Abstract：

The　effect　of　organic　carbon　source　on　the　granulation　of　anaerobic　ammonium　oxidation　(Anammox)　sludge　was　tested　in　two　parallel　SBRs　by　gradually　increasing　the　concentration　of　organic　carbon　source　(R1)　and　by　adding　no　organic　carbon　(R2).　Results　showed　that　appropriate　concentration　of　organic　carbon　source　(　230　mg/L)　disintegrated　sludge,　reduced　particle　size,　and　worsened　sludge　settling　performance　significantly.　Organic　carbon　source　with　a　concentration　lower　than　110　mg/L　promoted　the　anaerobic　ammonia　oxidation　by　denitrification,　thereby　improving　N-removal　efficiency.　In　contrast,　when　the　concentration　of　organic　carbon　source　was　higher　than　110　mg/L,　anaerobic　ammonia　oxidation　was　inhibited　and　N-removal　efficiency　was　decreased.　Therefore,　the　concentration　of　organic　carbon　source　should　be　equal　to　or　lower　than　110　mg/L　during　the　operation　of　Anammox　reactor.　©　2018,　Editorial　Board　of　Journal　of　Harbin　Institute　of　Technology.　All　right　reserved.
