The invention discloses a persulfate electrolysis production device which comprises multiple electrolytic cell frameworks mounted on an electrolytic cell mounting rack, wherein frame surfaces of two adjacent electrolytic cell frameworks are tightly arranged in parallel with each other; a sealing element used for sealing a gap between binding faces of the electrolytic cell frameworks is arranged between the frame surfaces of the two adjacent electrolytic cell frameworks; a separation disc is respectively arranged in the middle in each electrolytic cell framework; the periphery of each separation disc is fixedly connected with an inner wall of a corresponding electrolytic cell framework; a cavity in the electrolytic cell framework in which the separation disc is positioned is separated into a cathode chamber and an anode chamber by each separation disc; the cathode chambers and anode chambers on the multiple electrolytic cell frameworks are arranged at intervals according to a sequence of a cathode chamber, an anode chamber, another cathode chamber and another anode chamber. The invention aims to provide a persulfate electrolysis production device which is high in operating current efficiency, low in electrolysis energy consumption, low in cost of electrolysis production materials, simple in production process and capable of directly producing persulfate through electrolysis.
