| Abstract: | Papermaking wastewater is a kind of wastewater with high content of organic matters,high colority and it is hard to be degraded.The methods of modifying attapulgtie and treating papermaking wastewater are studied.The results show that the modified attapulite used in removes COD and color from papermaking wastewater by 83.4% and 95.6% respectively.This research provides valuable experimental data for modifying natural absorbents and applying them to treating papermaking wastewater. |
