| 摘要: |
| 为探究不同厌氧运行方式对亚硝化恢复的影响, 在常温(20±2) ℃下, 采用两组两级连续搅拌反应器(CSTR)1#和2#, 实验分为S1、S2和S3三个阶段.在S1阶段1#采用厌氧/厌氧运行(两级DO均为0~0.1 mg/L), 2#采用厌氧/好氧运行(两级DO分别为0~0.1和0.6~0.8 mg/L); 在S2阶段1#转变为好氧/好氧运行(两级DO分别为0.2~0.4和0.6~0.8 mg/L), 2#保持厌氧/好氧不变(两级DO分别为0~0.1和0.6~0.8 mg/L); 在S3阶段, 研究恢复后亚硝化的稳定性, 此时1#、2#两级DO均为1.0~1.2 mg/L.分别对此过程中亚硝化的恢复时间以及恢复后稳定性进行比较.结果表明, 1#的恢复时间比2#缩短了12 d, 但当溶解氧增加到1.0~1.2 mg/L时, 2#恢复后的亚硝化更稳定.先厌氧/厌氧(两级DO均为0~0.1 mg/L)后好氧/好氧运行(两级DO分别为0.2~0.4和0.6~0.8 mg/L), 有利于亚硝化的快速恢复, 恢复后转变为厌氧/好氧运行(两级DO分别为0~0.1和0.6~0.8 mg/L)有助于亚硝化的长期稳定运行.

| Abstract: |
| To investigate different effects of anaerobic modes on recovery of partial nitrification (PN), two-stage continuous stirred-tank reactors (CSTR)1# and 2# were used at room temperature (20±2) ℃. The experiment had three stages (S1, S2 and S3). During S1, 1# was maintained anaerobic / anaerobic (DO: 0-0. 1, 0-0. 1 mg / L), 2# was maintained anaerobic / oxic (DO: 0-0. 1, 0. 6-0. 8 mg / L). During S2, 1# was maintained oxic / oxic (DO: 0. 2-0. 4, 0. 6-0. 8 mg / L), 2# was continually maintained anaerobic / oxic (DO: 0-0. 1, 0. 6-0. 8 mg / L). To investigate stability of PN after recovery, S3 was carried out. During S3, 1# and 2# was maintained oxic / oxic (DO: 1. 0-1. 2, 1. 0-1. 2 mg / L) The following paremeters (time of recovery of PN and stability of PN) were investigated. It demonstrated that the recovery time of 1# was shorter than that of 2# by 12 d. However, PN in 2# was more stable when DO increased to 1. 0-1. 2 mg / L. Efficient PN could be recovered by the mode of first anaerobic / anaerobic (DO: 0-0. 1, 0-0. 1 mg / L) then oxic / oxic (DO: 0. 2-0. 4, 0. 6-0. 8 mg / L). Afterwards, stable PN could be maintained by anaerobic / oxic (DO: 0-0. 1, 0. 6-0. 8 mg / L).
