饮用水胶泥除氟研究

A study on reducing fluorine with clay in drinking water

通过实验和应用观察表明胶泥确实具有除氟作用,除氟后水质各项成份符合国家规定饮水卫生标准。胶泥除氟机理是由于伊利石(Al_2O_3)胶体对氟离子的吸附作用,除氟方法采用过滤井形式,该方法除氟经济、实用、可靠,适合沧州农村使用。

This paper described the results of observation on elimination of excess fluo-ride with clay in drinking water.Treated water is uncolour and tasteless and allindex of water quality correspond to national criteria.The mechanism of defluoridation with clay based on the adsorption to fluori-ne by illite (Al_2O_3) in clay.This method is low-priced,practical and dependable.It is useful in Cang Zhou district countryside.
