A　microcystin　detection　and　Environmental　Scanning　Electron　Microscope　investigation　were　carried　out　to　analyze　the　microcystin　removal　effect　and　the　forms　of　Microcystis　aeruginosa　cells　with　different　dosage　of　potassium　permanganate　loaded　zeolite.　The　results　showed　that　potassium　permanganate　loaded　zeolite　had　significant　microcystin-LR　removal　effect　both　in　the　Microcystis　aeruginosa　and　Nostoc　samples.　The　optimal　dosage　and　the　optimal　removal　rate　were　96.0%　at　220mg/L　and　77%　at　110mg/L　separately.　The　cell　wall　of　Microcystis　aeruginosa　was　ruptured　by　dosing　both　potassium　permanganate　and　potassium　permanganate　loaded　zeolite,　while　algae　cells　were　accumulated.　Cell　groups　treated　by　potassium　permanganate　loaded　zeolite　appeared　more　compact　to　improve　cells　settling　performance　and　wrapped　exudates　to　avoid　microcystin　excessing　into　water.　There　were　abundant　adsorption　sites　to　adsorb　intracellular　and　extracellular　microcystin　after　potassium　permanganate　released　from　zeolite.
