摘要：研究了有机物对ANAMMOX反应器运行性能的影响.在没有有机物的条件下,进水基质(氨氮和亚硝氮)浓度为70～280mg·L^-1,容积总氮负荷为0.29～0.72kg·m^-3·d^-1,氨氮去除率86.0%～99.7%,亚硝氮去除率88.7%～99.3%.添加有机物(酵母膏100mg·L^-1)后,ANAMMOX反应器运行性能与容积总氮负荷有关.容积总氮负荷低于0.43kg·m^-3·d^-1时,有机物对ANAMMOX反应器运行性能的影响较小,氨氮和亚硝氮去除率保持在94%以上;但当容积总氮负荷为0.72kg·m^-3·d^-1时,有机物对ANAMMOX反应器运行性能产生严重影响,氨氮和亚硝氮去除率降至75%以下.停止添加有机物并降低容积总氮负荷,可在短期内消除有机物对ANAMMOX反应器运行性能的影响.

Abstract：The effect of organic matter on the performance of anaerobic ammonium oxidation (ANAMMOX) reactor was investigated. When the influent did not contain organic matter and the substrate (ammonium and nitrite) concentration was 70～280mg·L^-1, the volumetric total nitrogen loading rate reached 0.29～0.72 kg·m^-3·d^-1, the ammonium removal was 86.0%～99.7% and the nitrite removal was 88.7%～99.3%. The effect of organic matter (yeast extract 100mg·L^-1) was related to the volumetric total nitrogen loading rate. When the volumetric total nitrogen loading rate was lower than 0.43 kg·m^-3·d^-1, no obvious influence was found with the ammonium and nitrite removal higher than 94%. When it was 0.72 kg·m^-3·d^-1, however, serious disturbance was observed with the ammonium and nitrite removal lower than 75%. The disturbance of organic matter to the performance could be recovered within a short period as long as the organic matter was removed and the volumetric total nitrogen loading rate was decreased.
