Popis: Taking the smelting waste residue of arsenic plant I and II and the contaminated soil around them as the research object, the solidification/stabilization tests of the four pollutants were carried out with TY-Z, A, B and C agents. The test results show that the cost and solidification/stabilization effect of the new agent TY-Z are better than those of the other three agents, and the toxicity leaching amount of TY-Z is much lower than the standard for pollution control on the security landfill site for hazardous wastes(GB18598-2001). Through the phase analysis, microscopic morphology analysis and morphological analysis of As pollutants, the results show that the solidification/stabilization effect of the new agent TY-Z is better than that of the other three agents.
