| 摘 要： | 采用臭氧氧化法处理硝基苯溶液,考察了反应时间、硝基苯浓度、溶液pH、臭氧流量等因素对硝基苯降解率的影响。研究结果表明：初始浓度200 mg/L时,pH 9.5、臭氧流量为300 mg/h,经30 min后硝基苯去除率达到95.3%以上。硝基苯降解反应符合一级反应动力学。TOC降解速率低于硝基苯分子降解速率,反应30 min后,TOC去除率比硝基苯去除率低45%左右,表明伴随着硝基苯的分解,由？OH或臭氧和硝基苯分子作用生成一系列中间产物。 |

| Abstract: | The wastewater containing nitrobenzene was treated by ozone,and the effect of initial concentration,pH value,oxidation time and the rate of ozone flow on degradation of nitrobenzene was discussed.Experimental results showed that the degradation process of nitrobenzene by ozone oxidation was in conformity with first-order dynamics model.When initial concentration was 200 mg/L,pH value was 9.5 and ozone flow rate was 300 mg/h,up to 95.3 % nitrobenzene was removed in 30 min.Meanwhile,the removal ratio of nitrobenzene was 45 % higher than that of TOC.Together with the analysis of ultraviolet spectroscopy,the results suggest that a series of intermediate products were produced by the oxidation of nitrobenzene with ozone or ·OH. |
