摘要:
在废水生物处理的过程中,氧化还原电位(ORP)与污染物的浓度以及生化反应进行的程度有着良好的相关关系,其对判断反应器的运行状态,节省能源,提高反应器的运行效果具有重要的指导作用。介绍了ORP作为有机物降解过程及硝化过程的控制参数在好氧生物处理中的控制策略,ORP作为反硝化过程的控制参数在缺氧生物过程中的控制策略,以及ORP作为控制参数在厌氧发酵以及厌氧释磷中的应用。

Abstract:
In the process of biological wastewater treatment,there is a good relationship between ORP and theconcentration of the pollutant. It has important guiding effects on the judgement of running status of reactor,energysaving,and the improvement of reactor running effectiveness. The ORP control strategies used as a control parameterof organic degradation process and nitrification process in aerobic biological treatment,as a control parameter ofdenitrification process in anoxic biological treatment and as a control parameter applied to anoxic fermentation andanaerobic phosphorus releasing are introduced.
