摘要：

How　to　get　stable　and　sufficient　nitrite　as　an　electronic　acceptor　of　anammox　bacteria　is　a　bottleneck　of　nitrogen　removal　in　treatment　of　municipal　wastewater　by　anaerobic　ammonium　oxidation　reaction　processes.　Therefore,　denitrification　processes　was　considered　as　an　alternative　to　obtain　stable　nitrite.　The　nitrite　accumulation　during　denitrification　processes　was　studied　in　a　bench-scale　sequencing　batch　reactor　with　methanol　as　carbon　source　by　controlling　initial　C/N(COD/NO3--N)　ratios　in　influent.　The　results　showed　that,　the　shortage　of　methanol　feed(C/N　ratios　2--N　and　NO3--N　goes　up　with　the　concentration　of　COD　when　C/N　ratios
