摘要
为了探讨紫外光光解人工模拟油田采出水中多环芳烃的降解效率,利用自制反应装置对油田采出水中多环芳烃(PAHs)的紫外光光解做了一个初步研究。研究结果证明,紫外光光解对油田采出水中的多环芳烃萘和芴有显著的降解能力。实验室的测试表明,与紫外UVA(365 nm)、UVB(308 nm)的光照相比,紫外UVC(254 nm)在光照60 min的条件下,2种多环芳烃各自的去除率都近似达到了99%。可见,在光解效力和暴露时间两方面,紫外UVC对采出水中萘和芴的去除具有相对稳定和比较高的效率。
In order to discuss degradation efficiency of ultraviolet photolysis on polycyclic aromatic hydrocarbons(PAHs) in artificial simulated oilfield produced water,a preliminary study was did for UV photolysis of polycyclic aromatic hydrocarbons(PAHs) in oilfield produced water by using a self-made reactor. Research results proved that ultraviolet photolysis had a significant degradation ability on naphthalene and fluorine of oilfield produced water. Compared to UVA(365 nm) and UVB(308 nm) irradiation,laboratory tests showed that the removal rate of naphthalene and fluorine both reached approximately 99% under the condition of UVC(254 nm)irradiation for 60 minutes. Therefore,UVC showed relative stable and higher efficiency in removing naphthalene and fluorine from the produced water in both aspects of photo-catalytic capacity and exposure duration.
