| 摘 要： | 考察了PAC-MF系统启动阶段在不同水力停留时间(HRT)下的生物除氮的效果;同时,以硝化速率法表征硝化活性,研究了胞外聚合物(EPS)对硝化菌活性的影响.结果表明,HRT较短的1#系统启动完成所需的时间、NO2-—N积累持续的时间均大于2#系统,NH4+—N的去除效果远远差于2#系统;EPS对硝化活性的抑制作用存在一个临界质量浓度,由硝化速率法得到的临界质量浓度为10 mg/L.

| Abstract: | The effect of biological removal of nitrogen by PAC-MF system at start-up phase under different hydraulic retention time(HRT) was investigated,and nitrification activity was characterized by nitrification rate method,the impact of EPS on the nitrification activity was studied in this paper.The results indicated that system 1 of shorter HRT took longer time to start up,and the accumulation of nitrite lasted longer than system 2,the removal efficiency for ammonia-nitrogen of system 1 was worse than system 2;a critical concentration of EPS was present when discussed the inhibition of EPS on nitrifying activity,the critical concentration get by nitrification rate method was 10 mg/L. |
