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 investigate the degradation efficiency of polycyclic aromatic hydrocarbons (PAHs) in the simulated water produced by UV photodegradation, a preliminary study on the UV photolysis of polycyclic aromatic hydrocarbons (PAHs) in the produced water by homemade reactor was carried out. The results show that UV photodissociation of PAHs naphthalene and fluorene in the water produced by the oilfield has significant degradation ability. Laboratory tests show that the UVC (254 nm) UV irradiation at 254 nm for 60 min compared to UVA (365 nm) and UVB (308 nm) 99%. It can be seen that ultraviolet UVC has relatively stable and relatively high efficiency for the removal of naphthalene and fluorene in the produced water in terms of photolysis efficacy and exposure time.
