摘　　要：采用三维荧光光谱(3DEEM)技术考察了农家乐污水中溶解性有机质的三维荧光特性。结果表明,农家乐污水中的有机污染物荧光峰以类蛋白质荧光峰为主,其中高激发波长类色氨酸荧光峰Peak T最强,其次是低激发波长类色氨酸荧光峰Peak S和低激发波长类酪氨酸荧光峰Peak D;综合性农家乐污水的Peak S和Peak D荧光强度比以餐饮为主的农家乐污水的要强。农家乐污水经受纳水体稀释和净化后,类蛋白质荧光强度仍远高于地表水的,其对受纳水体的污染不容忽视。Three-dimensional fluorescence spectrum was applied to characterize the three-dimensional fluorescence properties of dissolved organic matter （DOM） in wastewater from farmer household tourism. The results show that DOM fluorescence properties are characterized by protein-like peaks, and high-excitation wavelength tryptophan-like peak T is strongest among all protein-like fluorescence peaks, while low-excitation wavelength tryptophan-like peak S and low-excitation wavelength tyrosine-like peak D are weaker. The fluorescence intensities of peak S and peak D of comprehensive wastewater from farmer household tourism are stronger than those of restaurant wastewater from farmer household tourism. The fluorescence intensity of protein-like in the wastewater from farmer household tourism is still higher than that of surface water, though the wastewater is diluted and purified by the receiving water body. The pollution of receiving water body by the wastewater from farmer household tourism should not be ignored.
