Harmless treatment method for electroplating sludge

The invention belongs to the technical filed of environmental protection engineering and particularly relates to a harmless treatment method for electroplating sludge. The harmless treatment method comprises the following steps: the electroplating sludge is taken, certain amount of quicklime and flue gas desulfurization gypsum is added, crushed sufficiently and stirred uniformly, the mixture is left to stand for a period of time, and modified electroplating sludge is obtained; the modified electroplating sludge and fly ash are taken and stirred uniformly, a certain amount of a composite activator is added and stirred sufficiently again, and a mixture is obtained; an electroplating sludge test block is obtained in a pressure forming manner and cured in a room-temperature environment for 7-28 days, and a solidified electroplating sludge body is obtained. The harmless treatment method adopted for treating the electroplating sludge has the advantages of simple process, low cost, large electroplating sludge curing amount, small capacity increase and the like, meanwhile, the solidified electroplating sludge body obtained after treatment is highly corrosion-resistant, stable for a long time and low in heavy metal leaching toxicity, has certain compressive strength and can be taken as general solid waste to be subjected to landfill treatment.
