Embodiment 1
[0053] 1) Crushing 50kg of waste slag, grinding it in a ball mill, with a particle size of 10 μm, and putting the waste slag into the furnace from the feed port after aging;
[0054] 2) Put 100kg of industrial waste acid into the feed port, then mix it with industrial wastewater and waste alkali, lower the agitator and pH meter until the pH value is adjusted to 5.5;
[0055] 3) Turn on the power so that the temperature in the cavity is 100°C and the pressure is controlled at 4.6MPa;
[0056] 4) After the reaction is over, the bottom valve is opened, and the material flows out from the bottom;
[0057] 5) After filtering and drying the material, calcining for 2 hours at a calcining temperature of 500°C;
[0058] 6) Take two adsorption products, both of which have a mass of 50 g, and put them into CuSO with a volume of 1 L and a concentration of 1 mol / L respectively. 4 and 1mol / L FeCl 3 In the standard solution, let stand for 60min;
[0059] 7) After filtering the solution, ...
