The invention relates to a preparation method of a copper-containing waste residue solid ozone composite denitrification agent, and belongs to the field of preparation of denitrification agents. For the problem that the chemical method and biological method have high cost and high investment and the biological method has relatively poor treatment effect on ammonia nitrogen in the existing treatment process of high concentration ammonia nitrogen wastewater, the ultrafine dispersion modified copper-containing residue is prepared by milling and modifying the copper-containing waste residue, then a copper-containing denitrification agent is prepared by synthesis, composite denitrification agent particles are prepared by freezing the copper-containing denitrification agent in ozone gas, a metal ammonia complex is formed by copper and NH3.H2O, and meanwhile, under the catalysis of ozone, the high concentration waste water treatment efficiency is improved, and the removal efficiency of ammonia nitrogen is as high as
