| Abstract: | Adopted activated Mgo method to reduce fluoride concentration of groundwater in high fluoride area,the paper studied mechanism of removing fluorine,optimum throwing quantity and influencing factors.The result indicated that fluoride concentration was less than 1 mg/L when 0.45 g activated Mgo was put into 300 ml water sample whose fluorine concentration was 1.75 mg/L.The best treatment effect of activated MgO method was on condition that the water was pH=4.5～9 condition,the temperature of 20～40 ℃ and 30 min reaction time. |
