Abstract：

Ammonia　adsorption　by　a　adsorbent,　aerobic　granular　sludge　cultured　in　a　lab-scale　SBR,　and　influencing　factors　were　studied　at　(25±1)°C　and　in　0.1　mol·L-1　Trise-HCl　buffer　reaction　system.comparing　with　flocculent　activated　sludge　the　aerobic　granular　sludge　exhibited　higher　adsorption　capacity.　At　initial　ammonia　concentration　of　30　mg·L-1,　the　adsorption　capacity　was　1.83　and　1.18　mg　NH4+-N·(g　VSS)-1　for　granular　sludge　and　flocculent　sludge,　respectively.　It　decreased　with　biomass　concentration　because　of　screen　effect　between　cells.　The　effect　of　salinity　(NaCl)　on　the　ammonia　adsorption　was　significant,　i.　e.　it　decreased　with　increase　of　salinity.　The　results　indicated　that　the　ammonia　adsorption　by　granular　sludge　should　not　be　neglected,　more　investigation　would　be　needed.　©　All　Rights　Reserved.
