中文摘要	An integrative biofilm reactor was designed to treat domestic wastewater for biological nitrogen and phosphorus removal. The effects of the hydraulic retention time (HRT) and the media on the nitrogen and phosphorus removal were studied for continual treatment of domestic wastewater continuously in an integrated biofilm reactor. The nitrogen removal is analyzed based on the variety of the microbe community. The results indicate that media characteristics significantly impact the nitrogen and phosphorus removal. For HRT = 9 h, the total nitrogen removal rate was 68.9% in the reactor using B4 media. The HRT in the aerobic zone is the primary parameter limiting the nitrogen removal. The media affects the A/O microenvironment, producing simultaneous nitrifying and denitrifying in the aerobic zone.
