ammonia nitrogen at the outlet of the biochemical tank,it developed a process model algorithm and a complete set of equipment for automatic data acquisition and intelligent control.In the application practice of a sewage treatment plant with a capacity of 12,000 tons per day in Shantou,the effluent index stably complied with the standard,and the target value of ammonia nitrogen concentration was controlled within 0.7 to 2.8 mg/L.Under the same condition,the aerobic energy consumption per unit of total reductive matters after the automatic operation was better,and the oxygen utilization efficiency was increased by about 11%.In the case of low intake reduction material,the low air volume interval can be automatically matched,and the average air volume can be saved by 18.85%.
