Embodiment 1
[0026] According to the total mass percentage of the chloride ion remover, calcium oxide accounts for 75%, sodium metaaluminate accounts for 25%, and they are mixed to form calcium oxide inorganic chloride ion remover. A certain chemical wastewater has a chloride ion concentration of 35,000 mg / L, and the prepared calcium oxide inorganic chloride ion remover is added to the wastewater at a mass ratio of 2%, and stirred for 30 minutes. After static separation and separation, the supernatant is chlorine-removed wastewater, and the removal rate of chloride ions is 99.9%.
Embodiment 2
[0028] According to the total mass percentage of the chloride ion remover, calcium oxide accounts for 70%, and sodium metaaluminate accounts for 30%, which are mixed to form calcium oxide inorganic chloride ion remover. A certain chemical wastewater has a chloride ion concentration of 35000mg / L, and the prepared calcium oxide inorganic chloride ion remover is added to the wastewater at a mass ratio of 3.5%, and stirred for 20 minutes. After static separation and separation, the supernatant is chlorine-removed wastewater, and the removal rate of chloride ions is 99.9%.
Embodiment 3
[0030] According to the total mass percentage of the chloride ion remover, calcium oxide accounts for 80%, and sodium metaaluminate accounts for 20%, which are mixed to form calcium oxide inorganic chloride ion remover. A certain chemical wastewater has a chloride ion concentration of 35,000 mg / L, and the prepared calcium oxide inorganic chloride ion remover is added to the wastewater at a mass ratio of 5%, and stirred for 10 minutes. After static separation and separation, the supernatant is chlorine-removed wastewater, and the removal rate of chloride ions is 99.9%.
