NITRATION TREATMENT METHOD FOR SEAWATER CONTAINING AMMONICAL NITROGEN

摘要

PURPOSE: To efficiently nitrate ammomiacal nitrogen in seawater. CONSTITUTION: The nitration capacity per unit volume of ammoniacal nitrogen in seawater can be increased eminently by using a filler in which immobilized microorganisms 5 are stuck or deposited on the surface of oyster shell 6 as a filler for treatment by catalytic aeration, and an enough nitration capacity is kept even at low water temperature.
