| 摘 要： | 在常温、低氨氮浓度下,通过控制DOC质量浓度在0.5～1.2 mg/L,在SBR反应器中成功实现短程硝化与同时硝化反硝化工艺的耦合;亚硝酸累积率达到78.5%,总氮损失率达到28.1%;研究了有机负荷和pH对耦合工艺的影响,结果表明,有机物负荷增加有利于提高耦合工艺总氮的去除率,负荷从0.11上升到0.47时,TN的去除率从18.0%上升至41.9%;本实验条件下耦合工艺最佳pH在7.6左右.

| Abstract: | Under the conditions of constant temperature and low concentration of ammonia and nitrogen,the coupling process of short-cut nitrification and simultaneous nitrification and denitrification(SND) is realized in the SBR through controlling the dissolved oxygen(DO) to be 0.5~1.2 g/L.The accumulation rate of nitrite and the losing rate of total nitrogen achieved 78.5% and 28.1 respectively.The effects of organic loading and pH on the coupling process were analyzed,and the results indicate that with the increase... |
