1. the preparation method of a compound ozone oxidation solid catalyst is characterized in that, may further comprise the steps:

  • the nitrate of A1, iron, manganese, nickel, copper was by 2;

    1;

    1;

    after 2 the mixed in molar ratio, be mixed with percentage by weight and be 10% active component salting liquid;

    A2, be the high-strength porous haydite of 4~

    10mm, clean that using percentage by weight afterwards is rare nitric acid dipping 1.5h of 13%, cleans oven dry again with distilled water with the NaOH solution of percentage by weight 8% with particle diameter;

    In the active component salting liquid that A3, the high-strength porous haydite that will dry configure above impregnated in, and flooded 7 hours, during stir for several times;

    With solution evaporation, drying, 850 ℃

    of following roasting 2.5h promptly make the finished product solid catalyst in muffle furnace then.
