【摘要】：采用三維熒光光譜(EEM)和熒光區(qū)域指數(shù)分析法研究了垃圾滲濾液的熒光光譜特性。滲濾液經(jīng)不同超聲頻率處理后,位于λ_(Ex)/λ_(Em)=270/345 nm和240/449 nm的特征峰消失,位于λ_(Ex)/λ_(Em)=330/430 nm(峰a)和280/391 nm(峰b)的特征峰在80 k Hz時(shí)峰強(qiáng)增加幅度和位移變化最大,但兩峰強(qiáng)度之比r(a,b)和EEM的P_(Ⅲ,n)與P_(Ⅴ,n)增加幅度最低;不同初始p H滲濾液經(jīng)超聲處理后,特征峰位移出現(xiàn)明顯差別,除p H為11時(shí)P_(Ⅲ,n)有所下降外,其余P_(Ⅴ,n)和P_(Ⅲ,n)都呈上升趨勢(shì),pH為3時(shí)P_(Ⅴ,n)增加幅度最顯著;提高滲濾液初始濃度后,發(fā)現(xiàn)P_(Ⅲ,n)和P_(Ⅴ,n)升幅增大,P_(i,n)的變化規(guī)律顯示對(duì)超聲的敏感程度是色氨酸類有機(jī)物酪氨酸類有機(jī)物微生物瀝出物富里酸類有機(jī)物腐殖酸類有機(jī)物;GC/MS分析結(jié)果表明超聲處理后滲濾液中芳烴和烷烴有機(jī)物相對(duì)含量減少,醇類、羧酸和酯類有機(jī)物相對(duì)含量增加。
[Abstract]:The fluorescence spectrum characteristics of landfill leachate were studied by three dimensional fluorescence spectroscopy (EEM) and fluorescence region index analysis. The characteristic peaks of the leachate in the Ex / lambda (Em) =270/345 nm and 240/449 nm were disappearing after the treatment of different ultrasonic frequencies, and the peak intensity of the characteristic peaks of the lambda Ex / Ex / [Em) = 330/430 nm (peak a) and the peak (peak) The increase of amplitude and displacement is the greatest, but the increase of the two peak intensity ratio R (a, b) and EEM P_ (III, n) and P_ (V, n) is the lowest, and the characteristic peak displacements of different initial P H leachate are obviously different. Except for P H is 11, the rest (III) and (III)) all increase. When the initial concentration of leachate was increased, the increase of P_ (III, n) and P_ (V, n) was found, and the variation of P_ (I, n) showed that the sensitivity to ultrasound was the organic compounds of tryptophan organic compounds, organic compounds, organic compounds, fulvic acids, organic compounds, and organic compounds. The results of GC/MS analysis showed that the aromatics in the leachate after ultrasonic treatment The relative content of organic compounds and alkanes decreased, and the relative content of alcohols, carboxylic acids and esters increased.
