The invention provides a nuclear power plant waste liquid treatment device performance verification method which comprises the steps: carrying out an orthogonal test design, preparing a feed liquid with a preset boron concentration, and filling the device with the feed liquid; starting a heat pump evaporation device, returning the distillate flowing out of the evaporation tower to the evaporation tower, and discharging and temporarily storing the distillate after the distillate formed by the secondary steam meets a preset discharge requirement; when the concentrated solution reaches a preset discharge requirement, discharging the concentrated solution for temporary storage, and mixing the discharged distillate with the concentrated solution for recycling; sampling the distillate and the concentrated solution at regular intervals and measuring the boron concentration; and then testing feed liquids with different concentrations, and synchronously carrying out comprehensive tests on the evaporation separation de
