<P>PROBLEM TO BE SOLVED: To provide an apparatus for treating wastewater containing ammonium salt that can efficiently treat wastewater containing ammonium salt by increasing electric conductivity in a cation concentration chamber, and reducing power consumption of an electrodialyzer in the apparatus for treating wastewater containing ammonium salt by the electrodialyzer. <P>SOLUTION: The apparatus for treating wastewater containing ammonium salt is adapted to supply wastewater containing ammonium salt into a desalting chamber 18 of the electrodialyzer 10, to take out acid-containing water from an anion concentration chamber 17 and to take out ammonia water from a cation concentration chamber 19. The apparatus includes return lines 40, 44 returning ammonia water taken out of the cation concentration chamber 19, to the cation concentration chamber, and a carbon dioxide blow-in tank 41 blowing carbon dioxide into ammonia water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
