阳离子聚丙烯酰胺改性粉煤灰处理造纸废水的应用研究

The method of cationic polyacrylamide modified fly ash and their application in paper-making wastewater treatment

介绍了阳离子聚丙烯酰胺改性粉煤灰,并用制备的改性粉煤灰处理造纸废水。研究了改性粉煤灰的投加量、作用时间、溶液的pH、作用温度对废水SS、COD和色度去除率的影响。结果表明:在试验条件下,造纸废水的色度去除率可达94.9%,SS和COD去除率可分别达到95.6%和95.3%。

This paper briefly describes cationic polyacrylamide modified fly ash and how to use it in treating the paper-making wastewater. The effects of dosage of modified fly ash, time of reaction, wastewater, s pH and temperature on the removal rates of SS,COD and color are investigated by experiments. It shows that the discoloring rate can reach94.9 % and the removal rate of SS and COD can be 95.6 % and 95.3 % under optimal conditions.
