| 摘 要： | 利用工业氧化镁和硫酸制备一定浓度的硫酸镁,结合高岭土配制氧化镁烟气脱硫的模拟废水,通过分光光度计吸光度测定了聚丙烯酰胺、阳离子型聚丙烯酰胺和阴离子型聚丙烯酰胺在模拟废水中的絮凝效果.结果显示,3种絮凝剂中阳离子型聚丙稀酰胺的絮凝效果最佳,且在低使用浓度时显示出较好的絮凝效果.温度和pH对絮凝剂的絮凝效果也可产生较大的影响.

| Abstract: | The industrial magnesia and vitriol are used to produce magnesium sulfate in this paper,and the simulated wastewater is prepared using magnesium sulfate and kaolin.The flocculating effect of polyacrylamide,cationic polyacrylamide and anionic polyacrylamide is studied and compared through measurement of absorbency by spectrophotometer.The results show that the cationic polyacrylamide has the best flocculating effect among these three flocculants, and can be used at low concentration.The temperature and pH of the wastewater could change the flocculating effect of the flocculant evidently. |
