| 摘 要： | 研究了UV/Fenton、日光/Fenton、UV/Tio2和UV/Fe2+等几种光氧化体系对模拟苯酚废水的氧化降解.结果表明,在上述几种光氧化体系中,UV/Fenton体系对苯酚的氧化降解能力最强,可很快地使苯酚矿化,日光/Fenton体系的降解能力次之;而UV/TiO2与UV/Fe2+体系对苯酚的降解效果较差.反应初始pH值与催化剂Fe2+用量等因素对苯酚的降解均有很大影响,光Fenton反应体系中,pH值在3～4范围内,苯酚的矿化效果较佳,pH值超过此范围,矿化率则急剧下降;苯酚的矿化率随着Fe2+用量的增加而逐渐增大,但当Fe2+达到一定量时,再增加Fe2+用量,苯酚的矿化率反而有所下降.

| Abstract: | The degradation of phenol in water by UV/Fenton, Sunlight/Fenton, UV/TiO2 and UV/Fe2+ processes were studied. The results showed that the effective degradation could be observed in UV/Fenton and Sunlight/Fenton reaction processes. The degradation of phenol by UV/TiO2 and UV/Fe2+ processes were not notable. The initial pH and the content of Fe2+ also have significant effect on the degradation of phenol. The degradation effects are optimum at pH 3 - 4 in UV/Fenton and Sunlight/Fenton processes. Effective degradation was observed as adding the right amount of Fe2+, however, high content of Fe2+ was unfavorable to phenol degradation by photo-Fenton processes. |
