By using a semi-suspended bio-carrier fabricated with 3D printing tech- Semi-suspended bio-carrier nique, an obvious DO gradient was gradually created within the biofilm, which demonstrated that a coupling Microbial community anaerobic-aerobic biofilm was successfully established on the surface of bio-carriers. The results of metagenomic 16S metagenomic analysis analysis revealed that the microbial community on the bio-carriers experienced a continuous succession in its Multi-habitat structure and dominant species along with the operational time
