Abstract Fluorescence spectroscopy is widely used to elucidate the origin and structure of organic matters in water substance. Due to its high sensitivity,good selectivity and nondestructive nature,fluorescence technique is suitable to the study of chemical and physical properties of organic matters. Three-dimensional excitation emission matrix fluorescence spectroscopy (3DEEM) was applied to analyze the effects of organic removal by traditional purification process. The results show that 3DEEM is able to disclosure the changes of organic matters in the treatment processes effectively. Traditional purification process can remove some fulvic-like organic matter,but cannot remove it completely. Coagulant sedimentation basically does not have an effect of fulvic-like organic matter removal. The removal proportion of fulvic-like organic matter through filtration is 5%-15%.
