| 摘 要： | 结合广州市猎德污水处理厂A+A2/O工艺的实际运行情况,对其脱氮除磷参数调控和运行效果进行了分析。首先考察了冬天低温条件下的脱氮除磷效果,然后经过不同混合液体积回流比和污泥体积回流比的运行分析,得到适合工艺运行的最佳值,分别为100%和100%,还对其它参数调控进行了简要介绍,最后对工艺整体运行效果进行了分析,得到良好的结果。证明A+A2/O工艺具有良好的脱氮除磷效果。 |
| 关 键 词： | A+A2/O工艺 脱氮除磷 低温 混合液回流比 污泥回流比 污泥负荷 溶解氧 污泥龄 |

| Abstract: | Based on practical running conditions of Liede WWTP in Guangzhou,parameters of A+A2/O process for nitrogen and phosphorus removal and running efficiency were investigated.First,nitrogen and phosphorus removal efficiency at low temperature were inspected,second,the optimal conditions of mixed liquor recycle ratio and sludge recycle ratio for running were obtained under analysis on different parameter values,results were 100% and 100% respectively,then the control of other parameters were also given a brief introduction,finally,the overall running efficiency of the process was analyzed,and good results were obtained.A+A2/O process was proved for better nitrogen and phosphorus removal. |
| Keywords: | A+A2/O process nitrogen and phosphorus removal low temperature mixed liquor recycle ratio sludge recycle ratio sludge load dissolved oxygen sludge retention time |
