摘　　要：在间歇曝气运行方式下对折流曝气生物滤池(BBAF)处理小城镇生活污水的效能进行了研究,考察了曝气/停曝时间对处理效果的影响。结果表明,在气水比为8∶1、曝气/停曝时间分别为1.5h/1h和1.25h/1.25h的条件下,当进水COD为53～275mg/L、TN为16.83～47.68mg/L、TP为1.58～3.75mg/L时,出水水质均能满足《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级B标准。曝气/停曝时间为1.25h/1.25h相对节能,可作为今后运行的主要工况。The efficiency of baffled biological aerated filter(BBAF)under intermittent aeration mode for domestic sewage treatment in small towns was studied,and the influence of aeration time/non-aeration time on the treatment effect was investigated. The results show that under the conditions of air/wastewater ratio of 8 ∶1,aeration time/non-aeration time of 1.5 h/1 h and 1.25 h/1.25 h,and when the influent COD,TN and TP are 53 to 275 mg/L,16.83 to 47.68 mg/L and 1.58 to 3.75 mg/L respectively,the effluent quality c...
