The　high　colority　and　hard　to　decolorization　were　the　most　important　tasks　on　printing　and　dyeing　waste　water.　The　ability　of　inactivated　aerobic　granular　sludge　(AGS)　to　adsorb　crystal　violet　(CV)　from　aqueous　solutions　using　fixed　bed　column　reactor　were　studied.　Column　adsorption　studies　were　carried　out　at　different　bed　heights,　initial　dye　concentrations　and　flow　rate.　Column　adsorption　experimental　data　and　corresponding　parameters　were　obtained　by　Thomas　model　and　bed　depth　service　time　(BDST)　model.　Results　showed　that　as　the　height　of　adsorbent　was　increasing,　breakthrough　time　and　adsorption　saturation　time　became　longer.　But　when　the　initial　dye　concentrations　and　flow　rate　were　increasing,　breakthrough　time　and　adsorption　saturation　time　became　shorter.　Thomas　model　described　column　adsorption　of　CV　kinetics　well.　When　concentration　of　CV　at　100　mg/L,　flow　rate　at　8.3mL/min　and　fixed　bed　height　at　20　cm,　Thomas　model　showed　good　agreement　with　the　experimental　results　(R2=0.9813).　BDST　model　could　predict　breakthrough　time　accurately　and　average　error　were　less　than　ten　percent.　Desorption　of　CV　from　AGS　was　using　Ethyl　alcohol　absolute.　©,　2015,　Chinese　Society　for　Environmental　Sciences.　All　right　reserved.
