摘要
利用盐交换改性和热改性粉煤灰,并利用改性的粉煤灰处理含磷工业废水。实验结果表明,盐交换改性后的粉煤灰除磷率高达99%,200℃热改粉煤灰可以便其除磷效率增加一倍。运用离子色谱法测定含磷溶液的磷酸盐浓度,测定方法快速准确。
Treatment of industrial phosphorus wastewater by using the modified fly ash with salt exchange and heat.The results showed that,modified fly ash treatment of phosphorus wastewater,the removal rate reached 99%,while double efficiency at 200 ℃.Detect the concentration of phosphate by ion chromatography,the method is fast and accurate.
