| 中文摘要 | 饮用水中的氟离子对人体具有重要意义。该文采用电絮凝-微滤组合工艺技术,去除饮用水中超量的氟离子,并探讨电流密度、极板间距、pH值对除氟效果的影响。实验表明:电絮凝-微滤组合技术除氟效果明显;水中氟离子浓度的对数值与反应时间呈线性关系。所研究的电絮凝反应器的最佳工作参数为:电流密度σ=15.8 A/m2,极板间距d=1.0 cm,pH值在5.7～7.0范围内。水中SO42-和PO43-离子的存在会影响除氟效率,而阳离子Fe3+、Mg2+、Ca2+在一定程度上促进除氟反应的进行。; The fluoride of drinking water is very important for human health.In this paper electrocoagulation-microfiltration(EC-MF) was used to purify groundwater contaminated by excessive fluoride.The tests analyzed the effects of current density,pH,and co-existing ions on the fluoride removal efficiency.The results demonstrate that the EC-MF process effectively removes the fluoride with the fluoride concentration decreasing to the linear relationship with the reaction time.The optimized defluoridation can be obtained in a pH range of 5.0—7.6,current density of 15.8 A/m2,and electrode distance of 1 cm.The co-existing anions of SO2-4 and PO34 show the negative influence on the fluoride removal,while Fe3+,Mg2+,and Ca2+ accelerate the removal.; 国家自然科学基金资助项目(50508018) |
