摘　　要：介绍了A2 /O脱氮除磷工艺的机理、特点及存在的问题 ,对A2 /O工艺进行了取消混合液回流的改良型试验研究。试验结果表明 ,取消混合液回流后 ,有机物和氮的去除效果同传统型的相当 ,而在同样条件下除磷效果较优。这表明将A2The mechanism, feature and existing problems of A 2/O process for P and N removal are presented and an improved process for which the recycling of mixed liquid was left out was researched experimentally. The results show that the removal of N and organic substances of the improved process are same as the former and the P removal of the new process is better under same operating circumstance. These mean that incorporation of the sludge circulation and the inner recycling of the A 2/O process into one exclusive recycling system will be feasible.
