采用自制的弱碱性阴离子交换纤维处理含活性染料的印染废水,研究了该方法的处理效果及其影响因素。结果表明:弱碱性阴离子交换纤维处理含活性染料的印染废水有良好的效果,接枝率为70%~80%的离子交换纤维处理效果最佳。离子交换纤维用量、pH、反应温度和反应时间对处理效果有重要影响。初步探讨了离子交换纤维的脱色机理。
Anion exchange fiber containing alkalescence made by ourselves was used to treat printing and dyeing wastewater containing reactive dye, pollutants removal efficiency and effect factors of the method are investigated. Results show that anion exchange fiber containing alkalescence has a great effect on printing and dyeing wastewater containing reactive dye treatment, and the pollutants removal efficiency is the best when grafting rate of ion exchange fiber is 70%~80%. These factors such as amount of ion exch...
