PAMAM改性沸石及其在油墨废水处理中的应用研究

Preparation of PAMAM-modified Zeolite and Application in Wastewater Treatment of Printing Ink

本文介绍了聚酰胺-胺(4.0G PAMAM)树形分子改性沸石的制备,并用制备的改性沸石处理实际油墨废水。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CODCr和色度去除率的影响。研究表明,在最佳的试验条件下,油墨废水的CODCr和色度去除率分别达到93.7%和98.1%。

This paper briefly describes how to mix the zeolite with 4.0G PAMAM to obtain PAMAM modified zeolite and how to use it in treating the printing ink wastewater.The effects of dosage of modified zeolite,time of reaction,pH of wastewater and temperature on the removal rates of CODCr and color are investigated by experiments.It shows that the removal rate of CODCr and chroma can be 93.7% and 98.1 % under optimal conditions.
