摘要: 采用厌氧折流板反应器(ABR)处理柠檬黄模拟废水,研究在不同水力停留时间(HRT)下,ABR对柠檬黄及COD的去除效果,实验结果表明,HRT为30 h时,柠檬黄经ABR厌氧处理后的去除率达96.4%,COD去除率达97.9%.同时利用红外光谱、UV-Vis、离子色谱分析柠檬黄的降解产物.从红外光谱和UV-Vis分析得出,柠檬黄经ABR厌氧处理后偶氮键断裂,生成的芳香胺类化合物被进一步降解为含苯环、含萘环的化合物;离子色谱定性分析得出柠檬黄分子中的磺酸基转化成了硫酸根.

Abstract: In this research, an anaerobic baffled reactor (ABR) was used to treat simulated wastewater containing tartrazine, and the effect of hydraulic retention time (HRT) on the removal of tartrazine and COD was also studied. Results showed that the removal rate of tartrazine and COD reached 96.4% and 97.9% respectively after anaerobic treatment by ABR with HRT of 30 h. Meanwhile, infrared spectroscopy, UV-Vis spectra and ion chromatography was used to analyze the degradation products of tartrazine. From the results of infrafed spectroscopy and UV-Vis spectra, the azo bond of tartrazine was found broken after anaerobic treatment by ABR, and reduced to aromatic amines which can be further degraded to compounds containing benzene ring or naphthalene ring. In addition, the analysis of ion chromatography showed that the sulfonic acid group in tartrazine molecular could be transformed into SO42-.
