摘要：

The microorganism-attached activated carbon fluidized bed (MAACFB) process was applied to treat a real landfill leachate containing refractory organics and a high concentration of ammonium nitrogen. The MAACFB process consisted of two fluidized bed reactors in series: anaerobic and aerobic. The MAACFB process was found to be effective in treating the landfill leachate. The MAACFB process removed about 60 and 70% of refractory organics and nitrogen, respectively, from the landfill leachate simultaneously and steadily over more than 700 days of the operation period. A mass balance of the organics around the MAACFB process revealed that most of the removed organics may be biodegraded.
