The circuit device comprises a mounting shell, a driving unit, a photoelectric sensing unit, a deep ultraviolet LED lamp and a photoelectric conversion element, the mounting shell is provided with a containing cavity, and the deep ultraviolet LED lamp and the photoelectric conversion element are fixed to the two sides of the mounting shell respectively and arranged oppositely. The driving unit is used for driving the deep ultraviolet LED lamp to work and emitting deep ultraviolet rays, and the photoelectric sensing unit is used for receiving signals of the photoelectric conversion element and performing amplification filtering processing; the driving unit, the photoelectric sensing unit, the deep ultraviolet LED lamp and the photoelectric conversion element are all fixed on the mounting shell, so that the stability of the circuit device for detecting the COD through the ultraviolet spectrum can be effectively improved, and the phenomenon of poor contact caused by vibration is reduced. The arranged deep ultrav
