| Abstract: | In view of the fact that the mass concentration of ammonia nitrogen in wastewater from toilet in tourism areas is high,the key factors that influence the improvement of the A/O biological denitrification process was selected by orthogonal experiment,the relativity between key factors and the removal rate of ammonia-nitrogen,as well as the optimal condition for the process were discussed.The experiment showed that the hydraulic retention time in oxidation phase and nitration oxidation phase were 6 h,when the reflux ratio was 200%,the removal rate of ammonia-nitrogen in wastewater from toilet was above 90%. |

| Keywords: | wastewater from toilet high ammonia-nitrogen concentration biological denitrification A/O process |
