Abstract：

The　feasibility　of　completely　autotrophic　nitrogen　removal　process　(CANON)　for　treating　domestic　sewage　at　ambient　temperature　was　investigated　in　MBR.　Firstly,　the　hydraulic　retention　time　(HRT)　was　gradually　reduced　without　variation　of　influent　ammonia　for　enriching　AOB,　then　HRT　was　further　decreased　with　the　reduction　of　aeration　rate　for　enriching　anammox,　and　DGGE　was　adopted　in　this　study　for　analysis　of　the　community　dynamics　in　different　phases.　CANON　was　successfully　started-up　within　78　days,　finally　total　nitrogen　removal　rate　reached　0.96　kg·m-3·d-1　with　the　removal　efficiency　of　80%,　COD　and　ammonia　were　simultaneously　removed　when　treating　domestic　sewage.　Phylogenetic　analysis　indicated　that　Nitrosomonas　related　ammonia　oxidizing　bacteria　and　Candidatus　Kuenenia　stuttgariensis　like　ANAMMOX　bacteria　existed　in　the　reactor.　The　MBR-CANON　system　was　feasible　for　treating　domestic　wastewater　at　ambient　temperature.
