摘　　要：利用紫外、红外拉曼光谱和GC/MS对传统皂素生产工艺、S-F工艺和E-S工艺头道液废水的有机物组成进行了分析。结果表明,传统工艺、S-F和E-S工艺头道液废水的有机物主要是醛类,此外,传统工艺头道液中检测到的22种有机物中,还有大量生物难降解的杂环类(12.24%);而S-F和E-S工艺头道液中检测到的25种和31种有机物主要是较易生物降解的醇类、烷烯烃、有机酸和酯类,杂环类分别降至7.83%和4.80%。本项研究有助于E-S和S-F皂素生产清洁工艺的推广应用。The organic compositions of wastewater in the first stage during the traditional,the S-F,and the E-S processing for treating Dioscorea zingiberensis C.H.Wright were analyzed using UV,infrared raman spectroscopy,and GC/MS technologies.The results showed that aldehyde was the first compound in all three wastewaters.Totally,22,25,and 31 organic components were detected in the wastewaters of the traditional,the S-F,and the E-S processing,respectively.Recalcitrant heterocycle compounds with a proportion of 12.24% were also detected in the traditional processing.On the contrary,biodegradated components including organic acids,alcohols,esters,and olefin/paraffin were found mainly in the S-F and E-S processing.Heterocycle ratio decreased to only 7.83% and 4.80% for the S-F and E-S processing,respectively.Our results provide useful information for application of the S-F and the E-S processing on Dioscorea zingiberensis C.H.Wright diosgen.
