| 中文摘要 |
| 采用ASBR厌氧氨氧化反应器，研究了ANAMMOX反应器在全海水盐度（100%海水比例）下的抑制及恢复特性.结果表明受到盐度抑制后，ANAMMOX反应器的容积氮去除负荷（NRR）在经过了对盐度响应的敏感期、过渡稳定期和恢复期后可以再次进入稳定期，稳定期的NRR可达0.52 kg·（m3·d）-1，与对照组[10%海水比例，NRR为0.462 kg·（m3·d）-1]接近.对修正的Logistic模型和修正的Gompertz模型做了改进，拓展了模型的适应性.推荐使用再次修正的Logistic模型，对受到全海水盐度抑制后的NRR恢复过程进行模拟.通过建立ANAMMOX反应器NRR恢复时间的预测公式，得到了全海水盐度下NRR的倍增周期为11.359 d. |
| 英文摘要 |
| An anaerobic sequencing batch reactor (ASBR) was operated to investigate the recovery performance of ANAMMOX reactor after the inhibition of 100% seawater concentration. The results showed that the nitrogen removal performance of ANAMMOX reactor suffered inhibition of high salinity concentration. However, it could enter a period of stable nitrogen removal efficiency again after an interim stable period and a recovery period. The nitrogen removal rate (NRR) could reach 0.52 kg·(m3·d)-1, which was similar to the control group, containing 10% seawater and having a NRR of 0.462 kg·(m3·d)-1. The modified Logistic model and modified Gompertz model were revised and their application field was broadened. The re-modified Logistic model was suggested to be used to simulate the NRR recovery process of ANAMMOX reactor that suffered inhibition of 100% seawater concentration. The doubling time of NRR was calculated to be 11.359 d using the prediction formula established for the recovery time of NRR. |
