摘要
开发了一种新型曝气生物滤池--折流曝气生物滤池(BBAF),并考察了其对生活污水中COD、SS、氮、磷的去除效果.试验表明,BBAF对COD、SS的去除率在90%以上,对氨氮、总氮、总磷的平均去除率分别为74.0%、39.1%、46.5%,滤层纳污能力强,不易堵塞,反冲周期为7～8 d.
A new biological aerated filter—baffled biological aerated filter (BBAF) was (develo)-ped, and its removal efficiency for COD, SS, N and P was investigated. The experiment shows that the removal rate of COD and SS in BBAF is over 90%, and the removal rate of NH_4-N, TN, and TP is averaged at 74.0%, 39.1%, and 46.5% respectively; BBAF has large pollution-carrying capacity, and is uneasy to be blocked; its backwash cycle is 7-8 days.
