研究了电凝聚法对模拟高含氟地热水（氟含量8mg／L，pH8，水温60℃，矿化度200mg／L）的除氟。结果表明，电凝聚法对地热水的除氟可控并能获得理想除氟效果（处理水氟含量<1mg/L）。最佳工艺条件为：进水pH值5.5～6.0，电解电流密度约15A／m2，电解槽停留时间4～5min，倒极时间5～10min。 The electro-coagulation method was used to simulate the removal of fluoride from high-fluorine geothermal water (fluorine content 8mg/L, pH8, water temperature 60°C, and salinity 200mg/L). The results show that the electrocoagulation method can control the defluorination of geothermal water and obtain the ideal fluoride removal effect (treatment water fluorine content <1mg/L). The optimum process conditions are: influent pH value of 5.5-6.0, electrolytic current density of about 15 A/m2, electrolysis cell residence time of 4-5 min, and reversal time of 5-10 min.
