In this study, the alternating 3-stage biological aerated filter system with the brush as the filler was proposed for campus sewage treatment and the biofilm formation process was researched. Adopting the four-stage inoculated biofilm formation method, the treatment effects of the 3 filter columns respectively lasted 23d, 20d, 23d to reach stable. After the attached biofilm grew steadily, the effluent COD concentration was between 45 mg/L and 95 mg/L, and the removal efficiency was 77%~85%. The effluent NH4+-N concentration of 1st and 3rd filter columns was 11~25 mg/L, and the removal efficiency was 47%~67%; while the effluent NH4+-N concentration of 2nd filter column was 8 ~19 mg/L, the removal efficiency was 64%~ 78%.
