反硝化的

The nitrogen ammonia nitrite and nitrate degradation rate of stable operation autotrophic denitrifying process are about 15～33%、65～90% and 50%.

稳定运行的自养反亚硝化系统的NH〓-N降解率在15～33%、NO〓-N降解率在65～90%、NO〓-N降解率大多处于50%左右。

The activated sludge in nitrous nitrifying process and autotrophic denitrifying process are fully studied, and the characteristics of these processes in stable and acclimation stage have been drawed.

对亚硝化工艺和自养反亚硝化工艺的污泥相变化进行了仔细研究，得出各工艺稳定运行及污泥适应等阶段的特征污泥相。

The streptomyces was found for the first time to be able to oxidize ammonia to nitrite. The denitrifying bacteria were found for the first time to be able to oxidize ammonia anaerobically. The ANAMMOX bacteria were isolated for the first time in pure culture and a new method for ANAMMOX bacteria isolation was developed.

首次发现链霉菌具有亚硝化能力，首次发现反硝化细菌具有ANAMMOX能力，首次获得具有ANAMMOX活性的腐霉状菌纯培养物，并建立ANAMMOX菌的分离方法。

After comparison of various process, a optimum process—ANIS process can be drawn; A autotrophic denitrifying process is successfully started up and stable operated; ANIS nitrous nitrifying process and autotrophic denitrifying process are joining-up in series to operate, and sound nitrogen removal effect can be achieved.

本论文广泛研究了各类C/N均小于1、甚至低至0.5以下的低、中、高氨氮浓度废水进行亚硝化处理的效果，综合比较了各种不同的处理工艺，得出了最佳工艺——ANIS工艺和运行条件；成功启动并稳定运行了自养反亚硝化系统，并将ANIS亚硝化工艺和自养反亚硝化工艺串连运行，取得了良好的脱氮效果。

In addition, under the above-selected nitrosification condition, the immobilized cells N4 and B08 were used for the combined short-cut biodenitriflcation with the ratio of immobilized cells 1:1 and the seed volume 15%, 27h the denitrogenation efficiency reached 97.53%; the immobilized cells N4 and B08 were used to do denitrogenation application test on eutrophic lake water of our school, 12h the NH4+-N removal rate was 84.06%.

在以上所选亚硝化条件下，按1：1的比例，亚硝化细菌N_4和反硝化细菌B_(08)固定化细胞接种量为15％，广西大学硕士学位论文固定化微生物捷径生物脱氮的研究作联合捷径脱氮试验，27h脱氮率为97.53%；并作本校富营养化湖水的脱氮应用试验，处理12h，NH4十一N去除率为84.06%。

The sludge of autotrophic denitrifying process is flocculent、 dispersal、irregularity-shape, existing a number of sphaerotilus.

9自养反亚硝化系统污泥呈絮状、絮体分散、形状不规则，存在一定数量的丝状菌。
