摘　　要： 在已稳定运行7个月的自养脱硫反硝化反应器中成功富集厌氧氨氧化菌后,利用反硝化菌的不完全反硝化作用为厌氧氨氧化菌提供NO2--N。以NH4+-N、NO3--N和有机物为基质,研究厌氧氨氧化与反硝化的协同作用,并探讨了其最适协同作用条件。反应器的有效容积为2L,遮光放置,通过恒温水浴维持反应器内温度为(33±0.5)℃,并投加活性炭作为填料。结果表明,厌氧氨氧化菌能与反硝化菌共存,反应器可实现厌氧氨氧化与反硝化的协同作用,且最适协同作用条件是:COD/TN=1.46、pH=7.55。 After the ANAMMOX bacteria were successfully enriched in the autotrophic denitrification reactor operated for seven months, the incomplete denitrification of denitrifying bacteria was used to provide NO2- - N for the ANAMMOX bacteria. The synergism between ANAMMOX and denitrification and its optimum conditions were evaluated by using NH4＋ - N, NO3- - N and organic matter as substrates. The effective volume of the reactor is 2 L, the reactor is placed away from direct sunlight, the temperature in the reactor is maintained at （ 33±0.5 ）℃ using a constant temperature controller, and the activated carbon is used as media. The result indicates that the coexistence and the synergism of ANAMMOX bacteria and denitrifiers are achieved. The optimum conditions achieving synergism are COD/ TN = 1.46 and pH = 7.55.
