CPAM改性沸石应用于造纸废水的处理

CPAM modified zeolite and its applying experiment in paper-making wastewater treatment

介绍了阳离子聚丙烯酰胺改性沸石,并用制备的改性沸石处理制浆造纸废水。研究了改性沸石的投加量、作用时间、溶液p H、作用温度对废水SS、CODCr和色度去除率的影响。结果表明:在试验条件下,制浆造纸废水的色度去除率可达96.6%,SS和CODCr去除率可分别达到97.1%和94.7%。

This paper brief ly describes CPAM modifying zeolite and how to use it in treating papermaking wastewater. The effects of dosage of modified zeolite, time of reaction, wastewater＇s p H and temperature on the removal rates of SS, CODCr a nd color we re i nve st igat e d by experiments. The result shows that the discoloring rate can reach 96.6% and the removal rate of SS and CODCr can be 97.1% and 94.7% respectively under the optimal conditions.
