摘　　要：采用陶粒为滤料的曝气生物滤池处理生活污水,考察水力停留时间（HRT）、曝气量、pH值对处理效果的影响.实验结果表明,在水力停留时间为3~6 h时,对出水COD去除率可达83.7%~90%,对氨氮去除率可达85%以上;在曝气量为0.08~032 m3/h时,对出水COD去除率可达到83.4%~86.8%,出水氨氮最高去除率可达85.2%.pH值在6.57~8.72之间对COD、氨氮基本没有影响.曝气生物滤池处理的生活污水出水COD、氨氮均可达到国家二级出水的标准.Biological aerated filter（BAF）with ceramicite material are applied for domestic wastewater treatment.The effects of HRT,aeration and pH value on the treatment efficiency are investigated.The results show that when HRT is 3 to 6 h,the removal of COD and ammonia are 83.7%～90% and 85%;when ammonia is 0.08～0.32 m3/h,the removal of COD and ammonia are 83.4%～86.8% and 85.2%;the pH value varying in the range 6.57～8.72,has no effect on the removal of COD and ammonia in the research.The effluent wastewater quality can meet with second degree discharging standards after treatment.
