Abstract:
Antibiotics are refractory substances,and impossible to be removed by ordinary physicochemical methods. Dielectric barrier discharge plasma(DBD) has been used for the degradation of erythromycin(ETM),and the influ-ences of ETM initial mass concentration,discharge power,liquid flow rate,and air flow on the degradation rate,and the TOC change in the degradation process have been investigated. The results show that when the discharge power is 80 W,initial pH 8,the liquid flow rate 50 L/h,and gas flow rate 60 L/h,after 0.5 mg/L of the ETM solution has been treated for 60 min,the COD removing rate is 63.99%. After 60 min,the change trend of TOC tends to stable.

摘要： 抗生素属于难降解物质，普通的物理化学方法不能有效去除。利用介质阻挡放电等离子体（DBD）降解红霉素（ETM），考察ETM初始质量浓度、放电功率、液体流速、空气流量对降解率的影响以及降解过程中TOC的变化。结果表明：放电功率为80 W、初始pH为8、液体流速为50 L/h，空气流量为60 L/h时，处理0.5 mg/L ETM溶液60 min后COD去除率为63.99%，60 min后TOC变化趋于平稳。
