Embodiment 1
[0039] (1) Zeolite modification
[0040] Pour the natural zeolite block into a jaw crusher for crushing, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain zeolite with different particle sizes, and finally pass it through an 80-mesh sieve for later use. Weigh a certain amount of zeolite passing through an 80-mesh sieve, put it into an oven, and calcine it at a temperature of 250° C. After 5 hours, take it out and put it in a desiccator to cool to room temperature, and seal it for future use.
[0041] (2) Calcination of dolomite
[0042] Pour the natural dolomite minerals into the jaw crusher for crushing, then calcinate at 1600°C for 5 hours to form calcined dolomite, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain dolomite with different particle sizes, passing through 80 mesh Sift for later use.

[0048] (1) Zeolite modification
[0049] Pour the natural zeolite block into a jaw crusher for crushing, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain zeolite with different particle sizes, and finally pass through a 2000-mesh sieve for later use. Weigh a certain amount of zeolite passing through a 2000-mesh sieve, put it into an oven, and calcine it at a temperature of 800 ° C. After 2 hours, take it out and put it in a desiccator to cool to room temperature, and seal it for future use.
[0050] (2) Calcination of dolomite
[0051] Pour natural dolomite minerals into a jaw crusher for crushing, then calcinate at 700°C for 1.5 hours to form calcined dolomite, then use a disc mill to further grind it, and sieve it with a vibrating sieve to obtain dolomite with different particle sizes. After the mesh sieve, it is ready for use.

[0057] (1) Zeolite modification
[0058] Pour the natural zeolite block into a jaw crusher for crushing, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain zeolite with different particle sizes, and finally pass it through a 1800-mesh sieve for later use. Prepare a hydrochloric acid solution with a concentration of 20 mol / L at room temperature, weigh a certain mass of 1800-mesh zeolite with a liquid-solid ratio of 3:1, soak it in the prepared 20 mol / L hydrochloric acid solution and stir it at a constant speed for 1 h, After standing for 5 hours, filter, wash, dry, and place in a desiccator for later use.
[0059] (2) Calcination of dolomite
[0060] Pour natural dolomite minerals into a jaw crusher for crushing, then calcinate at 800°C for 4.5 hours to form calcined dolomite, then use a disc mill to further grind, sieve with a vibrating sieve to obtain dolomite with different particle sizes, pass 1800 After the mesh sieve, it is ready for u...
