The invention discloses a denitrification fluorine-fixing agent for comprehensive treatment of secondary aluminum ash and a preparation method thereof, the denitrification fluorine-fixing agent is composed of, by weight, 5-25% of calcium peroxide, 55-75% of kaolin and 5-20% of sodium carbonate, and the sodium carbonate is composed of, by weight, 10-30% of ultrafine powder and 70-90% of coarse powder. The denitrification fluorine-fixing agent contains sodium carbonate with different granularities, after the sodium carbonate coarse powder and the aluminum ash are mixed and stirred, the sodium carbonate is decomposed into sodium oxide at high temperature, the sodium oxide can adjust the alkali ratio of a calcination system, and due to the fact that the content of aluminum oxide in the calcination process is dynamically changed, the sodium oxide gradually decomposed from the sodium carbonate can meet dynamic adjustment; wherein the sodium carbonate ultrafine powder can permeate into slits of ...
