摘　　要：采用优化控制SBR工艺对北京某种猪场的养殖粪尿污水进行了中试处理研究。所建立的自控系统通过ORP实时曲线上的"硝酸盐膝点"和pH实时曲线上的"氨谷点"分别对碳源投加和曝气时间进行优化控制,实现根据水质变化适当补充所需碳源,并有效节省曝气能耗。中试反应器10个月的连续运行结果表明,系统对于氨氮和COD的去除率分别达到97%和95%。The pilot-scale sequencing batch reactor（SBR） with optimized real-time control system was developed to study its treatment of swine wastewater.Considering the remarkable variation of influent quality,flexible addition of external carbon source was adjusted according to the ＂nitrate knee＂ on oxidation-reduction potential（ORP） real-time curve,and economic aeration was achieved according to the ＂ammonia valley＂ on pH real-time curve.As a result of this automatic control strategy,the removal ratios of ammonia and COD in ten months＇ operation were kept as 97% and 95%,respectively.
