Disclosed is a method for recycling a lead oxide-containing waste. The method comprises the steps that (1) in the desulfurization reaction conditions, the lead oxide-containing waste is contacted with a desulfurizing agent, and the contacted mixture is subjected to solid-liquid separation to obtain filtrate and filter residue; (2) the filter residue is subjected to transformation reaction at a temperature of 350 to 370 DEG C, and the lead component in the filter residue is transformed into lead oxide; (3) the resulting product in the second step is contacted with alkali solution to allow PbO inside to be dissolved, and then subjected to solid-liquid separation to obtain PbO- alkaline solution; and (4) the PbO- alkaline solution in the third step is crystallized to obtain PbO crystals and alkali filtrate. The method can reduce energy consumption.
