摘要: 采用中心岛式一体化OCO工艺处理模拟生活污水，考察了溶解氧(DO)、碳氮比(C/N)、水力停留时间(HRT)和pH值对其脱氮效率的影响。试验结果表明：在好氧区DO为2.0 mg/L左右，C/N为8.5左右，HRT为12 h左右，pH值为7.4～7.8时，该工艺具有较为理想的脱氮效果，达到85%。试验还表明，该工艺的一体化沉淀池具有沉淀效能高、抗水力冲击能力强的特点。

Abstract: Based on the manual simulated domestic sewage as the treatment media，the influences of dissolved oxygen (DO), carbon to nitrogen ratios (C/N), hydraulic retention time (HRT) and pH value on nitrogen removal were studied by the integral OCO process with the centerisland settling tank. The experimental results show that the TN removal efficiency is satisfactory and achieves 85% when DO in the oxic area is about 2 mg/L, C/N ratios is about 8.5, HRT is 12 h, and pH is between 7.4～7.8. This centerisland settling tank of novel integral OCO process has high separating efficiency for solidliquid and powerful resistance to hydraulic load shock.
