摘要: 针对栽桑养蚕过程中废弃桑枝的综合利用，以废弃桑枝和十六烷基三甲基溴化铵为原料，经微波辐射加热制备高分子絮凝剂。通过单因素实验确定了制备絮凝剂的最佳工艺条件，并采用该絮凝剂处理造纸废水。结果表明，制备絮凝剂的最佳工艺条件为：NaOH溶液浓度为8%，碱化温度为室温，碱化时间为30 min，Fe2+/H2O2的加入量为14 mmol/L，桑枝粉与十六烷基三甲基溴化铵的质量比为1∶1，微波功率为500 W，反应温度为90℃，反应时间为60 min。制备的絮凝剂对造纸废水具有高效絮凝性能，在造纸废水pH值为10，絮凝剂投加量为100 mg/L的条件下，COD和浊度去除率分别达48.2%和81.4%。该絮凝剂对造纸废水的絮凝效果明显优于氯化铝，与聚合氯化铝相当，但其用量明显低于氯化铝和聚合氯化铝。

Abstract: Waste mulberry branch and hexadecyl trimethyl ammonium bromide (CTAB) were used to prepare a novel flocculant (GXSZ) by microwave irradiation. The optimal conditions of preparation of the flocculant were determined. The flocculant was used to treat pulp wastewater. The result shows that the optimal conditions of preparation of flocculant are as follows: the concentration of sodium hydrate is 8%, alkalization temperature is room temperature, alkalization time is 30 min, dosage of initiator Fe2+/H2O2 is 14 mmol/L, the mass ratio of mulberry branch to CTAB is 1∶1, the microwave power is 500 W, reaction temperature is 90℃ and reaction time is 60 min. The flocculant prepared under optimal technology conditions has distinct flocculation efficiency for pulp wastewater. When the pH value of pulp wastewater is 10, the dosage of the flocculant GXSZ is 100 mg/L, the removal rate of COD and turbidity reaches to 48.2% and 81.4%, respectively. As for treating pulp wastewater, the performance of the flocculant GXSZ is superior to the aluminum chloride，and is comparative to polymerized aluminum chloride, but the dosage of the flocculant GXSZ is significantly lower than that of aluminum chloride and polymerized aluminum chloride.
