  • 摘要: 酵母发酵废水经过厌氧膨胀颗粒污泥床（EGSB）-好氧膜生物反应器（MBR）组合工艺处理后，仍含有较高浓度的COD，不能满足排放要求。以发酵废水处理过程中MBR处理单元的出水为研究对象，选择活性炭催化臭氧氧化作为其深度处理工艺，以活性炭吸附和单独臭氧氧化工艺作为对比，重点考察了活性炭催化臭氧氧化深度处理工艺对发酵废水中有机物的去除效能，并借助红外光谱、三维荧光光谱和气相色谱-质谱联用等方法，详细分析了发酵废水深度处理过程中有机物的变化规律。研究结果表明，活性炭催化臭氧氧化深度处理工艺对发酵废水中的芳香族化合物、具有共轭双键的有机物及色度具有良好的去除效果；并且对废水中酸类、醇类和醛类等有机物有较好的降解、转化和去除效果。此外，活性炭催化臭氧氧化工艺还可以使以烷烃、卤代烃、醇类、酯类和酮类为主的大分子有机物的含量大幅度减少。
    Abstract: Even after being treated by ahybridprocess of anaerobic granular sludge bedand aerobic membrane bioreactor (EGSB-MBR), wastewater from yeast fermentation still cannot meet the requirements of the discharge standardsdue to its high COD value. In this work,activated carbon catalytic ozonation was employed and investigated as an advanced treatment method for the yeast fermentation wastewater effluent from the EGSB-MBR process, taking activated carbon adsorption and ozonation alone as comparative processes.Focusing on the removal efficiency of the organic compounds in fermentation wastewater during the activated carbon catalytic ozonation process, the variationsin the characteristics of organic compounds during the advanced treatment were systematically investigated using infrared spectrometry, three-dimensional fluorescence spectrometry, and GC-MS analysis. The results showed that not only the aromatic compounds and compounds with conjugated double bonds and colority, but also other organic compounds such as acids,alcohols, and aldehydeswere removed, degraded, or effectively converted by the activated carbon catalytic ozonation process. In addition,the activated carbon catalytic ozonation process could significantly reduce the contents ofmicromolecule organic mattersthat consist mainly of hydrocarbons, halogenated hydrocarbons, alcohols, esters, and ketones.
