摘　　要：对新型接种挂膜与逐渐增加流量的自然挂膜两种方式进行了比较和分析。结果表明,挂膜后期前者的COD去除率可达90.36%,NH3-N去除率可达70.14%,后者则为87.69%和34.67%。前者生物膜生长情况好于后者,生物膜的成熟期缩短了4d;采用两级反应柱可以增加曝气生物滤池对NH3-N的去除效果。In the test was carried out the comparison of both ways of new biofilm growing by inculation and natural biofilm growing by gradually increasing flow to seek for suitable biofilm growing way for biological aerated filter and shorten the biofilm growing time. The determination and analysis ofbiofilm growing condition and organics and ammonia nitrogen removal by the biological filter were done for various biofilm growing methods. The results showed that, in the late of biofilm growing, the former＇s COD removal rate could reach to 90.36%; NH3-N removal rate could reach to 70.14%; the latter＇s both removal rates could reach to 87.69% and 34.67% respectively; the former＇s growing condition was better than the latter; the mature term of the biofilm shortened 4d; adopting two stage reaction column could improve the NH3-N removal effect by biological filter.
