Cross-linking curing treatment method for saline-alkali-containing slag

The invention discloses a cross-linking curing treatment method for saline-alkali-containing slag, which belongs to the alkaline slag waste treatment technology, and comprises the following steps: adding water into saline-alkali-containing slag and loess, mixing and stirring to obtain a slag slurry mixture; mixing and reacting polyethylene glycol, chlorinated paraffin and toluene diisocynate to obtain a soil cross-linking agent; and mixing the soil cross-linking agent and the slag slurry mixture in proportion, adding a catalyst, stirring, extruding to remove moisture, and air-drying to obtain a cross-linked solidified body. By utilizing the treatment method for cross-linking and curing the alkaline residue waste, the use of cement, lime and the like in a traditional curing method can be reduced, the method has the characteristics of simple technological process, energy conservation, environmental protection, safety, reliability and the like, the pH value of the treated alkaline residue can be controlled betwe
