【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·(m~3·d)~(-1),与对照组[10%海水比例,NRR为0.462 kg·(m~3·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.
[Abstract]:ASBR anaerobic ammonia oxidation reactor was used to study the inhibition and recovery characteristics of ANAMMOX reactor under 100% seawater salinity. The results showed that the volumetric nitrogen removal load (NRR) of the ANAMMOX reactor could enter the stable phase again after the salinity-response sensitive period, the transition stable period and the recovery period after the inhibition of salinity. The NRR of stable stage was 0. 52 kg (mt3 d) ~ (-1), which was close to that of control group [10% seawater, NRR was 0.462 kg (M3 d) -1]. The modified Logistic model and the modified Gompertz model are improved to expand the adaptability of the model. It is recommended that the modified Logistic model be used to simulate the recovery process of NRR after being restrained by the salinity of the whole sea water. By establishing the prediction formula of NRR recovery time in ANAMMOX reactor, the doubling period of NRR under the salinity of seawater was obtained to be 11.359 days.
