改性香樟叶快速降解β-内酰胺类抗生素废水

Study on the Rapid Degradation of Beta Lactam Antibiotic Wastewater Using Modified Camphor Leaves

以香樟叶为原材料,微波条件下利用尿素进行改性,研究改性香樟叶对β-内酰胺类抗生素废水处理效果的影响.通过与普通香樟叶颗粒处理效果相比较,改性香樟叶颗粒处理该类废水效果显著,在投加量0.500 0g,温度80℃,反应时间50min,废水初始浓度0.480 0g/L时,处理效果最佳.在此条件下,抗生素废水的去除率可达72%,具有一定的应用价值.

Using camphor leaves as the raw material modified with urea under microwave conditions,the effect of modified camphor leaves on the treatment of antibiotic wastewater is studied.Compared with the treatment effect of common camphor leaf granules,the modified camphor leaf granules have a significantly better effect on the treatment of such wastewater.The best results are obtained with dosage 0.500 0 g,temperature 80℃,reaction time 50 min,and initial concentration of wastewater 0.480 0 g/L.Under these conditions,the removal rate of antibiotic wastewater can reach 72%,indicating certain practical values.
