Different　feeding　modes　with　different　influent　substrate　concentration　were　investigated　using　anaerobic　SBR,　with　the　conditions　of　synthetic　wastewater　and　real　mature　landfill　leachate,　respectively.　The　results　showed　that　when　treating　low　concentration　of　synthetic　wastewater　(NO2--N≤400　mg/L),　the　feeding　mode　of　5　min　was　a　better　choice　for　Anammox.　When　treating　high　concentration　of　synthetic　wastewater　(NO2--N≥400　mg/L),　the　continuous　feeding　mode　of　5　h　was　the　best　choice　for　Anammox.　Under　the　continuous　feeding　mode　of　5h,　the　average　nitrogen　removal　rate　(ANRR)　increased　to　39.11　mgN/(gVSS·h)　and　enhanced　by　40%　comparing　with　the　feeding　mode　of　5min.　When　treating　the　real　mature　landfill　leachate　with　nitrite　concentration　of　300±20　mg/L,　ANRR　of　5　h　was　maximum　comparing　with　other　feeding　modes.　Because　of　the　mature　landfill　leachate　contained　a　little　of　biodegradable　organics　and　lots　of　hazardous　substances,　the　ANRR　of　treating　mature　landfill　leachate　was　lower　than　that　of　treating　synthetic　wastewater.　©,　2015,　Chinese　Society　for　Environmental　Sciences.　All　right　reserved.
