A　novel　Ag　3　PO　4　/ZnWO　4　-modified　graphite　felt　electrode　(AZW@GF)　was　prepared　by　drop　coating　method　and　applied　to　photoelectrocatalytic　removal　of　harmful　algae.　Results　showed　that　approximately　99.21%　of　chlorophyll　a　and　91.57%　of　Microcystin-LR　(MCLR)　were　degraded　by　the　AZW@GF-Pt　photoelectrocatalytic　system　under　the　optimal　operating　conditions　with　a　rate　constant　of　0.02617　min　-1　and　0.01416　min　-1　,　respectively.　The　calculated　synergistic　coefficient　of　photoelectrocatalytic　algal　removal　and　MC-LR　degradation　by　the　AZW@GF-Pt　system　was　both　larger　than　1.9.　In　addition,　the　experiments　of　quenching　experiments　and　electron　spin　resonance　(ESR)　revealed　that　the　photoelectrocatalytic　reaction　mainly　generated　center　dot　OH　and　center　dot　O　2　-　for　algal　removal　and　MC-LR　degradation.　Furthermore,　the　potential　pathway　for　photoelectrocatalytic　degradation　of　MC-LR　was　proposed.　Finally,　the　photoelectrocatalytic　cycle　algae　removal　experiments　were　carried　out　on　AZW@GF　electrode,　which　was　found　to　maintain　the　algae　removal　efficiency　at　about　91%　after　three　cycles　of　use,　indicating　that　the　photoelectrocatalysis　of　AZW@GF　electrode　is　an　effective　emergency　algae　removal　technology.
