【摘要】：分析了PU海绵填料-SBBR反应器在无有机碳源条件下处理模拟氨氮废水的启动特性。结果表明,当PU海绵填充率为50%、进水p H值为7.5~7.6时,运行13 d后,氨氮去除率达到70%以上,实现了PU海绵填料-SBBR反应器的快速启动。在启动第16天时,亚硝态氮积累率及总氮去除率分别为72.2%及47.4%,即出现明显的短程硝化反硝化现象。测定典型周期内p H值、DO、ORP参数发现,这三个参数随氨氮的变化表现出明显的不同,对后期反应条件的控制具有指导意义。SEM结果表明,生物膜上的微生物主要由球菌、杆菌及丝状菌构成。PU海绵填料-SBBR反应器通过控制可实现在无外碳源下较高的总氮去除率。
[Abstract]:The start-up characteristics of PU sponge filler-SBBR reactor for treating simulated ammonia nitrogen wastewater without organic carbon source were analyzed. The results showed that when the filling ratio of PU sponge was 50 and the pH value of influent was 7.5 ~ 7.6, the ammonia nitrogen removal rate reached more than 70% after 13 days of operation. The rapid start-up of PU sponge filler and SBBR reactor was realized. On the 16th day, the nitrite accumulation rate and the total nitrogen removal rate were 72.2% and 47.4%, respectively, which showed obvious short-cut nitrification and denitrification phenomenon. It was found that the three parameters were different with the change of ammonia nitrogen in typical cycle. The results of SEM showed that the microbes on biofilm were mainly cocci. The control of bacilli and filamentous bacilli made up of. Pu sponge filler-SBBR reactor can achieve higher removal rate of total nitrogen without external carbon source.
