Active　carbon　(AC)　supported　copper　(Cu/AC)　catalysts　were　prepared　with　impregnation　method　and　tested　by　catalytic　wet　peroxide　oxidation(CWPO)　of　leachate　from　a　refuse　transfer　station.　COD　removal　rate　was　used　to　evaluate　the　catalytic　activity　and　stability　in　this　paper.　The　influence　of　calcination　temperature,　calcination　time　and　impregnation　concentration　on　catalytic　activity　were　studied　with　experiments.　The　catalyst　was　characterized　by　XRD　and　BET.　The　results　showed　that　under　the　optimal　conditions:　calcination　temperature　of　400℃,　calcination　time　of　2　h　and　impregnation　concentration　of　0.4　mol·L　-1　,　the　COD　removal　rate　could　reach　89.9%.　UV-vis　spectra　and　three　dimensional　fluorescence　spectra　(3DEEM)　analysis　showed　that　refractory　organics　in　leachate　can　be　removed　effectively　by　CWPO　with　the　prepared　AC/Cu　catalyst.　The　results　of　repeated　use　of　the　catalyst　showed　that　the　prepared　catalyst　has　good　stability.　©　2017,　Science　Press.　All　right　reserved.
