摘要:采用厌氧附着膜膨胀床（AAFEB）反应器，考察了厌氧氨氧化-羟基磷灰石（Anammox-HAP）耦合工艺在中低温条件下的同步脱氮除磷性能以及颗粒污泥特性和反应器内微生物相对丰度的变化。结果表明，当温度由30 ℃降至25 ℃时，总氮去除率保持在70%~80%之间，总氮去除负荷保持在（2.95±0.09）~（2.69±0.14） kg/（m3·d）；相应地，磷的去除率由61.2%逐渐下降至47.4%，说明25 ℃不利于该系统除磷；该阶段反应器内微生物分泌的EPS总量差别不大，污泥主要呈颗粒状，中部颗粒污泥平均粒径最大，约为650 μm。当温度降至15 ℃时，脱氮除磷效果恶化，总氮去除率由65%逐渐降至23%，总氮去除负荷由（1.14±0.02） kg/（m3·d）逐渐降至（0.23±0.06） kg/（m3·d）；相应地，磷的去除率由48.4%逐渐下降至15.9%；该阶段反应器内EPS产量降低，颗粒污泥出现解体，污泥粒径减小。16S rRNA基因测序发现，厌氧氨氧化菌为主要的脱氮细菌，其中，unclassified_Candidatus_Brocadiaceae的相对丰度始终最高。与上部污泥相比，底部污泥中Candidatus_Kuenenia的相对丰度随温度的降低而上升，反应器底部更利于该菌的生长和繁殖。
Abstract:The performance of simultaneous nitrogen and phosphorus removal, the characteristics of granular sludge and the changes in the relative abundance of microorganisms in the anaerobic ammonium oxidation-hydroxyapatite (Anammox-HAP) coupling process at medium and low temperatures were investigated using an anaerobic attached film expanded bed (AAFEB) reactor. When the temperature decreased from 30 ℃ to 25 ℃, the total nitrogen(TN) removal efficiency was maintained within the range of 70% to 80%, the TN removal rate remained at (2.95±0.09)-(2.69±0.14) kg/(m3·d) ; while the phosphorus removal efficiency gradually decreased from 61.2% to 47.4%, indicating that 25 ℃ was not conducive to the phosphorus removal; in this stage, the total amount of EPS secreted by microorganisms was not much different, the sludge was mainly granular, and the average particle size of the granular sludge in the middle was the largest, about 650 μm. When the temperature dropped to 15 ℃, the effect of nitrogen and phosphorus removal deteriorated, the TN removal efficiency gradually decreased from 65% to 23%, the total nitrogen removal rate gradually decreased from (1.14±0.02) kg/(m3·d) to (0.23±0.06) kg/(m3·d); correspondingly, the removal rate of phosphorus gradually decreased from 48.4% to 15.9%; in this stage, the EPS production decreased, the granular sludge disintegrated, and the sludge particle size decreased. 16S rRNA gene sequencing showed that anaerobic ammonia oxidizing bacteria (AnAOB) was the main denitrifying bacteria in the system, and the relative abundance of unclassified_ Candidateus_Brocadaceae was always the highest. Compared with the upper sludge, the relative abundance of Candidatus_Kuenenia in the bottom sludge increased with decreasing temperature, and the bottom of the reactor was more conducive to the growth and reproduction of this bacteria.
