The ultra-low emission production method of refined vanadium includes the following steps: grinding and dispersing the ammonium metavanadate filter cake into powder or small particle size, and sintering continuously in a sintering kiln at 100-125°C; On the premise of bag dust removal, the filter residue of bag dust removal is returned to the sintering kiln; the waste gas after bag dust removal is cooled once and then enters a cooling room for secondary cooling; the waste gas after twice cooling is sprayed three times to complete the waste gas Separation of ammonia gas; ammonia-containing wastewater used to absorb ammonia gas in waste gas is injected into neutralized water containing sulfuric acid for ammonia removal. The present invention has the advantages of being able to realize ultra-low emission and the like.
