In　order　to　research　the　adsorption　of　estrone　(E1),　17-estradiol　(E2)　and　17-ethynylestradiol　(EE2)　onto　aerobic　granular　sludge,　the　adsorption　balance　time　and　the　biosorption　behavior　under　different　temperatures　were　studied.　The　experiment　data　were　fit　with　Freundlich　equation　and　Langmuir　equation.　The　structure　of　AGS　was　observed　by　SEM.　The　results　show　that　the　adsorption　equilibrium　is　within　40　min,　and　the　maximum　adsorption　capacity　(qmax)　decreases　with　increasing　temperature.　The　qmax　s　of　E1,　E2,　EE2　are　60.98,　58.82,　and　82.64　μg/g　respectively　at　20C.　This　adsorption　process　is　in　conformity　with　the　isothermal　adsorption　equation　of　Langmuir　and　Freundlich　with　R2　correlation　coefficient　between　0.93~0.98　and　0.92~0.98,　respectively.　The　results　of　SEM　show　that　there　are　changes　in　the　internal　and　external　morphology　of　AGS.
