摘要
介绍了颗粒填料曝气生物滤池应用于啤酒废水的研究 .我们得到了在停留时间 8h、气水比为 6∶1时 ,CODcr(污物 )去除率达到 91% ;在气水比为 6∶1时 ,停留时间为 4h ,氨氮去除率达到 97.2 % .
This article introduces the study on Biological Aerated Filter (BAF) applying in beer wastewater.We obtain COD cr (dirt) removal ratio is 91% when the residence time is 8 hours and gas-water ratio is 6∶1 and ammonia nitrogen removal ratio is 97.2% when the residence time is 4 h and gas-water ratio is 6∶1.We also have studied the effect of the removal ratio of COD cr and ammonia nitrogen by different gas-water ratio and residence time.
