The phosphated slag belongs to hazardous waste, is acidic in national hazardous waste records and mainly contains iron, zinc and phosphate radical; meanwhile, according to the type of the used phosphating solution, the phosphating solution also contains a certain amount of calcium, potassium, nickel and other ions. If the phosphorization slag is directly discharged into soil, substances such as phosphate in the phosphorization slag can generate soil acidification reaction or other reactions through weathering, rain and snow leaching and erosion of the runoff on the earth surface, and some trace metal substances can be accumulated in the soil. If the phosphorization slag enters rivers, lakes or oceans along with natural rainfall or surface runoff, the surface water is polluted, and the excessive phosphorus can cause water eutrophication; if the runoff permeates underground along the surface of the land, the groundwater can be polluted.
