| 摘 要： | 实验采用短程硝化工艺处理高氨氮废水,并用PCR-DGGE分析了系统中的微生物区系。结果表明,进水氨氮浓度在50～400mg/L之间梯度增加时,出水氨氮浓度在10mg/L以下;随着氨氮浓度的增加,亚硝态氮积累率逐渐升高,当氨氮浓度达到300mg/L时,积累率达到90%左右。DGGE分析结果表明,随着运行时间的延长,微生物区系多样性减少;氨氮负荷为50mg/L与400mg/L相比,相似性为0.24。

| Abstract: | Shortcut nitrification was used to treat high ammonia nitrogen wastewater,with analysis of microbial communities by PCR-DGGE.Results showed that the system could endure the impact of influent ammonia nitrogen concentration from 50～ 400mg/L,the effluent ammonia nitrogen concentration was below 10mg/L.Along with the increase of influent ammonia nitrogen concentration,accumulation ratio of NO-2-N increased,when the concentration was up to 300mg/L,the accumulation ratio was nearly 90%.DGGE result showed that diversity of microbial community decreased evidently as the time went on.When influent ammonia nitrogen concentration was 50mg/L and 400mg/L,the comparability of microbial community was only 0.24. |
