| 摘 要： | 在UV/H2O2和UV/Ti O2/H2O2两大氧化体系中,利用·OH的氧化原理,研究了不同影响因素(UV波长、p H、H2O2)对油田采出水中多环芳烃萘和芴降解效率的影响,找出处理萘和芴的最佳优化条件和组合。对萘和芴而言,UV/H2O2体系下双氧水的最佳条件分别为0.001,0.1 mol,UV/Ti O2/H2O2的优化组合是UVC,p H=8.5,O3=10g/L。实验结果表明:与UV/H2O2相比,UV/Ti O2/H2O2对油田采出水中的多环芳烃萘和芴的降解效果好。

PHOTOCATALYTIC OXIDATION OF NAPHTHALENE AND FLUORINE IN OILFIELD PRODUCED WATER AND FACTORS AND CONDITIONS OPTIMIZATION ANALYSIS OF THE HYDROXYL RADICAL OXIDATION DEGRADATION PROCESS |
| |
| Abstract: | The paper makes use of the principle of hydroxyl radical and studies degradation efficiency of polycyclic aromatic
hydrocarbons naphthalene and fluorene with the different factors ( UV wavelength，pH and H2O2
) under the UV/H2O2 and
UV/TiO2 /H2O2 oxidation systems． The results showed the best condition and combination． For naphthalene and fluorene，the
best condition of UV/H2O2 system was H2O2 = 0. 001 mol or 0. 1 mol． The best conditions of the UV/TiO2 /H2O2 system was
UVC，pH = 8. 5，ρ( H2O2
) = 10 g /L． The experimental results showed that the UV/TiO2 /H2O2 was better for the degradation
effect of naphthalene and fluorene in oilfield produced water than UV/H2O2 ． |
