摘　　要：对粉煤灰处理含氟废水进行了正交试验研究。结果表明各因素对F-去除率的影响顺序为:pH>V/M>T>CF-,极差R分别为49.6、9.1、4.9和3.6;在pH=5、V/M=10、T=3h时,粉煤灰对于CF-<500 mg/L的废水具有较好的去除效果;粉煤灰吸附F-的行为符合Langmuir等温方程,方程为Ce/qe=0.251 8Ce+6.087 3。The orthogonal experiment on removal of fluoride from wastewater by fly ash is reposted in this paper. The results show that the importance of each effect factors on fluoride removal rate is pH> V/M>T>C_f,R is 49.6,9.1,4.9,3.6 respectively;the optimal condition is pH=5,V/M=10,T=3h and Cf<500 mg/L;theaction of fluoride adsorption by fly ash fit the Langmuir isotherm formula perfectly and the formula is Ce/qe=0.251 8Ce+6.087 3.
