The stability of the two-stage SBR system treating dyeing wastewater was investigated during a 120-cycle continuous operation. The system was fed with influent of low dye concentration and high dye concentration. The results showed that the two-stage SBR system was adaptable to the change of influent quality and operation conditions during the long-term operation. It could efficiently remove the pollutants in the wastewater, the average dyestuff and COD removal rates were 81% to 92.5% and 89.4% to 93.1% respectively for low and high influent loading, and could produce continuous good quality effluent. In the two-stage SBR system, the anaerobic sludge had the characteristics of high activity and strong pollutant degradation ability, and the aerobic sludge existed in the form of aggregate structure, which helped stabilize the effluent quality.
在120个周期的连续运行过程中，对两级序批式反应器（SBR）系统处理印染废水的稳定性进行了研究。该系统分别采用低染料浓度和高染料浓度的进水。结果表明，两级SBR系统在长期运行过程中能够适应进水水质和运行条件的变化。它能够有效去除废水中的污染物，对于低进水负荷和高进水负荷，染料平均去除率分别为81%至92.5%，化学需氧量（COD）去除率分别为89.4%至93.1%，并且能够产生连续的优质出水。在两级SBR系统中，厌氧污泥具有活性高、污染物降解能力强的特点，好氧污泥以聚集体结构形式存在，这有助于稳定出水水质。
