摘要
利用高压电晕-臭氧的协同作用来处理废水是一项新技术。高压电晕和臭氧均能在水溶液中产生·OH。·OH能无选择地氧化有机污染物如苯乙酮、石炭酸、对氯苯酚等,处理效率高、无二次污染。高压电晕产生的紫外线和高能电子能促进臭氧产生·O和·OH,臭氧气泡的局部放电使电晕产生更多的·OH,二者联用具有很好的协同性。因此该技术在难降解有机废水的处理方面具有较大的优越性。
<abstract>gh voltage corona - ozone technology is a new process for wastewater treatment. Corona and ozone can produce·OH, which can oxidize without choice different organic pollutants, such as acetophenone, phynolic acid, p - chlorophenol and so on. Ultraviolet light and high - energy electron produced by high voltage corona can accelerate the production of·O and·OH from ozone, partial electric discharge from ozone bubble can make corona produce more quantity of·OH. The combination of the two has a good cooperative effect. The process has many advantages in treatment of wastewater containing nonbiodagradable organics, such as high efficiency and without secondary pollution.
