Sediment spectral measurement device

The invention discloses a sediment spectral measurement device which comprises a light source, a spectrograph, an incident optical fiber, an emergent optical fiber, a base, a cuvette bracket, a cuvette, a host, a power supply, a lead and a data line. Wherein the light source is connected with the cuvette bracket through the incident optical fiber; the spectrograph is connected with the cuvette bracket through an emergent optical fiber; the host is connected with the spectrograph through a data line; the power supply is respectively connected with the light source, the spectrometer and the host through wires; the cuvette bracket is fixed on the base; and the cuvette is placed on the cuvette bracket. A measuring light path is changed into a vertical direction from a horizontal direction commonly adopted in a laboratory at present, so that the dynamic change of sediment concentration on the measuring light path caused by factors such as sedimentation of sediment in the measuring process is avoided, the measureme
