| 摘 要： | 采用循环式活性污泥法(CAST)处理模拟生活污水，通过控制曝气量，使反应器中DO在0.13～0.74 mg/L之间，在常温下快速实现亚硝酸型硝化，然后增大曝气量使反应器内DO在0.7～3.36 mg/L之间，控制曝气时间1.5 h，考察系统内亚硝酸型硝化的维持情况。结果表明，14℃条件下，通过先控制低溶解氧浓度再控制曝... |

| Abstract: | Simulated domestic sewage was treated through the cyclic activated sludge technology(CAST),results showed that through aeration duration control,partial nitrification was carried out in a lab-scale SBR at normal temperature,when DO concentration ranged from 0.13 mg/L to 0.74 mg/L,and partial nitrification was maintained for a long time when DO concentration rised to 0.7~3.36 mg/L.Accumulation rate of nitrite was steadily kept over 90%,average total nitrogen removal rate of effluent was 68% after a sludge re... |
| Keywords: | partial nitrification normal temperature low DO concentration ammonia oxidation rate |
