| 摘 要： | 采用间歇曝气序批式反应器(SBR)工艺,通过曝气时间、交替次数的调整对该系统的脱氮除磷效果进行了研究,最终将工艺确定为厌氧1.5 h、好氧1.0 h、缺氧1.0 h、好氧20 min、缺氧1.0 h、好氧20 min.同时进行批式试验,对不同阶段的反硝化除磷菌(DPAOs)占除磷菌(PAOs)的比例进行了计算.结果表明:该系统与最初的厌氧/好氧SBR相比节省了44%的曝气量,且对COD、总氮、氨氮和磷的去除率分别达88%、89%、100%和100%,系统中DPAOs所占比例为39%.

| Abstract: | Asequencing batch reactor with intermittent aeration had been used for simultaneous biological nitrogen and phosphorus removal in this paper.The removal efficiency for N and P were explored by altering aeration duration and frequency and the optimum operation conditions was listed below,i.e.,1.5 h anaerobic followed by 1.0 h aerobic period,then 1.0 h anoxic followed by 20 min aerobic period,and then 1.0 h anoxic followed by 20 min aerobic.The proportion of denitrifying PAOs(DPAOs)to PAOs was calculated through batch experiments.The calculated results showed that comparing with original A/O SBR reactor,the oxygen supply could be saved ca.44% in this SRR reactor with 39% DPAOs and the removal efficiency for COD,total nitrogen,ammonia and phosphorus was 88%,89%,100% and 100%,respectively. |
