DEGRADATION OF PHENOL BY HYDROXYL RADICAL PRODUCED BY DISCHARGE

摘要：

The phenol wastewater of high concentration was treated by hydroxyl radical produced by micro-gap dielectric barrier discharge plasma in this article.The phenol elimination efficiency increases with increasing supply hydroxyl radical concentration.The higher the initial concentration of wastewater iS，the slower is the elimination efficiency of phenol and the greater is the treatment quantity of phenol.Especially，the phenol elimination efficiency of wastewater whose initial concentration is 1000mg·L-1 can reach 99.83％，and the finally concentration of treated wastewater is 2.14mg·L-1.The relation between pH value change and hydroxyl radical concentration was stated and explained.The change of ultraviolet scan spectra at different stage declared that the degradation effect is apparent.
