| 摘 要： | 对基于短程硝化-厌氧氨氧化反应体系实现低氨氮城市生活污水的稳定脱氮进行了实验分析. 稳定时,反应体系的总氮去除率达80%. 对反应器活性污泥中脱氮微生物进行了多样性分析. 结果表明,低溶氧的短程硝化反应器中,与Nitrosomonas europaea/Nitrosococcus mobilis相似性较高的氨氧化细菌,以及分别与Nitrobacter vulgaris 和Nitrospira defluvii相似性较高的亚硝酸盐氧化菌是优势菌种;厌氧氨氧化反应器中,与Kuenenia stuttgartiensis相似性较高的厌氧氨氧化细菌是优势菌种. 并对厌氧氨氧化反应器中总细菌的群落结构进行了解析,发现大量属于Proteobacteria门、Chloroflexi门和Bacteroidetes/Chlorobi门的细菌与anammox细菌共存.

| Abstract: | A partial nitrification-ANAMMOX reactor system for domestic wastewater was set up, and the composition of N-related functional bacteria in the activated sludge were studied. During the stable period, the TN removal rate reached to about 80%. In the partial nitrification system, the dominant AOB is Nitrosomonas europaea/Nitrosococcus mobilis cluster-like bacteria, and the dominant NOB are Nitrobacter vulgaris-like bacteria and Nitrospira defluvii-like bacteria. In the anammox reactor, Kuenenia stuttgartiensis-like bacteria is the dominant anammox bacteria. Numerous members of proteobacteria, Chloroflexi, and Bacteroidetes/Chlorobi phylum are found to co-exist with anammox bacteria. |
