Abstract

Abstract

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%.
