改性粉煤灰处理含磷工业废水的研究

摘要

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.%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。
