Embodiment 1
[0026] A method for stabilizing and solidifying inorganic fluoride landfill hazardous waste, comprising the following steps:
[0027] (1) Add 5 parts by weight of calcium chloride solution to the broken hazardous waste to obtain mixture A;
[0028] (2) Add 10 parts by weight of cement to mixture A to obtain mixture B;
[0029] (3) Add 1 part by weight of 5% phosphoric acid solution to mixture B to obtain mixture C.
[0030] (4) After the mixture C has been cured and all indicators meet the entry standards for landfill hazardous waste, it will be landfilled.
Embodiment 2
[0032] A method for stabilizing and solidifying inorganic fluoride landfill hazardous waste, comprising the following steps:
[0033] (1) Add 10 parts by weight of calcium chloride solution to the broken hazardous waste to obtain mixture A;
[0034] (2) Add 20 parts by weight of cement in mixture A to obtain mixture B;
[0035] (3) Add 1 part by weight of 5% phosphoric acid solution to mixture B to obtain mixture C.
[0036] (4) After the mixture C has been cured and all indicators meet the entry standards for landfill hazardous waste, it will be landfilled.
Embodiment 3
[0038] A method for stabilizing and solidifying inorganic fluoride landfill hazardous waste, comprising the following steps:
[0039] (1) Add 60 parts by weight of calcium chloride solution to the broken hazardous waste to obtain mixture A;
[0040] (2) in mixture A, add the cement of 50 parts by weight to obtain mixture B;
[0041] (3) Add 12.5 parts by weight of phosphoric acid solution to mixture B to obtain mixture C.
