【 摘 要 】

This paper used a stage aeration anaerobic fluidized bed membrane bioreactor (AFMBR), combined the advantages of membrane bioreactor (MBR) and anaerobic fluidized bed bioreactor (AFBR), put forward to add granular activated carbon (GAC) to make up for the deficiency of AFMBR process, and explored its impact on the process effect. At the same time, it was proposed to utilize the stage aeration to enhance the membrane flux, and to increase the residence time of organic pollutants in the facultative environment through the fluidized bed membrane bioreactor to improve the removal characteristics of organic pollutants in landfill leachate. The influence of aeration rate on the process effect was also investigated. Finally, the relationship between temperature and AFMBR treatment effect was briefly analyzed.
