The patent abstract shows that the invention discloses a curing and stabilizing agent and treatment method for screening humic soil in landfills. The agent includes: a gelling component, a heavy metal stabilization component, an organic matter passivation component, a pore regulation component, and a process adjustment component; the gelling component includes steel slag, fly ash, and calcium sulfoaluminate cement; the heavy metal stabilization component includes dicalcium phosphate and sodium sulfide; the organic matter passivation component includes potassium permanganate; the pore regulation component includes desulfurization gypsum and an air-entraining agent; the process adjustment component includes a polycarboxylic acid water-reducing agent and a triethanolamine early strength agent. This invention provides core strength through a steel slag-fly ash-calcium sulfoaluminate cement synergistic gelling system, fixes heavy metals using a phosphate-sodium sulfide dual stabilization mechanism, uses potassium permanganate to oxidize and passivate humic acid, and introduces desulfurization gypsum-air-entraining agent to adjust the pore structure. The agent of this invention can significantly enhance the mechanical performance of the solidified body, reduce permeability, and effectively inhibit the leaching of heavy metals and organic pollutants.
