摘　　要：采用介质阻挡放电等离子体技术,以COD为评价指标,对十二烷基吗啉模拟废水进行降解。考察了废水初始质量浓度、p H、催化剂、曝气量、放电功率以及放电时间对降解效果的影响。结果表明,十二烷基吗啉废水最佳降解条件:废水初始质量浓度为20 mg/L,p H为5,曝气量为200 m L/min,放电功率为260 W,放电时间为4 h。在此条件下,十二烷基吗啉降解率达到85%。The simulated dodecylmorpholine （DMP） wastewater has been degraded by dielectric barrier discharge （DBD） plasma technology,using COD as evaluation index. The effects of initial mass concentration, pH, catalyst, aeration rate, discharge power and discharge time on degradation effectiveness are investigated. The results show that the best degradation conditions of DMP are as follows ： initial mass concentration is 20 mg/L, pH=5, aeration rate 200 mL/min, discharge power 260 W and discharge time 4 h. Under the best degradation conditions, the degradation rate of DMP could reach 85%.
