| titleOfInvention | Method for removing ammonia and / or ammonium ions from wastewater |
| abstract | (57) [Problem] To provide a method for removing ammonia and / or ammonium ions in wastewater. SOLUTION: When adding a magnesium compound and phosphoric acid or a phosphate for the purpose of removing ammonia and / or ammonium ions in the wastewater, the wastewater is added in a molar ratio to the total amount of the ammonia or ammonium ions to be removed. The ratio of the magnesium compound in terms of magnesium ion to the phosphoric acid or phosphate in terms of phosphate ion is such that Mg 2+ is in excess of NH 4 + : Mg 2+ = 1: 1 and NH 4 + : PO 4 3 - = 1: after adding as PO 4 3- is excessive than 1, the PH of the waste water from 7.5 to 11.5 And forming a precipitate of sparingly soluble magnesium ammonium phosphate by adjusting the amount of ammonia and / or ammonium ions in waste water. |
