摘　　要：曝气环节是活性污泥法的重要单元,也是能耗最大的单元,为污染物的好氧生化处理提供所必需的氧气。曝气控制的研究对于出水水质的提高和运营成本的节省具有重要意义。随着污水处理技术的发展,曝气控制也越来越精细化。其中,传统曝气控制系统以反馈微调为核心,新型曝气控制系统包括以模型计算为核心的精确曝气控制和以规则推理为核心的智能曝气控制。针对上述控制系统的运作规律、实现方式进行综述;对现有的曝气控制系统进行评价,从控制参数、控制方式、硬件和软件等方面提出优化建议,并对曝气控制系统的前景进行展望。Aeration tank is an important unit of activated sludge process, and also the unit with the largest energy consumption, which provides necessary oxygen for the treatment of pollutants by aerobic biochemical process. The study of aeration control is of great significance for the improvement of effluent water quality and saving of operation cost. With the development of wastewater treatment technology, the control of aeration is becoming more and more refined. The traditional aeration control takes feedback and fine-tuning as the core, the new aeration control system includes precise aeration control with the core of model calculation, and intelligent aeration control with the core of rule-based reasoning. In this paper, the operation regulation and implementation method of the control system were summarized, then, the existing aeration control system was evaluated, and some optimization suggestions were put forward from the aspects of control parameters, control modes, hardware and software. Finally, the prospect of aeration control system was prospected.
