Embodiment 1
[0032] A, crush and grind 90 parts of waste glass with a mass component number, pass through a 200-mesh sieve, add waste incineration fly ash with a mass component number of 60 while stirring at room temperature at a speed of 20-30 r / min, and add Foaming agent CaCO 3 0.5 parts, continuously stirred and mixed to form a uniform mixture of fly ash + glass powder.
[0033] B. Add 40 parts of domestic waste leachate to the powdery mixture obtained in step A at room temperature while stirring at a speed of 20-30 r / min, and continuously stir and mix to form a uniform mortar mixture.
[0034] C. Granulate the mortar mixture formed in B to make 0.5~1cm pellets. Then put the formed pellets into the muffle furnace for roasting. Control the temperature rise rate of the muffle furnace to 5°C / min, and the temperature rises to 130°C, so that the balls are fully dried and preheated before firing. Raise the temperature at 5°C / min to the calcination temperature of 900°C, and keep the temper...
Embodiment 2
[0039] A. Break and grind 40 parts of waste glass with a mass component number, pass through a 200-mesh sieve, and add waste incineration fly ash with a mass component number of 60 while stirring at room temperature at a speed of 20-30 r / min, and add foaming Agent Na 2 CO 3 5 parts, mixed with continuous stirring to form a uniform fly ash + glass powder mixture.
[0040] B. Add 40 parts of domestic waste leachate to the powdery mixture obtained in step A at room temperature while stirring at a speed of 20-30 r / min, and continuously stir and mix to form a uniform mortar mixture.
[0041] C. Granulate the mortar mixture formed in B to make 0.5~1cm pellets. Then put the formed pellets into the muffle furnace for roasting. Control the temperature rise rate of the muffle furnace to 5°C / min, and the temperature rises to 120°C, so that the balls are fully dried and preheated before roasting. Raise the temperature at 8°C / min to the calcination temperature of 1000°C, and keep the ...
Embodiment 3
[0046] A. Break and grind 80 parts of waste glass with a mass component number, pass through a 200-mesh sieve, and add waste incineration fly ash with a mass component number of 20 while stirring at room temperature at a speed of 20-30 r / min, and add foaming CaCO 3 0.5 parts, continuously stirred and mixed to form a uniform mixture of fly ash + glass powder.
[0047] B. Add 60 parts of domestic waste leachate to the powdery mixture obtained in step A at room temperature while stirring at a speed of 20-30 r / min, and continuously stir and mix to form a uniform mortar mixture.
[0048] C. Granulate the mortar mixture formed in B to make 0.5~1cm pellets. Then put the formed pellets into the muffle furnace for roasting. Control the temperature rise rate of the muffle furnace to 3°C / min, and the temperature rises to 125°C, so that the balls are fully dried and preheated before firing. Raise the temperature at 10°C / min to the calcination temperature of 1200°C, and keep it for 1h....
