The environmental processing function of calcium hydroxide
1, as a strong alkaline reagents and acid wastewater and heavy metal wastewater, acid wastewater be neutral.
2, to absorb the SO2 in boiler flue gas, make the discharge flue gas flow comply with environmental standards.
3, colloid particles in the wastewater can help the setting, and as a particle and weight gain agent, accelerate the separation of insoluble substance.
4, can effectively remove phosphoric acid root, root and fluorine ion anion sulfate.
5, Can destroy the complexing agent such as amino sulfonic acid root or rock mixture on the combination of some metal ions.
6, by adjusting the PH stability of emulsion wastewater has the effect of demulsification.
7, the effect of wastewater treatment, waste water treatment of conventional alkaline reagents, compared with content of 30% caustic soda lye, caustic soda lye price per ton and per ton calcium hydroxide powder, but look from the treatment effect, to take the calcium hydroxide powder price is less than the 50% of sodium hydroxide lye, look from the coagulation decolorization effect is superior to sodium hydroxide lye, is recognized as the preferred alkaline neutralization agent all over the world.
8, Ca (OH) 2 fineness Super hydrated lime 95% 325 mesh (45 um), or environmental flue gas desulfurization (power plants, incinerator), coating, paint, non-ferrous metal smelting, burning paper industry with medicine such as antacids, astringent, carbon water softener, etc.
