摘要
对曝气生物滤池 (BAF)处理生活污水的工艺条件进行了系统试验 .研究表明 ,BAF工艺的主要影响因素依次是滤层高度、气水比、水力负荷和进水有机物浓度 ;得到的经验速度方程与Monod方程吻合 .在优化的工艺条件下 ,BOD负荷达 6～ 10kg/ (m3 ·d) ,BOD5去除率为 80 %～ 90 %,NH3 -N去除率为 80 %.
Systematic experiments on the technological conditions of the domestic sewerage treatment were done.The results show that the main influencing factors of Biological Aerated Filter(BAF) technology are the highness of fillers,the ratio of gas to liquid,the hydraulic loading and the influent organic concentration.The experiential velocity equation,which was gotten from the experiment,tallies with Monod equation.The optimal technological conditions for BAF process being determined,the organic loading of BOD,the removal of BOD and the removal of NH 3-N are 6～10 kg/(m 3·d),80%～90%,80%,respectively.
