| 摘 要： | 在传统OCO工艺基础上设计了一体化OCO工艺，在厌氧区放置填料，将二沉池和生物反应器合建，并就水力停留时间(HRT)对生物反应器脱氮除碳的影响进行研究。在进水COD为260～360 mg/L，好氧区DO为2 mg/L左右，缺氧区<0.5 mg/L，MLSS为4 500 mg/L左右时，分别研究了不同HRT下的脱氮除碳效果。研究结果表明：随着HRT的逐渐增大，出水COD值无明显波动，COD去除率达到90%以上，出水氨氮随着HRT的增大而降低；但仅当HRT为12 h左右时，氨氮和总氮均有良好的去除效果，去除率分别可达到93%和80%。 |

| Abstract: | Based on the classic OCO process,a novel integrated OCO process with bio-flim in the anaerobic zone and side channel integral settlement tank was developed.Influences of hydraulic retention time(HRT) on the nitrogen removal were studied when the influent COD was 260~360 mg/L,DO was more than 2 mg/L in the oxic zone,DO was less than 0.5 mg/L in the anoxic zone,MLSS was about 4 500 mg/L.The results showed that there was no change with the effluent COD obviously,the COD removal rate was more than 90%,the efflu... |
