摘要
探讨了利用粉煤灰、粉媒灰—生石灰体系处理含氟水的能力和影响因素。实验结果表明:应用粉煤灰可使含氟为20mg/L的原水降至10mg/L以下,使含氟50～100mg/L的原水的除氟率达50％以上;应用粉煤灰—生石灰体系处理含氟20～100mg/L的原水,均可使其降至10mg/L以下。用此法处理含氟废水工艺简单,操作方便,成本低廉,并可达到以废治废的目的。
In this study, we investigated experimentally the ability and affecting factors of fly ash in removing fluoride ions.The results were extended on possible technical application for the treatment of fluoride waste waters.Fluoride ions can be reduced from 20～100mg/L to below 10mg/L using fly ash—lime system.This method is more simple for operation and having lower operational cost, furthermore this wastewater can be treated by waste.
