摘　　要：针对低浓度污水处理,在垂直流人工湿地理论基础上,并结合曝气生物滤池的特点,开发出了生态滤池,其由下行池和上行池组成。利用该滤池处理COD均值为158.13 mg/L的低浓度生活污水,在处理水量约为1.5 m3/d、水力负荷为60 L/(m2·h)、下行池气水比为1∶1、HRT为2 d的条件下,对COD、NH+4-N、TN和TP的平均去除率分别为83.8%、93.1%、52.9%和79.1%。说明该滤池对低浓度污水的处理效果较好。A reactor named ecological filter for low concentration wastewater treatment was devel- oped on the basis of vertical flow constructed wetland and biological aerated fiher （BAF）, which was made up of down-flow chamber and up-flow chamber. Low concentration wastewater with a mean COD concentration of 158.13 mg/L was treated by the filter. Under the conditions of treatment capacity of 1.5 m3/d, hydraulic loading of 60 L/（m2 · h）, gas-water ratio of 1 ： 1 and HRT of 2 d, the average removal rates of COD, NH4＋ - N, TN and TP were 83.8% , 93.1% , 52.9% and 79.1% respectively. The re- sults showed that the ecological filter had a good treatment efficiency of low concentration wastewater
