Bromine　resources,　widely　utilized　in　basic　chemical　engineering,　are　considered　non-renewable.　A　substantial　amount　of　Bromine-Rich　Saline　Wastewater　(BRSW),　a　hazardous　waste,　is　generated　during　the　smelting　process　of　waste　printed　circuit　boards　(WPCBs).　The　efficient　conversion　of　bromine　resources　is　important　in　BRSW,　which　contain　high　concentrations　of　bromide　ions.　This　study　developed　a　synergistic　treatment　method　utilizing　electrolytic　manganese　anode　sludge　(EMAS)　achieved　efficient　conversion　of　Br-　to　Br-2　in　BRSW.　Optimal　technical　parameters　are　determined　through　single-factor　experiments,　and　the　oxidative　acid　leaching　process　was　optimized　using　response　surface　methodology　(RSM).　The　significant　influencing　factors　for　Br-　conversion　were　ranked　as　acidity　＞　anode　mud　addition　amount　＞　temperature　＞　time,　resulting　in　a　bromine　conversion　efficiency　of　96.55%.　Kinetic　studies　of　bromine　conversion　in　BRSW　during　the　oxidation-acid　leaching　process　indicated　a　two-stage　process:　Stage　I　being　a　chemical　reaction　control　model　and　Stage　II　being　a　diffusion　control　model.　The　reaction　mechanism　was　elucidated,　where　H+　initially　breaks　the　Mn-O　bond　in　MnO2,　exposing　O　vacancies　and　forming　Mn4+,　leading　to　a　redox　reaction　between　free　Br-　and　Mn4+.　This　research　embodies　the　concept　of　synergistic　solid　waste　disposal,　achieving　cost-effectiveness　and　streamlined　preparation　of　bromine,　and　providing　technical　and　theoretical　support　for　bromine　resource　recovery　in　BRSW.
