| Abstract: | This paper discusses the three processes of the modified A^2/O adopted in phase two of the project in a sewage treat- ment plant, in view of its process flow and the actual operation situation. The running results show that the improved A^2/O treatment effect is stable, and the phosphorus and nitrogen removal effect is good, suitable for large-scale sewage treatment plant. The effluent can meet the national discharge standards through secondary treatment, and the effluent after the third class treatment is capable of the use as reclaimed water. |
