摘要:

采取厌氧/好氧/好氧/厌氧(AOOA)中试系统处置老龄垃圾渗滤液，经由过程节制DO在0.1~0.5 mg/L等前提成功实现了短程硝化反硝化。在低消融氧和碱度足够的前提下， O1池的NO-2-N堆集率不变在90%以上，系统对NH+4-N和TN的去除率别离高在95%和66.5%，有用处理了老龄垃圾渗滤液的脱氮困难。在节制消融氧为0.3~0.5 mg/L的前提下，O1池进行亚硝化的限制前提是现实水力逗留时候（AHRT），宜节制在13.9 h以上。在一般运转阶段，A1池中的劣势菌种为反硝化菌，而O1池的劣势菌为AOB。另外，O1/O2池实现了NO-2-N的堆集，并在必然水平上构成了同步亚硝化反硝化（SND）系统。

Abstract:

A pilot-scale anaerobic/oxic/oxic/anaerobic (AOOA) process was applied for treatment of mature landfill leachate, and partial nitrification and denitrification was achieved by controlling the dissolved oxygen (DO) to a low value of 0.1-0.5 mg/L. Under the condition of low dissolved oxygen and sufficient alkalinity, the nitrite accumulation rate in the first aerobic reactor(O1)was stably above 90%, and the removal rate of ammonium and total nitrogen of the whole process was higher than 95% and 66.5% respectively, which indicated that AOOA process could effectively solve the difficult problem of nitrogen removal in landfill leachate. The limiting factor of partial nitrification of O1 was the actual hydraulic retention time (AHRT) and should be controlled above 13.9 h under the condition of DO of 0.3-0.5 mg/L. In the normal operation stage, the dominant bacteria in the first anaerobic reactor (A1) were denitrifying bacteria, while the dominant bacteria in the O1 were ammoniaoxidizing bacteria (AOB). In addition, nitrite accumulation was realized in O1/O2, and simultaneous partial nitrification and denitrification (SND) was formed to a certain extent.
