Abstract

Abstract

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.
- wastewater treatment,
- energy saving,
- aeration control system,
- optimization suggestions
