| 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. |
