| 摘 要： | 采用泳动床反应器对含高浓度氨氮的污泥脱滤液进行了半硝化反应影响因素研究。实验结果表明,半硝化工艺可以在较高负荷条件下运行,其出水NO2--N/NH4+-N比例稳定在1.1±0.05∶1,基本满足了厌氧氨氧化工艺的进水要求。此外,温度和溶解氧对工艺运行具有重要影响,控制适宜无机碳含量与NH4+-N比值、碱度与氨氮比值有利于半硝化工艺的进行。

| Abstract: | This study was to investigate the influencing factors of partial nitrification(PN) process for the treatment of reject wastewater with high concentration ammonium in a lab-scale swim-bed reactor.The experimental results showed that the effluent ratio of NO-2-N/NH+4-N was maintained 1.1±0.05∶1 when the PN reactor was operated at a high nitrogen loading rate,adjusting to meet influent substrate demand of the anaerobic ammonium oxidation(Anammox) reactor.Moreover,the temperature and dissolved oxygen concentration had a great impact on PN reactor.The suitable ratio of IC/NH+4-N and alkalinity/NH+4-N can be propitious to PN process. |
