摘  要:
[目的]研究UV光催化联合ClO2降解水溶液中苯酚的方法。[方法]以模拟苯酚废水为处理对象,ClO2为氧化剂,UV作为辅助手段,考察ClO2/UV氧化处理苯酚废水工艺中ClO2投加量、UV辐照时间、废水pH等因素对苯酚处理效果的影响。[结果]处理质量浓度为100 mg/L的苯酚废水,pH在8左右,ClO2投加量为140 mg/L,UV辐照时间为30 min的条件下,处理效果最好,苯酚去除率高达99.6%。并且在相同的处理条件下,ClO2/UV氧化苯酚的效率明显高于单一ClO2或UV法,同时大大缩短了反应时间。[结论]ClO2/UV氧化法是一种行之有效的含酚废水的处理方法。

摘  要:
[Objective] The method of the phenol in wastewater was decomposed with the UV photocatalytic method combined with chlorine dioxide(ClO2) treatment was studied.[Method] The effect of the adding amount of ClO2 as oxidant,the irradiation time of UV as assistance,the pH of the wastewater and other factors on the decomposition of phenol was experimented.[Result] The degradation rate of phenol in wastewater could reach up to 99.5% while the pH was 8,the adding amount of ClO2 was 140 mg/L and the irradiation time of UV was 30 minutes.Under the same condition,the combination of ClO2 and UV was much better and faster than that of single use of ClO2 or UV.[Conclusion] The method of ClO2/UV oxidization in treatment of the wastewater containing phenol was effective.
