| 为研究改性甘蔗渣在处理印染废水脱色中的实际效果，以刚果红和亚甲基蓝模拟废水为研究对象，探讨了二甲基二烯丙基氯化铵（DMDAAC）-镁盐改性甘蔗渣在吸附剂不同投加量、pH值、反应时间、初始染料浓度、温度等实验条件下对刚果红和亚甲基蓝的吸附脱色效果。结果表明，DMDAAC-Mg2+改性甘蔗渣对溶液中刚果红和亚甲基蓝均具有良好的脱色作用。吸附剂投加量、pH、反应时间是影响改性甘蔗渣脱色性能的主要因素。正交实验结果显示，DMDAAC-Mg2+改性甘蔗渣对刚果红和亚甲基蓝脱色率分别达到97.96%和91.89%，在相同脱色条件下，与单因素改性甘蔗渣及原材料相比，DMDAAC-Mg2+改性甘蔗渣脱色效果最佳。 |
| 英文摘要: |
| In order to explore the decoloration efficiencies of modified bagasse for dyeing wastewater,aqueous solutions of Congo Red and Methylene Blue were taken as simulated wastewater to investigate the decoloration efficiencies by DMDAAC-Mg2+ modified bagasse under different conditions, such as the modified bagasse dosage, pH, contact time,initial concentration of dye and temperature. The results demonstrate that the DMDAAC-Mg2+ modified bagasse shows favorable decoloration efficiencies on both Congo Red and Methylene Blue.Themodified bagasse dosage, pH and contact time are the main factors which affect the decoloration efficiency. The orthogonal tests indicate that the maximum decoloration efficiencies can reach 97.96% and 91.89% for Congo Red and Methylene Blue, respectively. Under the same experiment condition, DMDAAC-Mg2+ modified bagasse exhibits the highest decoloration efficiency comparing with single factor modified bagasse and raw material. |
