摘要
本文介绍了聚酰胺-胺(4.0GPAMAM)树形分子改性沸石的制备,并用制备的改性沸石处理造纸废水。研究了改性沸石的投加量、作用时间、溶液的酸度、作用温度等对废水SS、CODCr和色度去除率的影响。研究表明在最佳的试验条件下,造纸废水的色度去除率可达95.1%,SS和CODCr去除率可分别达到93.5%和74.7%。
This paper briefly described how to modify the zeolite with 4.0G PAMAM to obtain PAMAM modified zeolite and how to use it in treating the paper-making wastewater. The effects of dosage of modified zeolite, time of reaction, wastewater＇s pH and temperature on the removal rates of SS,CODCr and color were investigated by experiments. It showed that the discoloring rate can reach 95.1 % and the removal rate of SS and CODCr could be 93.5 % and 74.7 % under optimal conditions.
