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pH、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 briefly describes CPAM modifying zeolite and how to use it in treating papermaking wastewater. The effects of dosage of modiifed zeolite, time of reaction , wastewater's pH and temperature on the removal rates of SS, CODCr and color were investigated 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.
