摘要

A novel process for a simultaneous removal of ammonia and organics was developed on the basis of ion exchange and biological reactions. From batch experiments, it was found out that NH_4~+ could be removed effectively by combining cation exchange and biological nitrification showing 0.98 mg N/m~2·s of a maximum flux. On the other hand, the removal of NO_3 was 3.5 times faster than NH_4~+ and the maximum flux was calculated to be 3.4 mg N/m~2·s. The systems for NH_4~+ and NO3 removal were combined for establishing the IEBR process. When the process was operated in a continuous mode, approximately 95.8% of NH_4~+ was removed showing an average flux of 0.22 mg N/m~2·s. The removal efficiency of total nitrogen was calculated as 94.5% whereas that of organics was 99.5%. It was concluded that the IEBR process would be effectively used for a simultaneous removal of NH_4~+ and organics.
