摘要
采用以活性炭和沸石为组合滤料的曝气生物滤池处理人工景观水体，研究了不同污染程度（低、中、重）进水、水力停留时间及气水比对处理效果的影响。结果表明，在水温为21～33℃、水力停留时间为40min、气水比为1：1的条件下，对COD和NH4^＋ -N的去除具有较强的耐冲击负荷能力和良好的效果；过大或过小的水力停留时间和气水比均影响活性炭-沸石曝气生物滤池的处理效果。
The biological aerated filter （BAF） with activated carbon and zeolite media was adopted to treat artificial landscape water. The influence of influent with different degrees of pollution （low, medium and heavy）, hydraulic retention time （HRT） and air/water ratio on the performance of the BAF was studied. The results showed that under the conditions of temperature 21 to 33℃, HRT 40 rain and air/water ratio 1 ： 1, the process has strong resistance to shock loading and good and stable treatment effect. Larger or smaller HRT and air/water ratio were unsuitable for treatment effect of the BAF with activated carbon and zeolite media.
