The invention discloses an electrolytic cell for an electrochemical test of medicament dreg treatment and a use method thereof. The electrolytic cell comprises a bottom plate, a water tank, an electrolytic tank, and a filter tank, wherein the bottom of the water tank is fixed at the left of the top of the bottom plate, two sides of the bottom of the electrolytic tank are fixed at two sides of thetop of the bottom plate through support columns, and the bottom of the filter tank is fixed at the right of the top of the bottom plate. The invention relates to the technical field of medicament dregelectrochemical test devices. Through adoption of the electrolytic cell for the electrochemical test of medicament dreg treatment and the use method thereof, use states of a first quantitative frameand a second quantitative frame are controlled, medicament dregs in the first quantitative frame flow into the electrolytic tank, or medicament dregs in both the first quantitative frame and the second quantitative frame flow into the electrolytic tank, the quantity of medicament dregs entering the electrolytic tank is controlled, electrolytic detection is performed for two times, then detection results are compared when medicament dreg electrolytic detection quantities of two times are learnt, therefore, the electrolytic cell is improved in detection accuracy, is simple to operate, and can bewidely promoted and used.
