| 摘 要： | 微生物的呼吸速率（OUR）在SBR（序批式活性污泥法）的反应工段变化特征明显，与污水中有机物浓度的变化规律相符，在曝气足量时不受曝气不均的影响。为了在确保出水水质的前提下节能降耗，提出了通过软测量技术获得OUR，并将其作为SBR法曝气时间的控制参数，同时在FPGA（现场可编程门阵列）上实现了此控制策略。

| Abstract: | The characteristic change of microorganism's OUR in SBR reaction stage is obvious, which is corresponding with the changing law of organics concentration in sewage, and the OUR is free from uneven aeration when aeration is sufficient. In order to save energy and reduce consumption under the premise of ensuring water quality, the method of getting OUR by soft measurement technology was presented, which was used as SBR aeration time's controlling parameter, and then the control strategy was implemented on FPGA. |
