摘要

采用三维荧光技术研究ABS(Acrylonitrile-butadiene-styrene)树脂生产废水的荧光指纹特征及其在三相三维电极反应器的处理过程中的变化规律

研究了极板间电压对废水中芳香类污染物分解转化的影响。研究结果表明

ABS废水的荧光中心在激发波长和发射波长分别为225 nm和340 nm处

其荧光强度最强

为主峰(Peak A);激发波长和发射波长分别为275 nm和340 nm处的荧光次强

为次强峰(Peak B)。荧光指纹特征(

PeakA

PeakB

)为8.1。当极板间电压较高时

废水的化学需氧量(Chemical Oxygen Demand

COD)去除率和总荧光强度去除率均较高

能够高效地分解转化废水中的芳香类污染物。在不同的极板间电压下

废水的总荧光强度去除率与COD去除率均呈很好的线性关系

且相关系数均高达0.96以上

即通过监测废水荧光强度的变化就能够快速高效地检测分析废水中芳香类有机污染物的分解转化效率。

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

=225/340 nm (Peak A) and

=275/340 nm (Peak B)

respectively

and the ratio of

PeakA

PeakB

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.
