Abstract

Through static tests, this thesis studies the ability of activated alumina for absorbing the fluoride ion in fluorine-containing bitter salty water at Fuxin area, and fluoride ion in the regenerated liquid formed in a way that the original water sample is treated in a regeneration way with aluminum sulfate solution is removed with a coagulating precipitation method. Through comparison, this thesis analyzes the influence of different filter materials and coagulant varieties on the fluoride ion removal effect in fluorine-containing effluent, and also studies the influence of the concentration of regenerant aluminum sulfate solution and regeneration time on the regenerating effect of activated alumina. The study shows that as the filter material, the activated alumina has a good effect on removing the fluoride ion in the water sample, and the removal rate is 66.51%. On the same condition, as the coagulant, calcium chloride of the same mole quantity has the best effect on removing the fluoride ion, and the fluoride ion removal rate is 82.93%. On the conditions that the water temperature is 15 , the concentration of aluminum sulfate is 3%, the regeneration time is 3h and the regeneration velocity is 3m/k, the regeneration effect is the best, and the regeneration rate reaches 95.10%.
