The invention discloses a purification method and device of a desulfurization lead plaster filtrate. The method comprises the following steps: regulating the pH value of the filtrate, carrying out iron-carbon microelectrolysis to remove part of heavy metals and implement decolorization, and carrying out ion exchange to further remove high-valence cations. The device comprises a filtrate storage tank, a pH regulating tank, a primary purification tank, an aeration tank and a secondary purification tank. According to the method and device, the desulfurization lead plaster filtrate is subjected to deep purification to remove colored matters, heavy metal ions and other high-valence ions in the filtrate, thereby ensuring the subsequent filtrate crystallization to obtain high-grade sodium sulfate.
