| 摘 要： | 文章以南方某污水处理厂的实际运行情况为例,介绍了A-A2/O工艺在处理低碳源城市污水的效果。运行结果表明,工艺对BOD5、COD、SS的去除效果良好,达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。对于氮磷去除,出水NH4-N<0.5mg/L,TN<15mg/L,TP<1.5mg/L,但TN平均去除率只有45%左右;TP大多数的去除率在30%～50%之间。造成这种结果的主要原因是碳源不足。为提高除磷脱氮效果,采取了投加PAC来辅助除磷,并提出了进一步的改进措施,供同行参考。

| Abstract: | Based on practical running data of a wastewater treatment plant, nitrogen and phosphorus removal effect of A-A2/O process on treating urban wastewater with low carbon was studied. Results showed that the process was efficient in removal of BOD5, COD and SS and satisfactory to Grade A of national discharge standard of GB18918-2002. Effluent concentration of NH4-N, TN and TP were less than 0.5mg/L, 15mg/L and 1.5mg/L respectively, with removal efficiency of TN and TP only 45% and 30~50% due to no enough carbo... |
