| 摘 要： | 为了探讨实验室筛选获得的氨氧化细菌CM-NR014和反硝化细菌CM-NRD3联合去除市政废水中氮素的应用价值，采用了两级A／O工艺进行菌株去除废水中氮素的小试实验，最后将菌株用于废水脱氮工程中。结果表明，脱氮功能菌实现了短程硝化-反硝化，氨氮去除率在98％以上，总氮去除率在75％以上，COD（化学需氧量）去除率大于90％，出水各项指标均低于城镇污水处理厂污染物排放一级（A）标准。脱氮功能菌在去除市政废水中氮素方面有很高的应用价值，可用于城镇污水处理厂提标改造等。

| Abstract: | Values of ammonia-oxidizing bacteria CM-NRO14 and denitrifying bacteria CM-NRD3 in removing nitrogen from municipal wastewater were investigated. Process of two-stage A/O was conducted. The strains were also added to the wastewater treatment project. The result showed that the strains successfully achieved shortcut nitrification and denitrification in which more than 98% of NH4＋-N, 75% of TN and 90% of COD were removed totally. Effluent reached a standard （A） of urban sewage treatment plant pollutant emissions. Denitrification functional bacteria in the removal of nitrogen in municipal wastewater has a high application value, and can be used to re- form municipal wastewater treatment plant. |
