摘　　要：采用曝气生物滤池(BAF)处理印花废水,重点考察了水力停留时间(HRT)、C/N值、气水比对其脱氮效果的影响。结果表明:在HRT为4 h、C/N值为2、气水比为5∶1的条件下,BAF可达到最佳脱氮效果,对TN、NH 4+-N的去除率分别达到50%、90%以上。Biological aerated filter （BAF） was used to treat the textile printing wastewater, and the influence of HRT, C/N ratio, gas-water ratio on the nitrogen removal were mainly investigated. The results show that the optimal nitrogen removal efficiency can be achieved under the conditions of HRT 4 h, C/N ratio 2 and gas-water ratio 5 ： 1, and the removal rates of TN and NH4＋ - N are more than 50% and 90% respectively.
