Method and apparatus for treating wastewater containing ammoniacal nitrogen |
| abstract |
(57) [Summary] [Purpose] It is a by-product that is problematic when removing ammoniacal nitrogen in wastewater by adding ozone to wastewater containing ammoniacal nitrogen in the presence of bromide ions. Suppress the formation of nitrate nitrogen and BrO 3 − . [Structure] A portion of the treated water from which ammonia nitrogen has been removed after ozone addition is circulated and mixed with the ammonia nitrogen-containing wastewater before ozone addition, while ozone is added to the ammonia nitrogen-containing wastewater. For example, a mixing tank 6 is interposed in an inlet pipe 4 through which raw water flows, and treated water flowing in a discharge pipe 8 is returned to the return pipe 1. 0 to circulate in the mixing tank 6. |
