摘　　要：采用陶粒、沸石、活性炭填料合理组合作为曝气生物滤池的填料对高校生活污水进行处理。研究了组合填料生物滤池生物膜的培养,不同水力负荷、容积负荷和气水比对污水处理效率的影响,以及该生物滤池对生活污水的处理效果。结果表明,采用组合填料生物滤池,接种挂膜培养周期为25 d,在水力负荷为2.5 m3/(m2·h),气水比3.5:1,组合填料生物滤池出水COD、BOD5、SS、NH3-N和色度平均值达到《城市污水再生利用城市杂用水水质》GB/T 18920-2002水质要求。As a filter medium, Ceramic, zeolite, activated carbon were combined to use for biological aerated filter in the treatment of campus domestic wastewater. The study focused on the start rule of the combined medium biological aerated filter. Meanwhile, different hydraulic load, load capacity and water ratio on the sewage treatment effect, and the treatment effect of biological aerated filter for domestic wastewater were studied. The results show that, the time needed for the start-up and film formation of combined medium biological aerated filter about 25 d. When the hydraulic load was 2.5 ma/（m2.h） , the water ratio was 3.5：1, combined medium biological aerated filter becomes more reasonable and suitable, achieving good results in practical operation, the average values of COD, BOD5, SS, NHa-N and Chrominanee reached the Standards for The reuse of urban recycling water-water quality standard for urban miscellaneous water consumption GB/T 18920-2002.
