采用介质阻挡放电来直接处理制药废水,设计了管式介质阻挡放电反应装置,研究了废液流量、放电电压、反应时间对甲胺、COD和BOD5去除率的影响,初步分析了主要有害物质降解过程。结果表明,该方法对甲胺、COD和BOD5的去除率均有较好的作用,提高了制药废水的可生化性,可作为该废水处理的生化预处理技术。 Dielectric barrier discharge was used to treat pharmaceutical wastewater directly. A tubular dielectric barrier discharge reactor was designed. The effects of waste flow rate, discharge voltage and reaction time on the removal rates of methylamine, COD and BOD5 were studied. The degradation of major pollutants process. The results show that this method has a good effect on the removal rate of methylamine, COD and BOD5, improves the biodegradability of pharmaceutical wastewater, and can be used as biochemical pretreatment technology of the wastewater treatment.
