摘　　要：中置曝气生物滤池(BAF)挂膜方式的研究较多,但启动水源为混凝沉淀出水的研究鲜有报道,实验就中置BAF进水水源为混凝沉淀出水的2种挂膜方式做了研究,并对此作了比较。结果表明,由于待滤水和漂浮陶粒自由扰动特性的缘由,中置BAF在自然状态下挂膜较难成功,42 d后氨氮去除率仅为20.1%;而采用接种挂膜方式,在平均水温为16.7℃时仅需17 d就可挂膜成功,即氨氮的去除率达到并稳定在60%以上;与自然挂膜相比,接种挂膜大大缩短了挂膜周期,在工程生产上具有实际意义。There are many studies on forming film in biological aeration filter （BAF）, but the source of coagulation sedimentation effluent is rarely reported. Two kinds of forming film in BAF were briefly introduced here and compared. The results showed that precipitate of effluent and floating haydite characteristic made it hard for mid-positioned BAF to form film naturally, and ammonia removal rate was only 20.1% in 42 days. Inoculation method was useful, and the entire startup process took 17 days when the average water temperature was 16.7 ℃, i.e., the removal rate of ammonia reached more than 60%. Compared with natural method, inoculation method shortened the cycles of hanging film and held great promise in practical application.
