| 摘 要： | 在SBR反应器中采用消化污泥驯化启动自养半短程硝化系统。在温度35±1℃，溶解氧浓度（DO）1．0～1．5mg／L的条件下，可实现反应器的短程硝化。试验结果表明：反应器进水NH3-N浓度为510mg／L、HRT=12h、DO=0．8～1．2mg／L、pH=7．5～8．3时，SBR反应器出水NO2^--N和NH3-N的平均浓度分别为253．7和246．9mg／L，P（NO2^--N）／p（NH3-N）为1．02，满足ANAMMOX反应器的进水要求。

| Abstract: | Autotrophic half shortcut nitrification process is applied with nitrifying sludge in sequencing batch reactor (SBR).Shortcut nitrification can be got when dissolved oxygen(DO) concentration is 1.0 -1.5 mg/L and temperature is 35±1 ℃.It shows that the influent ammonium concentration is 510 mg/L,HRT is 12 hours,pH is 7.5 to 8.5 and DO concentration is 0.8 to 1.2 mg/L,the effluent NO_2~--N and NH_3-N average concentration are 253.7 and 246.9 mg/L,respectively.When the effluent NO_2~--N/NH_3-N ratio is 1.02,it meets the demand of anaerobic ammonium oxidation. |
