Embodiment 1
[0022] A sintered synthetic slag, comprising the following raw materials in weight percentage: 10% high-adsorption filler, 25% CaO, 10% SiO 2 , 8% MgO, 6-10% FeO, 1% CaF 2 , 0.01% of P, 5% of water, 3% of aluminum and iron balls, and the balance is impurities;
[0023] The sintered synthetic slag is made by the following method:
[0024] CaO and SiO 2 Grind into powder, then add water, MgO, FeO, CaF in sequence 2 , P, high-adsorption filler, mixed uniformly and made into a spherical shape, the particle size is controlled to be 50mm, and then mixed with aluminum-iron balls and transferred to a high-temperature furnace for firing. The temperature of the high-temperature furnace is controlled at 1200 ° C, and the firing time is 3 hours. , to obtain the sintered synthetic slag.
[0025] High adsorption packing is made by the following methods:
[0026] Step (1) After calcining illite at 450°C for 1 hour, add it to a 10% sodium chloride solution by mass fraction, heat in a wat...
