摘要

In our country, high fluoride containing groundwater is general. Now, there have been some study on fluoride containing groundwater, but MgSO_4 is the first use. In this paper, therefore, study a new method for removing fluorine from groundwater with MgSO_4, CaO powder regulate pH, studies the influencing factors of fluorine removal rate, such as pH, temperature and so on, obtain the proper treatment condition: 8% MgSO_4 solution 10ml, CaO powder regulate pH11, stir 5min at 40°C. Using this method, the concentration of fluorine ion in the groundwater is lower than the national provided drinking water criterion of <1.0mg/L, fluorine removal rate reach 93%.
