通过采用负载FeSO4活性炭、CuSO4活性炭和一般活性炭作为微波催化剂处理抗生素废水的对比实验,研究不同负载方法对抗生素制药废水COD去除的差别,结果表明,负载FeSO4的活性炭作为催化剂的微波处理系统对COD的去除率最高.以微波诱导负载FeSO4的活性炭为催化剂对抗生素制药废水进行处理,结果表明,增大负载FeSO4活性炭质量,微波辐射时间和微波功率,均有利于抗生素废水中COD的去除,但各影响因素的取值并不是越大越好.对微波诱导负载FeSO4活性炭催化工艺处理抗生素废水进行反应动力学分析,结果显示,过程近似一级反应,其动力学方程为:lnC0/C=0.1413t+5.4121,r=0.9876.反应动力学常数为0.1413 min-1.
By using FeSO4 activated carbon, CuSO4 activated carbon and general activated carbon as the microwave catalyst for the treatment of antibiotic wastewater, the differences of COD removal of antibiotic pharmaceutical wastewater by different loading methods were studied. The results showed that the microwave treatment system with FeSO4 loaded with activated carbon The highest removal rate.With the microwave-induced activated carbon loaded with FeSO4 as the catalyst, the antibiotic wastewater was treated. The results showed that increasing the mass of FeSO4 loaded with activated carbon, microwave irradiation time and microwave power all contributed to the removal of COD from antibiotic wastewater, The results show that the process is similar to the first order reaction and the kinetic equation is: lnC0 / C = 0.1413t + 5.4121 , r = 0.9876. The reaction kinetic constant was 0.1413 min-1.
