NOVELTY - Recovery of tribasic lead sulfate from a waste lead acid storage battery comprises recycling anode electrode grid board in a nitric acid (HNO3) solution; overcasting cathode electrode and grid plate with lead sulfate (PbSO4), placing residue in ammonium bicarbonate (NH4HCO3) solution, filtering, and placing residue in HNO3 solution; electrode melting by heating to 350-400 degrees C, and casting to an ingot; adding 20-98% sulfuric acid (H2SO4) solution to lead nitrate (PbNO3)2 solution, and filtering; and adding aqueous ammonia at 40-80 degrees C, reacting for 30-60 minutes, and filtering.    USE - Method for the recovery of tribasic lead sulfate from a waste lead acid storage battery (claimed).    ADVANTAGE - The method is simple and inexpensive. The waste lead acid storage battery is recovered by the use ratio of 100%, such that the waste lead acid storage battery is recycled at the largest proportion.    DETAILED DESCRIPTION - Recovery of tribasic lead sulfate from a waste lead acid storage battery comprises:    (A) waste battery disassembling by disassembling plastic shell part, anode part comprising an anode electrode grid plate and anode sludge attachment, a cathode part comprising a cathode electrode grid plate and accessory cathode;    (B) recycling the anode electrode grid board and attachment in an HNO3 solution for acid cleaning, where lead oxide (PbO) with HNO3 generates lead nitrate (Pb(NO3)2);    (C) taking out electrode grid plate, and filtering the reaction liquid, the filtrate is Pb(NO3)2 solution, filtering the residue comprising lead peroxide (PbO2) and PbSO4;    (D) reducing by placing the filter residue in ammonium sulfate ((NH4)2SO3) solution to react, filtering the reaction liquid to obtain a filtrate comprising (NH4)2SO4 solution, where the filter residue is PbO and PbSO4, continuously reacting the filter residue with the HNO3 solution, where PbO is converted to Pb(NO3)2, and filtering the reaction liquid, where the filtrate is Pb(NO3)2 solution and filter residue is PbSO4;    (E) cathode recycling by carrying out desulfurization comprising overcasting cathode electrode and grid plate attachment with PbSO4, placing the filter residue in NH4HCO3 solution for reaction, where PbSO4 is converted to lead carbonate (PbCO3), filtering the reaction solution, where filter residue is PbCO3, placing the filter residue in HNO3 solution, where PbCO3 is converted to Pb(NO3)2, separating out the liquid in the reaction of the electrode grid board , the rest solution is Pb(NO3)2 solution; electrode melting by heating the electrode plate to 350-400 degrees C, melting into lead liquid, and directly casting to an ingot; adding 20-98% H2SO4 solution to lead nitrate solution, stirring at room temperature for 30-60 minutes to generate lead sulfate, filtering the reaction solution, where the filter residue is lead sulfate, and the filtrate is nitric acid; and    (F) adding water to the filter residue to obtain paste, stirring, adding 10-30 mass % aqueous ammonia at 40-80 degrees C, reacting for 30-60 minutes, and filtering, where the filter residue is tribasic lead sulfate, and the filtrate is (NH4)2SO4 solution.
