摘　　要：以粉煤灰为主要原料,碳酸钠为助溶剂,制备聚硅酸铝铁絮凝剂。对碳酸钠焙烧前后的粉煤灰进行了X射线衍射分析,并对铝铁浸出率进行了研究,对产品的最佳用量进行了确定。在最佳用量下,产品处理废水BOD、COD、色度、浊度的去除率分别能够达到76.47%、78.74%、82.79%、70.31%。The poly aluminum silicate iron flocculating agent was prepared with the fly ash as the main raw material, sodium carbonate as cosolvent. X-ray diffraction analysis was carded out with sodium carbonate and calcined before and after with the fly ash and aluminum, iron leaching rate was studied. The optimum dosage of the product was determined. Under the conditions of this preferred dosage, the BOD, COD, chroma, turbidity ofwastewater could reach 76.47%, 78.74%, 82.79%, 70.31%, respectively.
