| 摘 要： | 保持进水总流量不变，以一定流量比同时从缺氧区和厌氧区进水，探讨了不同进水流量比(R=Q厌/Q缺)和进水COD浓度对中心岛式一体化OCO工艺脱氮除碳的影响。研究结果表明，进水COD浓度和进水流量比Rs对COD的去除效果影响不大，出水COD浓度一直稳定在50 mg/L以下，去除率在92%以上；进水COD浓度和进水流量比Rs共同决定着系统TN的去除效果，进水COD浓度为100 mg/L、200 mg/L时，TN去除率随着进水流量比Rs的减小呈增加的趋势；当进水COD浓度为 300 mg/L时，TN去除率随着进水流量比Rs的减小呈先升高后降低的趋势，在进水流量比Rs为3∶1时TN去除率最高，达到87%。 |

| Abstract: | Influence of different influent flowrate ratios(R=Qanaerobic/Qanoxic) and COD concentration on the carbon and nitrogen removal by the integral OCO process with the center-island settling tank was studied when the total influent flowrate from anaerobic zone and anoxic zone remains constant.The COD removal efficiencies do not change obviously at different influent Rs and COD,and the effluent COD is less than 50 mg/L,the COD removal rate is more than 92%.The TN removal efficiencies are decided by Rs and COD.Th... |
