三相三维电极反应器中芳香类污染物荧光光谱特征的变化规律
The Variation Trend of Fluorescence Characteristics of Aromatic Organic Pollutants in The Three-phase Three-dimensional Electrode Reactor
摘要
Abstract
Excitation-emission matrix (EEM) technology was used to study fluorescence properties of acrylonitrile-butadiene-styrene (ABS) resin wastewater with its variation trend in the treatment process. The effect of different voltage for the degradation of aromatic compounds was studied significantly. The results show that two fluorescence center of ABS resin wastewater load at the wavelength of λex/λem = 225/340 nm ( Peak A) and λ ex/λ em = 275/340 nm ( Peak B), respectively, and the ratio of IpeakA/IpeaB is 8.1. A higher chemical oxygen demand (COD) and total fluorescence intensity removal efficiencies under a higher voltage, and the aromatic compounds of ABS wastewater can be decomposed efficiently. Under the different voltage, there is a good linear correlation for COD and total fluorescence intensity removal efficiencies. And their correlation coefficients are all over than 0. 96, therefore the decomposition efficiency of aromatic compounds for ABS wastewater can be determined and analyzed efficiently using EEM technology.关键词
