【摘要】 采用单极性三维电极法去除配制水中的氟离子,探讨了填充材料、极板间距和电压对除氟效果的影响。结果表明,填充颗粒比表面积越大、极板间距越小、电压越高,越有利于氟离子的去除。当采用活性炭颗粒作为填充材料、极板间距为10 mm、电压为5 V时,氟离子浓度可由4 mg/L降至0.8 mg/L,达到我国饮用水氟含量标准。更多还原

【Abstract】 The removal of fluoride using unipolar three-dimensional electrodes and the influencing factors were investigated.The result showed that the removal efficiency was improved with larger specific surface area of particle electrodes,decreased space between polar plates and higher voltage.When the space between polar plates was 10 mm and the voltage was 5 V,the fluoride concentration decreased from 4 mg/L to 0.8 mg/L using activated carbon as the particle electrodes,which reached the standard of drinking water of P.R.China.更多还原
