| Abstract: | This paper discusses the three processes of the modified A2/O adopted in phase two of the project in a sewage treatment plant,in view of its process flow and the actual operation situation.The running results show that the improved A2/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. |
