Polymer　flooding　produced　water　is　a　taxonomic　group　of　refractory　wastewaters　with　a　high　viscosity　and　molecular　weight.　The　discharge　of　water　that　contains　hydrolyzed　polyacrylamide　(HPAM)　into　the　environment　will　result　in　many　environmental　problems.　The　use　of　the　electro-oxidation　(EO)　method　for　the　degradation　of　wastewater　is　characterized　by　many　advantages,　including　high　efficiency,　wide　applicability,　simplicity,　and　easy　operation.　In　this　study,　HPAM　was　degraded　using　Ti/SnO2-Sb2O3/beta-PbO2　anodes.　The　physicochemical　properties　of　the　electrodes　were　characterized　via　scanning　electron　microscopy　(SEM)　and　X-ray　diffraction　()(RD).　HPAM　degradation　experiments　were　carried　out　at　current　densities　of　10-40　mA/cm(2),　electrode　distances　of　1-5　cm,　initial　solution　pH　values　of　3-7,　and　electrolyte　concentrations　of　2000-10000　mg/L.　The　degradation　kinetics　studies　showed　that　the　HPAM　degraded　by　the　EO　process　followed　a　pseudo-first-order　kinetic　model　under　various　conditions.　Under　the　optimal　conditions,　namely　a　current　density　of　20　mA/cm(2),　electrode　distance　of　1　cm,　initial　pH　of　5,　and　electrolyte　concentration　of　6000　mg/L,　the　efficiency　of　the　electrochemical　degradation　of　HPAM　attained　100%.　Finally,　the　degradation　mechanism　and　products　of　HPAM　were　determined　via　monitoring　ion　chromatography　(IC),　three-dimensional　excitation　emission　matrix　(3D　EEM)　fluorescence　spectra,　Fourier　transform　infrared　spectroscopy　(FT-IR),　the　total　organic　carbon　(TOC),　and　gas　chromatography/mass　spectrometry　(GC/MS).
