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。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.
