污水中氟污染治理方法

The research on the ways of controlling fluorine in water

采用实验室规模的化学沉降法和混凝沉降法处理含氟水.研究结果表明:当联合投加CaCl2-AlCl3-Ce(SO4)2调节pH=7～8,搅拌反应30min时,能一次性将含F-500mg/L降至10mg/L以下.此种方法简单易行,便于操作.试验结果为含F-废水的达标处理提供了一定的科学依据.

The purpose of this paper is to remove fluorine in water by chemical deposition on a laboratory scale.Results show that the way of calcium chloride in combination with aluminium chloride and cerium in the water has a satisfactory effect.The concentration of fluoride ion in water can be reduced to 10mg/L at last. This method is simple and convenient.
