摘　　要：利用红外、凝胶色谱、气-质联用等技术研究皂素废水在强对流微电解-芬顿氧化耦合技术下有机物的变化,揭示皂素废水降解的化学本质。研究发现,强对流微电解-芬顿氧化耦合技术能显著降低皂素废水的COD值、色度、氨氮和硫酸根离子浓度,提高废水的可生化性。降解反应主要发生在不饱和化合物的不饱和键上,苯及其衍生物是一类难降解的有机物。Introducing the change of organics of Saponin wastewater under the coupling technology of strong convection micro-electrolysis and Fenton oxidation by means of IR,GPC and GC-MS.The results show that the coupling technology of strong convection micro-electrolysis and Fenton oxidation can significantly reduce the COD,colorfulness,ammonia nitrogen and[SO4^2-]in diosgenin wastewater,and improve the biodegradability of the wastewater.It was found that the degradation reaction mainly occurred on the unsaturated bond of unsaturated compounds.Benzene and its derivatives are a class of refractory organic compounds.
