改性阳离子型絮凝剂在印染废水处理中的应用研究

Modified cationic flocculants in printing and dyeing wastewater treatment

以淀粉为原料合成了一种新型阳离子絮凝剂,通过实验研究了它对印染废水的处理效果,确定了适合印染废水处理的新型阳离子絮凝剂的最佳配比。实验表明:在NaOH/淀粉质量比1、醚化剂/淀粉质量比1.5,反应温度55℃、反应时间3h的条件下,新型絮凝剂对印染废水有良好的絮凝性能。

A new type of cationic flocculants was synthesized with starch. Through experimental study of its effect on printing and dyeing wastewater treatment, we identified the best ratio of this new type of cationic flocculants suitable for printing and dyeing wastewater treatment. Experiments show that NaOH / starch than the quality of etherificafion agem / starch mass ratio is1.5, the temperature is 55 ℃, under the conditions of reaction time of 3h, a new type of flocculant has good flocculation performance on printing and dyeing wastewater.
