The　effects　of　different　Ru　doped　quantities　on　electrochemical　properties　and　surface　structures　of　Ti/Ru/SnO2+Sb2O5　electrode　were　investigated　in　this　experiment.　The　results　show　that　the　electrode　has　a　longer　accelerated　life　under　the　condition　of　10%　Ru　doped,　6　coating　layers,　600　℃　calcination　temperatures　and　1　h　burning　time.　Under　these　conditions,　the　characteristic　peak　intensity　of　SnO2　is　higher　and　narrower.　The　coating　surface　of　electrode　is　smooth　and　no　cracks.　When　treating　MBR　effluent　of　landfill　leachate　with　the　electrode　under　the　condition　of　10%　Ru　doped,　the　removal　rate　of　COD　was　93.33%,　and　the　aromaticity　can　greatly　reduce.　Humus　and　aromatic　compounds　also　can　be　reduced　under　this　doped　contents.　©　2018,　Science　Press.　All　right　reserved.
