The invention discloses a method for removing an ultra-fine glass fiber (AGM) partition plate from a waste lead paste in a lead-acid storage battery, belonging to the technical field of the lead-acid storage battery and solving the technical problems that the AGM partition plate and the waste lead paste are difficult to separate and the lead recovery rate is greatly reduced due to violent dismantling of a recovery broken device in a recovery stage of the storage battery in the prior art. The method comprises the following five steps of firstly, crushing, drying and weighing the lead-acid storage battery, and measuring the mass percent of the AGM partition plate contained in the waste lead paste; secondly, adding the waste lead paste into a reaction kettle, and adding a sodium hydroxide solution; thirdly, fully reacting under a condition of agitating, taking out a reaction material, carrying out filter pressing on the reaction material, and completing solid and liquid separation to obtain a filter cake and a filter liquid; fourthly, washing the filter cake with purified water, cleaning up an alkali liquid and a generated silicate in the filter cake, and drying the filter cake; and finally, washing the filter liquid with a doctor solution, precipitating the silicate, and recovering the alkali liquid for cyclic utilization.
