| titleOfInvention | Nitrite type nitrification-reactive sludge, production method therefor, production apparatus therefor, and waste water treatment method and waste water treatment apparatus |
| abstract | It is an object of the present invention to provide a nitrite type nitrification reaction sludge which has a low energy cost and can perform stable wastewater treatment over a long period of time, a production method and apparatus for the nitrification type nitrification reaction sludge, a wastewater treatment method and a wastewater treatment apparatus. An alkaline solution is added to the activated sludge 12 from the alkaline liquid tank 18 so that the pH of the activated sludge 12 containing ammonia oxidizing bacteria and nitrite oxidizing bacteria becomes 10 or more. As a result, the nitrite-oxidizing bacteria in the activated sludge 12 can be deactivated and the ammonia-oxidizing bacteria can be accumulated evenly. Thereby, the nitrification reaction of ammonia nitrogen is stopped at the stage of nitrite, and the supply amount of oxygen during the nitrification reaction and the supply amount of the hydrogen donor during the reduction reaction can be reduced. |
