The present invention provides a new treatment method for removing ammonia from ammonia-containing water, which can improve the removal rate of ammonia by using a predetermined catalyst. A method for treating an aqueous solution containing ammonia and nitrate ions, comprising reacting the aqueous solution in the presence of a catalyst at 100 to 300 ° C. and 0.1 to 8.6 MPa. The treatment method is selected from the group consisting of molybdenum, vanadium oxide, a combination thereof, and a molybdenum-vanadium composite oxide. [Selection figure] None |
