摘　　要：紫外光与氯氧化方法的发展是水处理技术中的一项重要进步。这种技术,被称为紫外光解氯(UV/氯),是一种新兴的高级氧化工艺(AOP)。它利用紫外光和氯气产生羟基自由基和活性氯,这些物质能够有效地降解水中的有机污染物。本论文中使用中压细管流紫外反应器来研究中压紫外结合氯对水中对氯苯甲酸的降解,并探讨不同因素对降解反应的影响。试验结果将与低压汞灯试验进行对比,从实验和理论的角度揭示中压汞灯效率较高的原因。The development of ultraviolet light and chlorine oxidation method was an important advance in water treatment technology.This technique,known as ultraviolet chlorolysis(UV/chlorine),is an emerging advanced oxidation process(AOP).It used ultraviolet light and chlorine gas to produce hydroxyl radicals and active chlorine,which can effectively degrade organic pollutants in water.In this paper,a medium pressure thin tube flow UV reactor was used to study the degradation of chlorobanzoic acid in water and to explore the influence of different factors on the degradation reaction.The test results will be compared with the low pressure mercury lamp test to reveal the reasons for the higher efficiency of the medium pressure mercury lamp from the experimental and theoretical perspective.
