A preparation method for a molecular sieve-multiple oxide composite integral extrusion type denitration catalyst includes constructing an organic structure coating on the surface of a metal ion-exchanged molecular sieves and synchronously adding multiple oxide components, thus obtaining an ion-exchanged molecular sieve-multiple oxide composite denitration catalyst active component; and then mixing, kneading into paste, staling, carrying out integral extrusion forming, drying, and calcining, thus obtaining the integral extrusion type denitration catalyst. The molecular sieve-multiple oxide composite integral extraction type denitration catalyst has a denitration efficiency more than 80% at the temperature ranging from 250&#xb0; C. to 420&#xb0; C. in the presence of 10% steam and 500 ppm sulfuric dioxide.
