The invention relates to a method for removing lead ions in lead and zinc beneficiation wastewater and belongs to the technical field of lead and zinc beneficiation wastewater treatment. The method comprises the following concrete steps: introducing lead and zinc beneficiation wastewater into a regulating tank, adding a sodium carbonate solution into the regulating tank, adding sulfuric acid ontoa water outlet pipeline of the regulating tank, regulating pH to be 9-10, enabling wastewater after adjustment by adding the sulfuric acid to enter a coagu-flocculation reaction tank, adding a coagulation flocculation agent into the coagu-flocculation reaction tank, enabling supernatant obtained through precipitation to enter a neutralizing tank, adding sulfuric acid into the neutralizing tank, regulating pH to be neutral, and further removing mercury. The method provided by the invention has the advantages that lead removal rate reaches more than 99%, lead ion content of the obtained recycledwater is reduced to be below 1 mg/m<3>, technological process is simple, wastewater treatment effect is stable, the used reagent is low in price, economical and practical, and industrial large-scaleapplication is facilitated.
