以人工配制高氨氮低碳氮比（C/N）废水为进水，采用膜生物工艺，通过控制亚硝化池内温度为28～30℃，溶解氧浓度为0．5 mg/L，水力停留时间为12 h，pH 为7．8～8．0，进水氨氮浓度为200 mg/L、CODCr为40 mg/L，在亚硝化池中成功实现了 C/N 为1∶5条件下废水的亚硝化。经过14 d 的运行时间，污泥龄控制在100 d，在膜生物反应器（MBR 反应器）中得到了稳定的亚硝酸盐氮积累。将氨氮浓度分别提高至400和800 mg/L 的情况下，其亚硝化菌的耐受浓度负荷冲击能力均较强。

Taking synthetic wastewater of the high ammonia nitrogen and low C/N ratio as the influent, the membrane bio-reactor (MBR) was used to study establishment of stable nitritation process.The main parameters of the reactor were controlled as follows: the temperature of nitritation tanks was 28-30 ℃, dissolved oxygen (DO) was 0.5 mg/L, HRT was 12 h, pH was 7.8-8.0, influent ammonia concentration was 200 mg/L, CODCr was 40 mg/L.Under these conditions, the nitritation of wastewater with C/N of 1∶5 was realized in the nitritation tanks. After 14 days, sludge age was 100 days, a stable nitrite nitrogen accumulation was achieved.When the ammonia concentration was increased to 400 and 800 mg/L, respectively, the tolerance of nitrosobacteria against shock of high ammonia load was relatively high.
