摘要
Abstract
The defluorinating effect of Ca(OH)2 and CaCl2 for reverse osmosis concentrat-ed water was investigated and the addition dose, optimal pH value and interference of chlo-ride ion in reverse osmosis concentrated water and sulfate ion on defluorination effect were studied. The experiment results indicated that when directly dosing 3000 mg/L of Ca (OH)2 or adjusting the pH>9 of the concentrated water and directly dosing 2000 mg/L of CaCl2, the content of fluoride in outlet water was below 10 mg/L, meeting the requirement of national standard for wastewater discharge.关键词
