| Abstract: | Aimed at the difficulty in biological nitrogen removal from low C/N wastewater,the lab-scale step-feed biological nitrogen removal A/O process was used to treat campus sewage,by setting influent points on different sections of the anoxic tank.Denitrification efficiency of step-feed biological nitrogen removal A/O process was investigated under the conditions of sludge reflux ratio of 100%,nitrification liquid reflux ratio of 200% and hydraulic retention time of anoxic tank 2 h,2.4 h,3 h,compared with the co... |
