石油类行业含油污水同步光谱特性解析

污水中所含矿物油成分具有荧光特性。利用荧光分析法实验研究了大庆采油厂13#口、大庆化工、中石化炼油厂的进口、出口含油污水样本的同步荧光光谱。实验结果表明,选择波长差△λ=40nm、60 nm和80 nm,能够将大庆采油厂、大庆化工和中石化炼油厂的进出口含油污水区分开。随着△λ的变化,相同浓度的油溶液同步光谱,不仅光谱形状、数目和峰位发生了变化;同行业含油污水进出口的同步荧光光谱差别也较大。

Synchronous Spectral Characteristic Analysis of Oil Industry Sewage

The oil contained in wastewater has fluorescence characteristics. The fluorescence characteristics of import and export oily wastewater samples from Daqing Oil Production Plant 13 #, Daqing Chemical Plant and Petrochemical Refineries were investigated by the fluorescence analysis. Synchronous fluorescence spectroscopies of oily wastewater were obtained. The results show that, by selecting the wavelength difference Δλ=40 nm, 60 nm and 80 nm, refinery oily sewage of the oil production plant in Daqing, Daqing Chemical and Petrochemical from import and export can be distinguished from each other. When Δλ changes in the synchronous spectrum of the same concentration of the oil solution, the spectral shape, number and peak position change. Synchronous fluorescence spectrum of wastewater from the import and export of the same industry have large differences.
