摘　　要： 采用立体多孔高分子材料载体,SBR-三相流化床生物膜法处理人工合成污水。结果表明:在曝气4 h,停曝搅拌1.5 h,静沉0.5 h,闲置0.5 h的工艺条件下,系统的平均污泥产率系数为0.089 gMLSS/gCOD,COD、氨氮、总氮的去除率分别为90%、95%、70%以上;对磷的去除率在28%左右。试验还采用光学显微镜和扫描电子显微镜对载体内外的菌群分布进行了分析。 A kind of porous carrier made of polyamoniaester was used in this process. The optimal condition for each cycle was ： 4 h of aeration time; 1.5 h of stir without aration time; 0.5 h of deposition time and 0.5 h of leaving unused time. Under these conditions, the average sludge production was 0.089 gMLSS/gCOD, The removal rate of COD was above 90 %, the removal rate of NH4^＋-N and TN were above 90 % and 70 %, respectively. The removal rate of TP was only about 28 %
