| titleOfInvention | Method for treating wastewater containing nitrate nitrogen and ammonia nitrogen |
| abstract | (57) [Summary] [Structure] Nitrate nitrogen in wastewater containing nitrate nitrogen and ammonia nitrogen is reduced to nitrite nitrogen or nitrogen gas by contacting with metal that generates hydrogen in water, Treatment of wastewater containing nitrate nitrogen and ammonia nitrogen, characterized in that after the eluted metal is removed by softening treatment, the produced nitrite nitrogen and ammonia nitrogen are reacted in the presence of a catalyst and converted into nitrogen. Method. [Effect] According to the method of the present invention, nitrate nitrogen in waste water containing nitrate nitrogen and ammonia nitrogen at the same time is reduced to nitrite nitrogen or nitrogen gas at a low temperature using a metal that generates hydrogen in water in advance. However, the metal eluted at this time is removed by a softening treatment, and by combining the steps of converting to nitrogen by the catalytic reaction of ammonia nitrogen and nitrous nitrite, the nitrate nitrogen and ammonia nitrogen in the wastewater can be treated under mild conditions. It can be decomposed efficiently. |
