Abstract

5 kinds of aerobic denitrification strains were screened and put into the MBR to make an EMBR. Aerobic denitrification were studied to treat the high NH₄ ⁺-N wastewater treatment by the two MBRs (EMBR and common MBR). The result showed that the aerobic denitrification in MBR tank played a main role in removing the nitrogen at aerobic condition and the nitrogen removal efficiency was high to 93% in EMBR. The main pollution such as COD was also studied in the two MBRs. As a result, there had a good removal to the pollutions, in which the microorganisms played a greater role than membrane. The monitoring result indicated that the effluent quality of the MBR was better than the water quality standard for miscellaneous water consumption and scenic environment use (GB/T 18921- 2002), and the effluent could be totally used for irrigation.
