摘要
利用超声波辐射头孢克圬模拟废水,对比了单独超声空化效应以及向溶液中添加适量CCl4以强化超声空化效应两种条件下对溶液中头孢克圬的去除情况。实验结果表明,两种情况下溶液中头孢克圬的COD均有下降,可生化性得到明显提高,不过单独超声空化效应降解耗时较长,CCl4强化超声空化效应耗时短,降解效果较为明显。
Ultrasonic irradiation of cefixime simulated wastewater was carried out.The removal of cefixime in solution was compared under the conditions of ultrasonic cavitation alone and the addition of appropriate amount of CCl4 to the solution to enhance the ultrasonic cavitation effect.The experimental data showed that the COD of cefixime in the solution decreased in both cases,and the biodegradability was significantly improved.However,the ultrasonic cavitation effect alone took longer to degrade,and the CCl4 enhanced ultrasonic cavitation effect took less time and the degradation effect.More obvious.
