摘　　要：序批式反应器(SBR)因其具有良好的脱氮除磷效果且占地面积小等特点而得到广泛关注与普遍应用。SBR操作的灵活性给控制策略的实施带来了很大难度。建模与仿真是SBR优化运行的基础。本文在连续式活性污泥系统数学模型ASM2d的基础上,根据SBR的时序交替批过程特点,在MATLAB仿真环境下建立了SBR模型,实现对SBR过程的准确模拟。在此基础上,在不同运行模式下,对SBR进行了优化控制。结果表明,采用厌氧、缺氧、好氧多级交替SBR运行模式,在节能和运行时间上能够产生更好的效果。Sequencing batch reactor （SBR）, because of the characteristics of good effects of nitrogen and phosphorus removal and taking up small area, obtained widespread concern and has be applied universally. The implementation of control strategy is a hard work because of the SBR operating flexibility. Modeling and Simulation of SBR is the foundation for optimal operation. This article estab- lished the SBR model in the MATLAB simulation environment, and simulated SBR process accurately based on activated sludge system mathematical model- ASM2d in accordance with the characteristics of SBR＇ timing and batch process by turns. On this basis, carries on optimal control for SBR in different mode of operation. The results showed that it has better effect in the aspects of energy-saving and operation time-saving when using Alternating Anaerobic-Anoxic-Aerobic Sequencing Batch Reactor.
