摘　　要：试验研究了粉煤灰、铁屑和锅炉烟气处理碱性印染废水及造纸废水的效果。试验结果表明 ,粉煤灰粒径越小 ,pH值越低 ,处理效果越好。当铁屑和粉煤灰组成为一腐蚀电池时 ,可缩短粉煤灰的混凝过程 ,锅炉烟气中的酸性物质和未燃尽的碳粒。The disposal efficiency of dyeing and paper making wastewater with fly ash, ferric scraps and flue gas is studied. The results show that the smaller the diameter of fly ash, the lower the pH of wastewater, and the higher the efficiency. The ferric scraps and fly ash which construct corrosive cell improve the flocculation of fly ash with wastewater. The acid matters and particulate materials in flue gas can also increase the efficiency of flocculation of fly ash with wastewater.
