PPROBLEM TO BE SOLVED: To provide a method for analyzing a suspended substance, calculating a concentration for each particle diameter in a liquid as a sample and a sum of the concentrations of each of the particle diameters (concentration) from a value of a measured ultrasonic attenuation rate without the usage of the optically measured turbidity. PSOLUTION: The ultrasonic attenuation rate α(fSBj/SB) is calculated from a water temperature and measured data of a frequency spectrum (a plural sets of the frequencies and the measured values of the spectrums), a concentration cSBi/SBfor each particle diameter is calculated from a partial regression coefficient βSBij/SBand the ultrasonic attenuation rate α(fSBj/SB), a concentration C of the sample liquid is calculated from the concentration cSBi/SBfor each particle diameter, a unit concentration attenuation rate λ(fSBj/SB) is calculated from the concentration C and the ultrasonic attenuation rate α(fSBj/SB), and a relative particle amount is calculated from the partial regression coefficient βSBij/SBand the unit concentration attenuation rate λ(fSBj/SB). Even in the liquid with very low clarity, the sum of the concentration for each of the particle diameter (concentration), the relative particle amount, and capacity (volume) concentration, in consideration of the peculiar attenuation rate based on a particle size and the particle diameter of the suspended substance, are measured.

解决方案:超声波衰减率α(f j SB>)是根据水温和频谱的测量数据(多组频率和频谱的测量值)计算得出的,根据偏回归系数β ij SB>和超声衰减率α(f j SB>来计算每个粒径的浓度c i SB> ),根据每种粒径的浓度c i SB>计算样品液体的浓度C,并根据浓度计算出单位浓度衰减率λ(f j SB>)浓度C和超声衰减率α(f j SB>),并根据偏回归系数β ij SB>和单位浓度衰减率λ计算相对颗粒量;(f j SB>)。即使在澄清度很低的液体中,考虑到基于粒径和粒径的特殊衰减率,每种粒径的浓度(浓度),相对粒径和容量(体积)浓度的总和也是如此。测量悬浮物的粒径。
