METHOD TO REMOVE AMMONIA FROM MINE DEPRESSURIZATION WATER |
| 摘要 |
The invention is directed to a process for removing ammonia from mine depressurization water involving introducing the water into a tank or collection pond; injecting a sufficient amount of an oxidizing gas into the water to yield aerated water; and holding the aerated water within the tank or collection pond for a pre-determined residence time to perform air-stripping on the aerated water to facilitate the volatilization of ammonia; nitrification to convert ammonia into nitrate and nitrite; or both. |
