采用生物活性炭序批式反应器(BAC-SBR)处理ABS树脂生产废水,检测分析了废水在处理过程中的三维荧光、化学需氧量(COD)及总有机碳(TOC)的变化。对比研究了ABS树脂废水的荧光指纹特征和典型城市污水的差异,并重点研究了ABS废水在处理过程中总荧光强度去除率与COD和TOC去除率的相关性。结果表明,ABS废水的荧光指纹特征(Peak A/Peak B值)为0.124,远低于典型城市污水(1.6左右)。在废水处理过程中,废水总荧光强度去除率与COD和TOC去除率均呈很好的线性关系,其相关系数分别为0.98和0.99,即通过监测废水荧光强度的变化能够快速高效地分析废水中芳香类有机污染物的降解效率。
The wastewater from ABS resin production was treated with BAC-SBR, and the changes of three-dimensional fluorescence, chemical oxygen demand (COD) and total organic carbon (TOC) in wastewater were detected and analyzed. The differences between the fluorescent fingerprint characteristics and the typical urban sewage of ABS resin wastewater were comparatively studied. The correlation between the total fluorescence intensity removal rate and the removal rates of COD and TOC during the treatment of ABS wastewater was mainly studied. The results showed that the fluorescence fingerprint (ABS) of ABS wastewater was 0.124, much lower than the typical urban sewage (about 1.6). In the process of wastewater treatment, the removal rate of total fluorescence intensity and COD and TOC removal rate showed a good linear relationship, the correlation coefficients were 0.98 and 0.99, that is, by monitoring the changes in wastewater fluorescence intensity can quickly and efficiently analyze the wastewater Degradation efficiency of aromatic organic pollutants.
