摘　　要： 采用侧沟式膜泥法一体化OCO工艺处理模拟生活污水,考察了DO、HRT和C/N 3种影响因素对模拟生活污水脱氮的效果。研究结果表明:在好氧区DO为2 mg/L左右、HRT=12 h、C/N为7.5左右时,具有较理想的脱氮效果,TN去除率达到了80%;试验还表明本工艺具有较强的抗冲击负荷能力。 Using side channel integral OCO process comprised bio-film and activated sludge to treat simulated domestic sewage, three influencing factors, DO, HRT and the C/N, were studied for nitrogen removal. The results show that the TN removal efficiency is satisfactory and achieves 80% , when DO in the oxic zone is about 2 mg/L,HRT is 12 h,C/N ratios is about 7.5. The test results also show that the integral OCO process has powerful resistance to load shock.
