| 摘 要： | 通过改变CASS工艺的运行方式。采用好氧脉冲曝气，研究FND—CASS工艺对城市生活污水脱氮除磷效果的影响。试验结果表明：好氧脉冲曝气对系统的脱氮除磷有显著影响。通过改变好氧脉冲曝气方式，发现好氧脉冲曝气对COD和NH3－N的去除有一定影响，对TN和TP的去除有显著影响。试验表明，本工艺的最佳好氧脉冲曝气方式为5—5（min），COD、NH3-N、TN和TP的去除率分别为89．32％、82．43％、80．52％和80．44％。

| Abstract: | This paper studies the treated effect of FND -CASS process on nitrogen and phosphorus removal by altering the performance way of CASS process. The test results are showed as follows ： Pulsant aeration has much impact on nitrogen and phos- phorus removal. When changing the type of pulsant aeration, we found that pulsant aeration has some effect on organic substance removal and ammoniacal nitriticafion while it has much effect on nitrogen and phosphorus removal. The optimal pulsant aeration is 5 -5（ minutes）, the removal ratio of COD, NH3 - N, TN and TP are 89. 32% , 82. 43% , 80. 52% and 80.44% respectively. |
