| 摘 要： | 为考察污泥龄与高浓度含氮废水亚硝化稳定性之间的关系,采用连续进水、间歇排水SBR工艺,当水力停留时间为0.75 d,污泥停留时间为3 d时,系统亚硝化率约为75%和氨氮降解率约为60%。试验结果证明SRT控制在一定范围内能实现对硝酸菌的洗出,使亚硝酸菌占据系统中的优势地位,从而保证了系统较高的亚硝化率。

| Abstract: | The relationship of activated sludge retention time and the nitrosation stability of high concentration nitric wastewater is examined.In continous influent and intermittent effluent SBR system,when the HRT is(0.75 d),the SRT is(3 d),the best nitrosation ratio is about 75% and the degradation ratio of NH_3N is about 60%.Through this experiment,the nitrifiers can be removed from the system when SRT is suitable,then the nitrospira will be dominant and the system has high nitrosation ratio. |
