Abstract

Abstract:

By using single-crystalline TiO₂ nanowires as catalysts, photocatalytic degrading of benzene series in oil field produced water has been studied. It is found that the concentrations of benzene, toluene, paraxylene,metaxylene, orthoxylene can be degraded from 1 276.0, 432.3, 183.1, 1 319.4, 324.3 μg/L to lower than 70.6, 14.6,7.7, 24.5, 6.3 μg/L, respectively. The effluent water meets the requirements of the First Grade Standard of National Wastewater Comprehensive Discharge Standard, GB8978-1996.

Key words: single-crystalline titanium dioxide nanowires, photocatalysis, benzene, toluene, xylene

摘要：

以单晶纳米线TiO₂为催化剂，采用光催化氧化方法，对油田采出水进行处理，并对处理过程中苯系物的降解规律进行了研究。结果表明，经处理后废水中的苯、甲苯、对二甲苯、间二甲苯、邻二甲苯分别由1276.0、432.3、183.1、1319.4、324.3μg/L降至70.6、14.6、7.7、24.5、6.3μg/L，出水满足《国家污水综合排放标准》(GB8978-1996)一级标准。
