摘要
为了深入研究厌氧氨氧化（ANAMMOX）新型生物脱氮工艺，减轻水体氮素污染，防止水体富营养化，用无纺布填料进行了ANAMMOX细菌的培养和富集，并通过批武实验研究了DO存在时ANAMMOX反应的可行性及其在HABR反应器中的运行性能．实验结果表明，在有氧条件下能够发生ANAMMOX反应，反应器中同时存在好氧氨氧化菌和厌氧氨氧化菌的协同作用．D0浓度为1．0～6．47mg／L时，ANAMMOX细菌活性较低，NH4^＋-N和NO2^--N降解速率分别为1．52mg／（L·h）和1．83mg／（L·h）；当D0浓度小于1．0mg／L时，ANAMMOX细菌活性升高，降解速率分别达到3．40mg／（L·h）和3．98mg／（L·h）．ANAMMOX工艺可以在HABR反应器中实现，受D0、温度等因素的影响，TN去除负荷较低，只有0．01kg／（m^3·d）．
In order to eliminate nitrogen pollution of water body and to prevent eutrophication, anaerobic ammonium oxidation （ANAMMOX） nitrogen removal process was studied. The ANAMMOX bacterial was cultivated and enriched on the non-woven carrier. The feasibility of ANAMMOX reaction in the presence of the disolved oxygen （DO） in the batch experiment and the performance of ANAMMOX process in a HABR reactor were discussed. The results show that ANAMMOX reaction can occur in the presence of DO and the relationship of cooperation between aerobic ammonium bacterial and ANAMMOX bacterial can be realized. When DO concentration is 1-6. 47 mg/L, the degradation rates of NH4^＋-N and NO2^--N are 1.52 mg/（L ·h） and 1.83 mg/（L · h）, whereas DO concentration decreases below 1 mg/L, the degradation rates increase to 3. 40 mg/（L · h） and 3. 98 mg/（L · h）. The ANAMMOX process can be realized in the HABR reactor, but TN removal loading rate is only 0. 01 kg/（m^3 · d） due to the influence of DO and temperature.
