The invention relates to a microwave photocatalysis integrated treatment method for a printing and dyeing sludge. The method comprises the steps of S1, adding 0.01-2parts by weight of photocatalyst, 1-5 parts of extracting agent, 1-10 parts by weight of electromagnetic wave absorber, 2-30 parts of alkaline curing agent and 0.1-5 parts of heavy metal curing agent into 100 parts by weight of the printing and dyeing sludge; S2, evenly mixing the printing and dyeing sludge with the added photocatalyst, an extracting agent, the electromagnetic wave absorber, a binder and the heavy metal curing agent; S3, treating the mixed printing and dyeing sludge in the step 2 into particles; S4, putting the sludge particles into a microwave oven for integrated treatment, and recycling exhaust generated in the treatment process. The microwave photocatalysis integrated treatment method for the printing and dyeing sludge has the advantages of energy conservation and high efficiency, even heating, degradation of organics, curing o
