【摘要】 以西安市某污水处理厂实际污泥水为研究对象，采用序批式OA_N反应器对其进行了处理，结果表明：TCOD,TP,NH⁺₄-N和SS的平均去除率分别为93.3%,52.52%,99.87%和88.82%。OA_N反应器中富集硝化菌活性污泥的氨氧化速率（AUR）和亚硝酸盐氧化速率（NUR）平均值分别为7.84 mg/（gMLSS×h）和12.17 mg/（gMLSS×h）,远高于污水处理厂系统活性污泥AUR 2.64 mg/（gMLSS×h）和NUR 2.95 mg/（gMLSS×h）的硝化速率，可将富集硝化菌的活性污泥添加入污水处理厂系统以强化生物脱氮。更多还原

【Abstract】 The reject water was a nitrobacteria-enriched flow and can be treated in the pilot plant OA_N reactor. The result showed that average removal rate of TCOD, TP, NH⁺₄-N and SS were 92.6%, 52.5%, 99.9%, and 88.8%, respectively. OA_N system average ammonia utilization rate（AUR） and nitrogen utilization rate（NUR） were 7.84 mg/（gMLSS×h） and 12.17 mg/（gMLSS×h）, respectively, higher than wastewater-treatment plant system AUR 2.64 mg/（gMLSS×h） and NUR 2.95 mg/（gMLSS×h）. The nitrification rate was much higher than AUR 2.64 mg gMLSS×h and NUR 2.95 mg gMLSS×h in the sewage treatment system. The nitrifying bacteria-enriched activated sludge could be added to the sewage treatment system to enhance biological nitrogen removal.更多还原
