| titleOfInvention | Method and apparatus for biological denitrification of water |
| abstract | PROBLEM TO BE SOLVED: To reduce the utilization rate of a supplied hydrogen gas when treating nitrate or nitrite nitrogen-containing water having a low organic substance concentration by a biological denitrification method of supplying hydrogen gas as a hydrogen donor. To provide a method that can be denitrified efficiently, inexpensively and efficiently. SOLUTION: The organic matter concentration is low and nitrate nitrogen and / or Alternatively, in a method of biologically denitrifying water containing nitrite nitrogen using hydrogen gas as a hydrogen donor, the liquid to be treated is continuously flowed into the cathode portion and the anode portion of the diaphragm electrolytic cell 3. After the hydrogen gas generated at the cathode portion is dissolved or mixed in the liquid to be treated in the diaphragm electrolysis tank 3, the hydrogen gas is passed through the raw water inlet of the denitrification reaction tank 1, and the oxygen gas generated at the anode portion is aerated in the aeration tank. 2 and the effluent of the anode part is p Return to the H adjustment tank 9. |
