摘　　要：硝化菌的挂膜问题一直是氨气处理中较难解决的问题,采用生物滴滤池对天然斜发沸石和多面空心小球进行硝化 菌挂膜研究。实验表明沸石在15天左右就能基本完成硝化菌的挂膜启动,而小球则要20天才能完成;随着COD:NH3-N降 低,各载体生物膜量有所减少;同时,生物膜内生物相也相应改变。biofilm colonization is a very important problem in the removal of waste gas.In this paper,TBAB packed with zeolite and polypropylene multi-face ball are used to remove ammonia. Two methods ,sludge circling and culture trickling, are applied in this process..It is take about 15days that the biofilm becames mature on the face of zeolite but more than 20days on polypropylene.With the drop of COD:NH3-N,the biomass is reduced,and also the microorganisms change accordingly.
