| Abstract: | This paper draws the diagram of the total fluoride ion in aqueous solution with calcium ion and pH.And combining with calcium chloride,PAC to remove fluoride from fluoride-containing wastewater,it has discussed the effect of calcium chloride and PAC.The results show that when the dosage of CaCl2 is 100 mg/L,the content of fluoride ion in wastewater can be reduced to 10.2 mg/L,when the pH value is 6-7,and the dosage of PAC is 400 mg/L,the fluoride ion concentration was 3.62 mg/L.It has simultaneously discussed the effect of PAC when 100 mg/L calcium chloride reaction 90min.The temperature has little effect on calcium fluoride to remove fluoride while the PAC has the most effective at 55 ℃. |
