摘要
研究了生物滤池处理城市污水的性能特点,结果表明:厌氧-好氧生物滤池去除城市污水中的CODCr、SS和NH4+-N等具有较好的效果,当进水CODCr、SS和NH4+-N分别为23、112mg/L和56mg/L时,水力停留时间8h,曝气强度在0·5~0·6L/(m2·s)时,CODCr、SS和NH4+-N的去除率分别在90%、80%和75%以上。
Characteristics of anaerobic-aerobic biological filter(AABF) were studied to treat municipal wastewater in a pilot scale experiment.The experimental results showed that AABF had high efficiencies to remove organic pollutants,such as COD_ Cr ,SS and NH^+_4-N in municipal watewater.The removel rates of COD_ Cr ,SS and NH^+_4-N are over 90%,80% and 75% respectively,when influent COD_ Cr ,SS and NH^+_4-N are 234 mg/L,112 mg/L and 56 mg/L,hydraulic retention time is 8 h,and aerated intensity is in the range of 0.5～0.6 L/(m^2·s).
