An object of the present invention is to provide information on the type and concentration of organic substances remaining in treated water of factory waste water and to provide a more stable management method of factory waste water treatment than conventional methods. After drainage treatment of wastewater generated from a factory and containing dissolved organic matter, the fluorescence spectrum of the treated water is measured by changing the excitation wavelength continuously or intermittently between predetermined wavelengths, The excitation wavelength at the peak position of the fluorescence spectrum intensity of the treated water is obtained, the fluorescence wavelength at the excitation wavelength is obtained, and the type of the dissolved organic matter remaining in the treated water is estimated from the excitation wavelength and the fluorescence wavelength at the peak position. A method for managing factory wastewater treatment. [Selection] Figure 6 |
