Abstract
PURPOSE: To reduce nitric and nitrous acid contents in finally disposed water, by returning a part of disposed water from a reaeration vessel to a denitrificating vessel in a disposer for nitrogen-containing water.
CONSTITUTION: Nitrogen-containing water is nitrificated at first vessel 2, and denitrificated by injection of ethanol or the like in the second vessel 3. The denitrificated water is then aerated in the third vessel 4. In this process, the disposed water from the third vessel 4 is carried through a line 9 to the second vessel 3. The water returned to the second vessel 3 is reductively denitrificated again. Consequently, nitric and nitrous acid contents in the finally disposed water are remarkably reduced, even in case where the finally disposed water contains nitric or nitrous nitrogen contaminants.
