影响侧沟式膜泥法一体化OCO工艺脱氮效率的因素研究
Study on influencing factors of nitrogen removal by side channel integral OCO process with bio-film and activated sludge
【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。
【Abstract】 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.
