| 中文摘要: |
| 厌氧氨氧化是一种高效的脱氮处理工艺，但其启动和运行过程困难，高效反应器是解决此问题的有效手段。本文利用改进的上流式双层厌氧滤器开展厌氧氨氧化启动反应的试验研究。在反应器填料上分别接种反硝化污泥、厌氧污泥、混合污泥，通过模拟废水提供自养反硝化条件，并逐步提高基质浓度和水力负荷，促使菌群向厌氧氨氧化反应转变。试验发现，反硝化污泥、厌氧污泥、混合污泥均可启动厌氧氨氧化反应，启动时间分别为42、54 d和45 d。以反硝化污泥为接种物的启动效果最好，启动时间较短且废水氮素去除率高，总氮去除率最高达到82.2%。双层填料的反应器有效提高了厌氧氨氧化的稳定性，该反应器中厌氧氨氧化菌对氨氮、亚硝氮的适宜浓度负荷为270、360 mg·L-1，废水中COD浓度不宜超过150 mg· L-1，系统中存在厌氧氨氧化和甲烷化共存的效应。 |

| Anammox is an efficient nitrogen removal process, but it is difficult to start-up and operate, and ananammox reactor is the efficient way to resolve this problem. The start-up of anammox reactor by upflow anaerobic filter was studied. Denitrifying sludge, anaerobic sludge, and mixed sludge was inoculated on the packing materials, respectively and an autotrophic denitrification condition was provided by the simulated wastewater influent. Along with the gradual increase of matrix concentration and hydraulic load, the microflora was converted to the anaerobic ammonium oxidation(anammox)reaction. The results showed that the anammox reaction could be started by all the three sludge, and the time of start-up of denitrifying sludge, anaerobic sludge, mixed sludge was 42, 54 days and 45 days, respectively. The best result was that inoculated with denitrifying sludge with 82.2% of the total nitrogen removal rate, which started-up quickly and nitrogen was removed efficiently. Double packing effectively improved the stability of anammox process in the reactor, in which the suitable influent concentration loading for the anammox bacteria was 270 mg·L-1 and 360 mg·L-1 for ammonia nitrogen and nitrite nitrogen, respectively, and the COD concentration could not be more than 150 mg· L-1. Furthermore, there was a coexist-effect for anaerobic ammonia oxidation and methanation in this reactor system. |
