研究了两段序批式活性污泥法（TSSBR）处理高COD、高氮浓度化工废水的启动运行和过程控制。采用溶解氧（DO）、氧化还原电位（ORP）和pH等工艺变量进行控制。常规SBR试验结果表明，根据COD去除和硝化过渡阶段的DO和pH断点，有机物降解和硝化可以分离，并在两个不同的反应器中发生，称为TSSBR。为了提高工艺的灵活性和节省曝气能耗，对TSSBR反应器中DO、ORP和pH的变化进行了表征。TSSBR的控制策略是：在SBR 1中，DO和ORP的折点表示COD去除的结束;在SBR 2中，pH曲线上的DO折点和氨谷表示硝化的结束。
The startup operation and process control of a two-stage sequencing batch reactor (TSSBR) was investigated to improve the efficiencies of organic substrate degradation and nitrification via nitrite from a chemical industrial wastewater with high COD and nitrogen concentrations. A control strategy using process variables as dissolved oxygen (DO), oxidation-reduction potential (ORP) and pH was implemented. The conventional SBR test results showed that based on DO and pH breakpoints at the transition of COD removal and nitrification, organic substrate degradation and nitrification could be separated and occurred in two different reactors termed TSSBR. For the purpose of improving the process flexibility and saving aeration energy, the variations of DO, ORP and pH in TSSBR were characterized. The developed control strategy for TSSBR was that in the SBR1, DO and ORP breakpoints indicated the end of COD removal; in the SBR2, the DO breakpoint and ammonia valley on the pH profile represented the end of nitrifica...
